Define an enum derived from byte, eg.

[Flags]
enum MyEnum : byte
{
One = 1,
Two = 2
}

To clear a flag you can write code like this:

MyEnum someVal &= ~MyEnum.One;

The C# compiler has no problems with this and it seems to work OK, however R# reports the "~MyEnum.One" code as an error: "Overflow in constant value computation"
