Returning a method from a C# method

I found this post that explains how to pass methods as parameters in C#.

What I need to know is how to return a method as the result of another method invocation.

method = DoSomething()
result = method()

you need to use either Action<T> or Func<T>

Like this:

private Action<string> Returns(string user)
{
    return () => 
    {
        Console.WriteLine("Hey {0}", user);
    };
}

or this:

private Func<bool> TestsIsThirty(int value)
{
    return () => value == 30;
}

Most probably you want your return type to be a Delegate.
