^= Operator

The exclusive-OR assignment operator.

lhs ^= expr

Where:

lhs
A storage location, property, or indexer.
expr
An expression.

Remarks

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).

Example

// cs_operator_xor_assignment.cs
using System;
class Test 
{
   public static void Main() 
   {
      int a = 0x0c;
      a ^= 0x06;
      Console.WriteLine("0x{0:x8}", a);
      bool b = true;
      b ^= false;
      Console.WriteLine(b);
   }
}

Output

0x0000000a
True
