In c# what does the ^ character do? [duplicate]

Answer 1

This is binary XOR operator.

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.

Answer 2

It's the logical XOR operator.

Answer 3

The ^ charater, or 'caret' character is a bitwise XOR opeartor. e.g.

using System;

class Program
{
    static void Main()
    {
        // Demonstrate XOR for two integers.
        int a = 5550 ^ 800;
        Console.WriteLine(GetIntBinaryString(5550));
        Console.WriteLine(GetIntBinaryString(800));
        Console.WriteLine(GetIntBinaryString(a));
        Console.WriteLine();

        // Repeat.
        int b = 100 ^ 33;
        Console.WriteLine(GetIntBinaryString(100));
        Console.WriteLine(GetIntBinaryString(33));
        Console.WriteLine(GetIntBinaryString(b));
    }

    /// <summary>
    /// Returns binary representation string.
    /// </summary>
    static string GetIntBinaryString(int n)
    {
        char[] b = new char[32];
        int pos = 31;
        int i = 0;

        while (i < 32)
        {
            if ((n & (1 << i)) != 0)
            {
                b[pos] = '1';
            }
            else
            {
                b[pos] = '0';
            }
            pos--;
            i++;
        }
        return new string(b);
    }
}
