SharpConfig

SharpConfig is a lightweight utility library for extending the functionality of IConfiguration in .NET applications. It simplifies retrieving configuration sections as strongly typed objects, with support for required sections and default naming conventions.

Features

• Retrieve configuration sections as strongly typed objects.
• Specify custom section names or use default naming based on the type.
• Exception handling for missing required configuration sections.

Installation

Currently not on nuget.org, clone this repo and reference project.

Usage

Basic Usage

1. Add a configuration source to your IConfiguration instance.
2. Use the extension methods GetAs<T> or GetRequiredAs<T> to retrieve configuration sections.

Examples

Example Configuration

Assume the following JSON configuration:

{  
  "MyClass": {  
    "Property": "Value"  
  },  
  "AnotherClass": {  
    "Property": "AnotherValue"  
  }  
}

Setting Up Configuration

using Microsoft.Extensions.Configuration;
using SharpConfig;

var configurationBuilder = new ConfigurationBuilder();  
configurationBuilder.AddJsonFile("appsettings.json");  
var configuration = configurationBuilder.Build();

Strongly Typed Access

public class MyClass  
{  
    public string Property { get; set; } = string.Empty;  
}

// Retrieve configuration section as a strongly typed object  
var myClass = configuration.GetAs<MyClass>();  
if (myClass != null)  
{  
    Console.WriteLine(myClass.Property); // Output: Value  
}

Handling Required Sections

try  
{  
    var requiredClass = configuration.GetRequiredAs<MyClass>();  
    Console.WriteLine(requiredClass.Property); // Output: Value  
}  
catch (ArgumentException ex)  
{  
    Console.WriteLine(ex.Message);  
}

Custom Section Names

By default, GetAs<T> and GetRequiredAs<T> use the type name as the section name. You can specify a custom name if needed:

var anotherClass = configuration.GetAs<MyClass>("AnotherClass");  
if (anotherClass != null)  
{  
    Console.WriteLine(anotherClass.Property); // Output: AnotherValue  
}

Target Framework Compatibility

This library targets .NET 8.0 and .NET 9.0 to provide broad compatibility and support modern features. The net8.0 build ensures functionality on .NET 8.0 while the net9.0 build allows access to APIs and optimizations available in .NET 9.0. For earlier frameworks you may clone the repository and adapt the code as needed, as the library is simple and easy to integrate.
