DotNetDefer

A simple library to bring GoLang's defer functionality to .NET!

• DotNetDefer
  • Implements IDisposable and IAsyncDisposable, and can be used with Action, Func<T> Func<Task> and Func<Task<T>>
• DotNetDefer.Legacy
  • Implements only IDisposable and can be used with Actions and Funcs

Usage

using DotNetDefer;

class Program
{
    static void Main(string[] args)
    {
      var process = new MyLongProcess();
      process.Start();
      using var defer = new Defer(() => process.Stop());
  
      // Do some work
    }
}

Installation

dotnet add package DrEsteban.DotNetDefer

Install-Package DrEsteban.DotNetDefer

There's also a version of the package that targets netstandard2.0 for compatibility with older projects. (E.g. projects that don't support IAsyncDisposable)

Install-Package DrEsteban.DotNetDefer.Legacy
