{
        //fs.CopyToFile(@"D:\1.bak");//同步复制大文件
        fs.CopyToFileAsync(@"D:\1.bak");//异步复制大文件
        string md5 = fs.GetFileMD5Async().Result;//异步获取文件的MD5
}

4.html的防XSS处理：

string html = @"<link href='/Content/font-awesome/css' rel='stylesheet'/>
        <!--[if IE 7]>
        <link href='/Content/font-awesome-ie7.min.css' rel='stylesheet'/>
        <![endif]-->
        <script src='/Scripts/modernizr'></script>
        <div id='searchBox' role='search'>
        <form action='/packages' method='get'>
        <span class='user-actions'><a href='/users/account/LogOff'>退出</a></span>
        <input name='q' id='searchBoxInput'/>
        <input id='searchBoxSubmit' type='submit' value='Submit' />
        </form>
        </div>";
string s = html.HtmlSantinizerStandard();//清理后：<div><span><a href="/users/account/LogOff">退出</a></span></div>

5.整理操作系统的内存：

Windows.ClearMemorySilent();

6.任意进制转换

NumberFormater nf = new NumberFormater(36);//内置2-62进制的转换
//NumberFormater nf = new NumberFormater("0123456789abcdefghijklmnopqrstuvwxyz");// 自定义进制字符，可用于生成验证码
string s36 = nf.ToString(12345678);
long num = nf.FromString("7clzi");
Console.WriteLine("12345678的36进制是：" + s36); // 7clzi
Console.WriteLine("36进制的7clzi是：" + num); // 12345678
var bin=12345678.ToBinary(36);//7clzi

7.纳秒级性能计时器

HiPerfTimer timer = HiPerfTimer.StartNew();
for (int i = 0; i < 100000; i++)
{
    //todo
}
timer.Stop();
Console.WriteLine("执行for循环100000次耗时"+timer.Duration+"s");
double time = HiPerfTimer.Execute(() =>
{
    for (int i = 0; i < 100000; i++)
    {
        //todo
    }
});
Console.WriteLine("执行for循环100000次耗时"+time+"s");

8.单机产生唯一有序的短id

var token=Stopwatch.GetTimestamp().ToBinary(36);
var set = new HashSet<string>();
double time = HiPerfTimer.Execute(() =>
{
    for (int i = 0; i < 1000000; i++)
    {
        set.Add(Stopwatch.GetTimestamp().ToBinary(36));
    }
});
Console.WriteLine(set.Count==1000000);//True
Console.WriteLine("产生100w个id耗时"+time+"s");//1.6639039s

9.产生分布式唯一有序短id

var sf = SnowFlake.GetInstance();
string token = sf.GetUniqueId();// rcofqodori0w
string shortId = sf.GetUniqueShortId(8);// qodw9728
var set = new HashSet<string>();
double time = HiPerfTimer.Execute(() =>
{
    for (int i = 0; i < 1000000; i++)
    {
        set.Add(SnowFlake.GetInstance().GetUniqueId());
    }
});
Console.WriteLine(set.Count == 1000000); //True
Console.WriteLine("产生100w个id耗时" + time + "s"); //2.6891495s

10.农历转换

ChineseCalendar.CustomHolidays.Add(DateTime.Parse("2018-12-31"),"元旦节");//自定义节假日
ChineseCalendar today = new ChineseCalendar(DateTime.Parse("2018-12-31"));
Console.WriteLine(today.ChineseDateString);// 二零一八年十一月廿五
Console.WriteLine(today.AnimalString);// 生肖：狗
Console.WriteLine(today.GanZhiDateString);// 干支：戊戌年甲子月丁酉日
Console.WriteLine(today.DateHoliday);// 获取按公历计算的节假日
...

