Why are these enums bad

Question

In Visual Studio -- well, I am using Visual Studio 11 Beta, so that might be the issue -- I think I am coding enums ok. But while this works:

This does not work:

What is wrong?

Out of curiosity, what kind of triangle would (100, 1, 1) be? — Greg Hewgill, May 30 '12 at 03:19
@Greg: oooo, you got a point. It could not be a triangle at all !! — xarzu, May 30 '12 at 04:12

Nothing to do with the VS11 beta. You just have to prefix with the enum name:

return TriangleType.error;

C# is a strong typed language. You are missing the enum name before the enum value. This should work:

return TriangleType.error;

and so on...

Talking of strong typing regarding C# enums is a bit misleading, especially given that you could return values outside the enum, too ;-) – Joey May 30 '12 at 09:20

If you wanted to do as in your first example and return an int you could cast the value and still use the enum "names", as in:

return (int)TriangleType.scalene;

See this other SO question for more information.
