Weird line of c# code that works
return Json(new { ErrorMessag开发者_Python百科e = scheduleBase.ErrorMessage }, JsonRequestBehavior.AllowGet); ;
Is this just a weird case of me not being able to correctly see what the other semi-colon relates to? This code compiles and actually works fine, but I'm stumped as to why.
I found it in a co-workers code.
The extra semicolon is an empty statement after the return ...;
.
It is useless and harmless.
Empty statements are useful as loop bodies:
while (str[++i] != '#')
;
They're also a common source of bugs:
if (something) ;
{
...
}
This block is not connected to the if
statement; the condition only applies to the empty statement.
The C# compiler will give a warning here.
Extra semicolons aren't errors.
