The delegate disposable is a reusable implementation of the IDisposable interface. It calls the action that is passed in the constructor, when the object is disposed.

public class DelegateDisposable : IDisposable
{
    private readonly Action _disposeAction;

    public DelegateDisposable(Action disposeAction)
    {
        _disposeAction = disposeAction;
    }

    public void Dispose()
    {
        _disposeAction();
    }
}

Example usage:

IDisposable BeginTransaction()
{
    Console.Log("Transaction started...");
    return new DelegateDisposable(() => Console.Log("Transaction ended..."));
} 

using(var transaction = BeginTransaction())
{
    // Do something
}
