Does C# allow double semicolon ; ; if so, are there any special ways?

Question

I am writing a statement and it compiles, but the compiler [VS] never tells me that I put the semicolon two times.

This means in ASP.NET MVC 3

return         


        

Answer 1

No, a double semi-colon is never required. I'm slightly surprised that the compiler doesn't complain that it's an unreachable statement, but apparently it's legal. It won't do any harm, but equally it's not a good idea.
