How to Compare Flags in C#?

Question

I have a flag enum below.

[Flags]
public enum FlagTest
{
    None = 0x0,
    Flag1 = 0x1,
    Flag2 = 0x2,
    Flag3 = 0x4
}

I cannot make

Answer 1

For bit operations, you need to use bitwise operators.

This should do the trick:

if ((testItem & FlagTest.Flag1) == FlagTest.Flag1)
{
    // Do something,
    // however This is never true.
}

Edit: Fixed my if check - I slipped back into my C/C++ ways (thanks to Ryan Farley for pointing it out)
