Is there an easier way of writing base 2 numbers in Flags?

Is there an easier way to write the integer value for enum flags witho开发者_运维技巧ut having to remember EACH base 2 number (I tend to get lost after 4096)?

If I use, let's say, 2*2*2*2, will that be converted to 16 at compile time or will it be executed at run time?

    public enum Foo
    {
        Bar  = 1 << 0,
        Baz  = 1 << 1,
        Quux  = 1 << 2,
        Etc  = 1 << 3
    }

You could use hex which is a little more intuitive.

Value1 = 0x01,
Value2 = 0x02,
Value3 = 0x04,
...

Or use bit shifts.

Value1 = 1 << 0,
Value2 = 1 << 1,
Value3 = 1 << 2,
....
