^ Operator (C# Reference)
Binary ^ operators are predefined for the integral types and bool. For integral types, ^ computes the bitwise exclusive-OR of its operands. For bool operands, ^ computes the logical exclusive-or of its operands; that is, the result is true if and only if exactly one of its operands is true.
Remarks
User-defined types can overload the ^ operator (see operator). Operations on integral types are generally allowed on enumeration.
Example
class XOR
{
static void Main()
{
Console.WriteLine(true ^ false); // logical exclusive-or
Console.WriteLine(false ^ false); // logical exclusive-or
// Bitwise exclusive-or:
Console.WriteLine("0x{0:x}", 0xf8 ^ 0x3f);
}
}
/*
Output:
True
False
0xc7
*/
