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

C# compiler does not allow ;; between if and else without braces and compiler will throw error in the below case.

if (condition == true)
                ; ; 
            else
                ;

Compiler Error:

Error   CS1513  } expected  and one warning "Possible mistaken empty statement"

So if you remove one semicolon it will work perfectly(or you need to add braces).