11.Linq表达式树扩展

Expression<Func<string, bool>> where1 = s => s.StartsWith("a");
Expression<Func<string, bool>> where2 = s => s.Length > 10;
Func<string, bool> func = where1.And(where2).Compile();
bool b=func("abcd12345678");//true
Expression<Func<string, bool>> where1 = s => s.StartsWith("a");
Expression<Func<string, bool>> where2 = s => s.Length > 10;
Func<string, bool> func = where1.Or(where2).Compile();
bool b=func("abc");// true

12.模版引擎

var tmp = new Template("{{name}}，你好！");
tmp.Set("name", "万金油");
string s = tmp.Render();//万金油，你好！
var tmp = new Template("{{one}},{{two}},{{three}}");
string s = tmp.Set("one", "1").Set("two", "2").Set("three", "3").Render();// 1,2,3
var tmp = new Template("{{name}}，{{greet}}！");
tmp.Set("name", "万金油");
string s = tmp.Render();// throw 模版变量{{greet}}未被使用

13.List转Datatable

var list = new List<MyClass>()
{
    new MyClass()
    {
        Name = "张三",
        Age = 22
    },
    new MyClass()
    {
        Name = "李四",
        Age = 21
    },
    new MyClass()
    {
        Name = "王五",
        Age = 28
    }
};
var table = list.Select(c => new{姓名=c.Name,年龄=c.Age}).ToList().ToDataTable();// 将自动填充列姓名和年龄

14.文件压缩解压

.NET Framework

MemoryStream ms = SevenZipCompressor.ZipStream(new List<string>()
{
    @"D:\1.txt",
    "http://ww3.sinaimg.cn/large/87c01ec7gy1fsq6rywto2j20je0d3td0.jpg",
});//压缩成内存流
SevenZipCompressor.Zip(new List<string>()
{
    @"D:\1.txt",
    "http://ww3.sinaimg.cn/large/87c01ec7gy1fsq6rywto2j20je0d3td0.jpg",
}, zip);//压缩成zip
SevenZipCompressor.UnRar(@"D:\Download\test.rar", @"D:\Download\");//解压rar
SevenZipCompressor.Decompress(@"D:\Download\test.tar", @"D:\Download\");//自动识别解压压缩包
SevenZipCompressor.Decompress(@"D:\Download\test.7z", @"D:\Download\");

ASP.NET Core

Startup.cs

services.AddSevenZipCompressor();

构造函数注入ISevenZipCompressor

private readonly ISevenZipCompressor _sevenZipCompressor;
public Test(ISevenZipCompressor sevenZipCompressor)
{
    _sevenZipCompressor = sevenZipCompressor;
}

使用方式同.NET Framework版本

15.日志组件

LogManager.LogDirectory=AppDomain.CurrentDomain.BaseDirectory+"/logs";
LogManager.Event+=info =>
{
    //todo:注册一些事件操作
};
LogManager.Info("记录一次消息");
LogManager.Error(new Exception("异常消息"));

16.FTP客户端

FtpClient ftpClient = FtpClient.GetAnonymousClient("192.168.2.2");//创建一个匿名访问的客户端
//FtpClient ftpClient = FtpClient.GetClient("192.168.2.3","admin","123456");// 创建一个带用户名密码的客户端
ftpClient.Delete("/1.txt");// 删除文件
ftpClient.Download("/test/2.txt","D:\\test\\2.txt");// 下载文件
ftpClient.UploadFile("/test/22.txt","D:\\test\\22.txt",(sum, progress) =>
{
    Console.WriteLine("已上传："+progress*1.0/sum);
});//上传文件并检测进度
List<string> files = ftpClient.GetFiles("/");//列出ftp服务端文件列表
...

17.多线程后台下载

var mtd = new MultiThreadDownloader("https://attachments-cdn.shimo.im/yXwC4kphjVQu06rH/KeyShot_Pro_7.3.37.7z",Environment.GetEnvironmentVariable("temp"),"E:\\Downloads\\KeyShot_Pro_7.3.37.7z",8);
mtd.TotalProgressChanged+=(sender, e) =>
{
    var downloader = sender as MultiThreadDownloader;
    Console.WriteLine("下载进度："+downloader.TotalProgress+"%");
    Console.WriteLine("下载速度："+downloader.TotalSpeedInBytes/1024/1024+"MBps");
};
mtd.FileMergeProgressChanged+=(sender, e) =>
{
    Console.WriteLine("下载完成");
};
mtd.Start();//开始下载
//mtd.Pause(); // 暂停下载
//mtd.Resume(); // 继续下载

18.Socket客户端操作类

var tcpClient = new TcpClient(AddressFamily.InterNetwork);
Socket socket = tcpClient.ConnectSocket(IPAddress.Any,5000);
socket.SendFile("D:\\test\\1.txt",false,i =>
{
    Console.WriteLine("已发送"+i+"%");
});

