Can you use the "return" statement in C# methods declared as void?

Question

While reading an MCSD study guide, I noticed the author said it was illegal to include a return statement in a method that declares the return type void. However, when I created the following method Visual Studio didn't flag it in the editor nor did it fail to compile:

private void ReturnNothing()
{
    return;
}

What is the real answer then? Is this legal?

Answer 1

Yes it's definitely legal.

It's only illegal if you try to put a value after the return. This is wrong return 0;
