^= Operator (C# Reference)
The exclusive-OR assignment operator.
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
class XORAssignment
{
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
*/