19.RedisHelper

.Net Framework:

RedisHelper redisHelper = RedisHelper.GetInstance();// 获取新实例并指定连接第0个数据库
//RedisHelper redisHelper = RedisHelper.GetInstance(2);// 获取新实例并指定连接第2个数据库
//RedisHelper redisHelper = RedisHelper.GetInstance("192.168.3.150:6379");// 获取新实例并指定连接第0个数据库
//RedisHelper redisHelper = RedisHelper.GetInstance("192.168.3.150:6379",2);// 获取新实例并指定连接第2个数据库
//RedisHelper redisHelper = RedisHelper.GetSingleInstance();// 获取单例实例并指定连接第2个数据库
//RedisHelper redisHelper = RedisHelper.GetSingleInstance(2);// 获取单例实例并指定连接第2个数据库
//RedisHelper redisHelper = RedisHelper.GetSingleInstance("192.168.3.150:6379");// 获取单例实例并指定连接第0个数据库
//RedisHelper redisHelper = RedisHelper.GetSingleInstance("192.168.3.150:6379",2);// 获取单例实例并指定连接第2个数据库
redisHelper.SetString("key","value");
string value = redisHelper.GetString("key");
redisHelper.ListLeftPush("list","value");
List<string> list = redisHelper.ListRange<string>("list");

Asp.Net Core依赖注入方式: Startup.cs:

services.AddDefaultRedisHelper("192.168.16.145:6379,password=xilife2018,connectTimeout=1000,connectRetry=1,syncTimeout=1000");//注入一个默认实例
services.AddLocalRedisHelper();// 注入本地实例
services.AddRedisHelper("aa", "192.168.16.145:6379,password=xilife2018,connectTimeout=1000,connectRetry=1,syncTimeout=1000");// 通用注入

Controller:

public RedisHelper RedisHelper { get; set; }
public HomeController(RedisHelperFactory redisHelperFactory)
{
    RedisHelper=redisHelperFactory.Create("aa",0);// 创建命名为aa的RedisHelper，指定数据库0
    RedisHelper=redisHelperFactory.CreateDefault(0); // 创建默认的RedisHelper，指定数据库0
    RedisHelper=redisHelperFactory.CreateLocal(0); // 创建连接本机的RedisHelper，指定数据库0
}

方法调用方式和.NET Framework方式相同

20.加密解密

var enc="123456".MDString();// MD5加密
var enc="123456".MDString("abc");// MD5加盐加密
var enc="123456".MDString2();// MD5两次加密
var enc="123456".MDString2("abc");// MD5两次加盐加密
var enc="123456".MDString3();// MD5三次加密
var enc="123456".MDString3("abc");// MD5三次加盐加密

string aes = "123456".AESEncrypt();// AES加密为密文
string s = aes.AESDecrypt(); //AES解密为明文
string aes = "123456".AESEncrypt("abc");// AES密钥加密为密文
string s = aes.AESDecrypt("abc"); //AES密钥解密为明文

string enc = "123456".DesEncrypt();// DES加密为密文
string s = enc.DesDecrypt(); //DES解密为明文
string enc = "123456".DesEncrypt("abcdefgh");// DES密钥加密为密文
string s = enc.DesDecrypt("abcdefgh"); //DES密钥解密为明文

RsaKey rsaKey = RsaCrypt.GenerateRsaKeys();// 生成RSA密钥对
string encrypt = "123456".RSAEncrypt(rsaKey.PublicKey);// 公钥加密
string s = encrypt.RSADecrypt(rsaKey.PrivateKey);// 私钥解密

21.Redis分布式锁

using (RedisLock redisLock = new RedisLock("127.0.0.1:6379"))
{
    if (redisLock.TryLock("lock", TimeSpan.FromSeconds(10), TimeSpan.FromSeconds(10), out var lockObject))// 加锁
    {
        //todo:需要执行的原子操作
    }

    var redisResult = redisLock.UnLock(lockObject);// 释放锁
}

22.实体校验

public class MyClass
{
    [IsEmail]
    public string Email { get; set; }

    [IsPhone]
    public string PhoneNumber { get; set; }

    [IsIPAddress]
    public string IP { get; set; }

    [MinValue(0, ErrorMessage = "年龄最小为0岁"), MaxValue(100, ErrorMessage = "年龄最大100岁")]
    public int Age { get; set; }

    [ComplexPassword]//密码复杂度校验
    public string Password { get; set; }
}

23.HTML操作

List<string> srcs = "html".MatchImgSrcs().ToList();// 获取html字符串里所有的img标签的src属性
var imgTags = "html".MatchImgTags();//获取html字符串里的所有的img标签
...

