Operator “>” cannot be applied to type 'ulong' and 'int'

Question

I\'m curious to know why the C# compiler only gives me an error message for the second if statement.

enum Permissions : ulong
{
    ViewListItems = 1L,
}

pu         


        

Answer 1

It's not the CLR giving this error message it's the compiler.

In your first example the compiler treats 32 as ulong (or a type that's implicitly convertible to ulong eg uint) whereas in your second example you've explicitly declared the type as an int. There is no overload of the > operator that accepts an ulong and an int and hence you get a compiler error.
