Disposer

A Source Generator package that generates extension methods for enums, to allow fast "reflection".

This source generator requires the .NET 6 SDK. You can target earlier frameworks like .NET Core 3.1 etc, but the SDK must be at least 6.0.100

Add the package to your application using

dotnet add package Disposer

This adds a <PackageReference> to your project. You can additionally mark the package as PrivateAsets="all".

Setting PrivateAssets="all" means any projects referencing this one won't get a reference to the Disposer package. <br/>

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net6.0</TargetFramework>
  </PropertyGroup>

  <PackageReference Include="Disposer" Version="1.0.0" 
    PrivateAssets="all" />

</Project>

Adding the package will automatically add a marker attribute, [Disposable], to your project.

To use the generator, add the [EnumExtensions] attribute to an enum. For example:

[Disposer.Disposable]
public class MyClass
{
    partial void DisposeManaged()
    {
        // free managed resources here
    }

    partial void DisposeUnmanaged()
    {
        // free Unmanaged resources here
    }
}

This will generate a class another partial class which implement IDisposable interface:

partial class MyClass : global::System.IDisposable
{
    partial void DisposeManaged();
    partial void DisposeUnmanaged();

    private bool disposed = false;

    ~MyClass()
    {
        Dispose(false);
    }

    private void Dispose(bool disposing)
    {
        if (disposed)
            return;

        if (disposing)
        {
            DisposeManaged();
        }

        DisposeUnmanaged();

        disposed = true;
    }

    public void Dispose()
    {
        Dispose(true);
        global::System.GC.SuppressFinalize(this);
    }
}