24.DateTime扩展

double milliseconds = DateTime.Now.GetTotalMilliseconds();// 获取毫秒级时间戳
double microseconds = DateTime.Now.GetTotalMicroseconds();// 获取微秒级时间戳
double nanoseconds = DateTime.Now.GetTotalNanoseconds();// 获取纳秒级时间戳
double seconds = DateTime.Now.GetTotalSeconds();// 获取秒级时间戳
double minutes = DateTime.Now.GetTotalMinutes();// 获取分钟级时间戳
...

25.IP地址和URL

bool inRange = "192.168.2.2".IpAddressInRange("192.168.1.1","192.168.3.255");// 判断IP地址是否在这个地址段里
bool isPrivateIp = "172.16.23.25".IsPrivateIP();// 判断是否是私有地址
bool isExternalAddress = "http://baidu.com".IsExternalAddress();// 判断是否是外网的URL

//以下需要配置baiduAK
string isp = "114.114.114.114".GetISP(); // 获取ISP运营商信息
PhysicsAddress physicsAddress = "114.114.114.114".GetPhysicsAddressInfo().Result;// 获取详细地理信息对象
Tuple<string, List<string>> ipAddressInfo = "114.114.114.114".GetIPAddressInfo().Result;// 获取详细地理信息集合

26.元素去重

var list = new List<MyClass>()
{
    new MyClass()
    {
        Email = "[email protected]"
    },
    new MyClass()
    {
        Email = "[email protected]"
    },
    new MyClass()
    {
        Email = "[email protected]"
    }
};
List<MyClass> classes = list.DistinctBy(c => c.Email).ToList();
Console.WriteLine(classes.Count==1);//True

27.对象实体映射

在使用前需要像automapper那样，对mapper进行初始化操作

using Masuit.Tools.Mapping;
ExpressionMapper.CreateMap<ClassA, ClassADto>();// 默认关系映射
ExpressionMapper.CreateMap<ClassB, ClassBDto>().ForMember(s => s.ClassC.PropertyName, d => d.CustomName, true);// 自定义关系映射

ExpressionMapper.ConstructServicesUsing((x) => DependencyResolver.Current.GetService(x));// 使用依赖注入容器进行构造映射
//ExpressionMapper.ConstructServicesUsing((x) => ServiceLocator.Current.GetInstance(x));// 使用依赖注入容器进行构造映射
ExpressionMapper.CreateMap<Product, IProduct>().ConstructUsingServiceLocator().ReverseMap();// 链式自定义关系映射和反向映射

测试class：

public class TestClassA
{
    public string MyProperty { get; set; }
    public int Int { get; set; }
    public double Double { get; set; }
    public DateTime DateTime { get; set; }
    public TestClassC TestClassC { get; set; }
    public List<TestClassC> List { get; set; }
}

public class TestClassB
{
    public string MyProperty { get; set; }
    public int Int { get; set; }
    public double Double { get; set; }
    public DateTime DateTime { get; set; }
    public TestClassC TestClassC { get; set; }
    public List<TestClassD> List { get; set; }
}

public class TestClassC
{
    public string MyProperty { get; set; }
    public int Int { get; set; }
    public double Double { get; set; }
    public DateTime DateTime { get; set; }
    public TestClassD Obj { get; set; }
}

public class TestClassD
{
    public string MyProperty { get; set; }
    public int Int { get; set; }
    public double Double { get; set; }
    public DateTime DateTime { get; set; }
    public TestClassC Obj { get; set; }
}

构造一个结构相对复杂的对象：

var a = new TestClassA()
{
    MyProperty = "ssssssssssssssssssssss",
    DateTime = DateTime.Now,
    Double = 123.33,
    Int = 100,

                Int = 10100000,
                Obj = new TestClassD()
            }
        }
    },
    List = new List<TestClassC>()
    {
        new TestClassC()
        {

                    Double = 2345.555,
                    Int = 10100,
                    Obj = new TestClassD()
                }
            }
        },
        new TestClassC()
        {
            MyProperty = "cccccc",
            DateTime = DateTime.Now,

