Add and remove values from flagged enum

This code is to add and remove a value from a flagged enum-instance:

[Flags]
public enum MyEnum
{
    Flag1 = 1 << 0,
    Flag2 = 1 << 1,
    Flag3 = 1 << 2
}

var value = MyEnum.Flag1;

// set additional value
value |= MyEnum.Flag2;  //value is now Flag1, Flag2
value |= MyEnum.Flag3;  //value is now Flag1, Flag2, Flag3

// remove flag
value &= ~MyEnum.Flag2; //value is now Flag1, Flag3
