^= Operator (C# Reference)


Updated: July 20, 2015

For the latest documentation on Visual Studio 2017 RC, see Visual Studio 2017 RC Documentation.

The exclusive-OR assignment operator.

An expression of the form

x ^= y  

is evaluated as

x = x ^ y  

except that x is only evaluated once. The ^ operator performs a bitwise exclusive-OR operation on integral operands and logical exclusive-OR on bool operands.

The ^= operator cannot be overloaded directly, but user-defined types can overload the ^ operator (see operator).

    class XORAssignment
        static void Main()
            int a = 0x0c;
            a ^= 0x06;
            Console.WriteLine("0x{0:x8}", a);
            bool b = true;
            b ^= false;