    Read,
    
    [Display(Name = "写")]
    [Description("写")]

Dictionary<int, string> dic1 = typeof(MyEnum).GetDictionary();// 获取枚举值和字符串表示的字典映射
var dic2 = typeof(MyEnum).GetDescriptionAndValue();// 获取字符串表示和枚举值的字典映射
string desc = MyEnum.Read.GetDescription();// 获取Description标签
string display = MyEnum.Read.GetDisplay();// 获取Display标签的Name属性
var value = typeof(MyEnum).GetValue("Read");//获取字符串表示值对应的枚举值
string enumString = 0.ToEnumString(typeof(MyEnum));// 获取枚举值对应的字符串表示

30.反射操作

MyClass myClass = new MyClass();
PropertyInfo[] properties = myClass.GetProperties();// 获取属性列表
myClass.SetProperty("Email","[email protected]");//给对象设置值

//动态增删对象的属性
MyClass myClass = new MyClass();
var mc = myClass.AddProperty(new List<ClassHelper.CustPropertyInfo>()
{
    new ClassHelper.CustPropertyInfo(typeof(string), "Name", "张三"),
    new ClassHelper.CustPropertyInfo(typeof(double), "Number", 123456.0),
});//添加属性
object newObj = mc.DeleteProperty(new List<string>() { "Email", "Age", "IP", "PhoneNumber" });// 删除属性

image.MakeThumbnail(@"D:\2.jpg", 120, 80, ThumbnailCutMode.LockWidth);//生成缩略图

Bitmap bmp = new Bitmap(@"D:\1.jpg");
Bitmap newBmp = bmp.BWPic(bmp.Width, bmp.Height);//转换成黑白
Bitmap newBmp = bmp.CutAndResize(new Rectangle(0, 0, 1600, 900), 160, 90);//裁剪并缩放

bmp.RevPicUD(bmp.Width, bmp.Height);//上下镜像

35.随机数

Random rnd = new Random();
int num = rnd.StrictNext();//产生真随机数

Asp.Net MVC和Asp.Net Core的支持断点续传和多线程下载的ResumeFileResult

允许你在ASP.NET Core中通过MVC/WebAPI应用程序传输文件数据时使用断点续传以及多线程下载。

它允许提供ETag标题以及Last-Modified标题。 它还支持以下前置条件标题：If-Match，If-None-Match，If-Modified-Since，If-Unmodified-Since，If-Range。

支持 ASP.NET Core 2.0

从.NET Core2.0开始，ASP.NET Core内部支持断点续传。 因此只是对FileResult做了一些扩展。 只留下了“Content-Disposition” Inline的一部分。 所有代码都依赖于基础.NET类。

如何使用

.NET Framework

在你的控制器中，你可以像在FileResult一样的方式使用它。

using Masuit.Tools.Mvc;
using Masuit.Tools.Mvc.ResumeFileResult;
private readonly MimeMapper mimeMapper=new MimeMapper(); // 推荐使用依赖注入

public ActionResult ResumeFileResult()
{
    var path = Server.MapPath("~/Content/test.mp4");
    return new ResumeFileResult(path, mimeMapper.GetMimeFromPath(path), Request);
}

public ActionResult ResumeFile()
{
    return this.ResumeFile("~/Content/test.mp4", mimeMapper.GetMimeFromPath(path), "test.mp4");
}

public ActionResult ResumePhysicalFile()
{
    return this.ResumePhysicalFile(@"D:/test.mp4", mimeMapper.GetMimeFromPath(@"D:/test.mp4"), "test.mp4");
}

Asp.Net Core

要使用ResumeFileResults，必须在Startup.cs的ConfigureServices方法调用中配置服务：

using Masuit.Tools.AspNetCore.ResumeFileResults.Extensions;
public void ConfigureServices(IServiceCollection services)
{
    services.AddResumeFileResult();
}

然后在你的控制器中，你可以像在FileResult一样的方式使用它。

using Masuit.Tools.AspNetCore.ResumeFileResults.Extensions;
private const string EntityTag = "\"TestFile\"";

private readonly IHostingEnvironment _hostingEnvironment;

private readonly DateTimeOffset _lastModified = new DateTimeOffset(2016, 1, 1, 0, 0, 0, TimeSpan.Zero);

/// <summary>
/// 
/// </summary>
/// <param name="hostingEnvironment"></param>
public TestController(IHostingEnvironment hostingEnvironment)
{
    _hostingEnvironment = hostingEnvironment;
}

[HttpGet("content/{fileName}/{etag}")]
public IActionResult FileContent(bool fileName, bool etag)
{
    string webRoot = _hostingEnvironment.WebRootPath;
    var content = System.IO.File.ReadAllBytes(Path.Combine(webRoot, "TestFile.txt"));
    ResumeFileContentResult result = this.ResumeFile(content, "text/plain", fileName ? "TestFile.txt" : null, etag ? EntityTag : null);
    result.LastModified = _lastModified;
    return result;
}

[HttpGet("content/{fileName}")]
public IActionResult FileContent(bool fileName)
{
    string webRoot = _hostingEnvironment.WebRootPath;
    var content = System.IO.File.ReadAllBytes(Path.Combine(webRoot, "TestFile.txt"));
    var result = new ResumeFileContentResult(content, "text/plain")
    {
        FileInlineName = "TestFile.txt",
        LastModified = _lastModified
    };
    return result;
}

[HttpHead("file")]
public IActionResult FileHead()
{
    ResumeVirtualFileResult result = this.ResumeFile("TestFile.txt", "text/plain", "TestFile.txt", EntityTag);
    result.LastModified = _lastModified;
    return result;
}

[HttpPut("file")]
public IActionResult FilePut()
{
    ResumeVirtualFileResult result = this.ResumeFile("TestFile.txt", "text/plain", "TestFile.txt", EntityTag);
    result.LastModified = _lastModified;
    return result;
}

[HttpGet("stream/{fileName}/{etag}")]
public IActionResult FileStream(bool fileName, bool etag)
{
    string webRoot = _hostingEnvironment.WebRootPath;
    FileStream stream = System.IO.File.OpenRead(Path.Combine(webRoot, "TestFile.txt"));

    ResumeFileStreamResult result = this.ResumeFile(stream, "text/plain", fileName ? "TestFile.txt" : null, etag ? EntityTag : null);
    result.LastModified = _lastModified;
    return result;
}

[HttpGet("stream/{fileName}")]
public IActionResult FileStream(bool fileName)
{
    string webRoot = _hostingEnvironment.WebRootPath;
    FileStream stream = System.IO.File.OpenRead(Path.Combine(webRoot, "TestFile.txt"));

    var result = new ResumeFileStreamResult(stream, "text/plain")
    {
        FileInlineName = "TestFile.txt",
        LastModified = _lastModified
    };

    return result;
}

[HttpGet("physical/{fileName}/{etag}")]
public IActionResult PhysicalFile(bool fileName, bool etag)
{
    string webRoot = _hostingEnvironment.WebRootPath;

    ResumePhysicalFileResult result = this.ResumePhysicalFile(Path.Combine(webRoot, "TestFile.txt"), "text/plain", fileName ? "TestFile.txt" : null, etag ? EntityTag : null);
    result.LastModified = _lastModified;
    return result;
}

[HttpGet("physical/{fileName}")]
public IActionResult PhysicalFile(bool fileName)
{
    string webRoot = _hostingEnvironment.WebRootPath;

    var result = new ResumePhysicalFileResult(Path.Combine(webRoot, "TestFile.txt"), "text/plain")
    {
        FileInlineName = "TestFile.txt",
        LastModified = _lastModified
    };

    return result;
}

[HttpGet("virtual/{fileName}/{etag}")]
public IActionResult VirtualFile(bool fileName, bool etag)
{
    ResumeVirtualFileResult result = this.ResumeFile("TestFile.txt", "text/plain", fileName ? "TestFile.txt" : null, etag ? EntityTag : null);
    result.LastModified = _lastModified;
    return result;
}

以上示例将为您的数据提供“Content-Disposition：attachment”。 当没有提供fileName时，数据将作为“Content-Disposition：inline”提供。 另外，它可以提供ETag和LastModified标题。

[HttpGet("virtual/{fileName}")]
public IActionResult VirtualFile(bool fileName)
{
    var result = new ResumeVirtualFileResult("TestFile.txt", "text/plain")
    {
        FileInlineName = "TestFile.txt",
        LastModified = _lastModified
    };
    return result;
}
