C# bitwise oerators

OperatorDescriptionExample
&Binary AND Operator copies a bit to the result if it exists in both operands.(A & B) will give 12 which is 0000 1100
|Binary OR Operator copies a bit if it exists in either operand.(A | B) will give 61 which is 0011 1101
^Binary XOR Operator copies the bit if it is set in one operand but not both.(A ^ B) will give 49 which is 0011 0001
~Binary Ones Complement Operator is unary and has the effect of 'flipping' bits.(~A ) will give -60 which is 1100 0011
<<Binary Left Shift Operator. The left operands value is moved left by the number of bits specified by the right operand.A << 2 will give 240 which is 1111 0000
>>Binary Right Shift Operator. The left operands value is moved right by the number of bits specified by the right operand.A >> 2 will give 15 which is 0000 1111

example

Try following example to understand all the bitwise operators available in C#:
using System;
namespace OperatorsAppl
{
    class Program
    {
        static void Main(string[] args)
        {
            int a = 60;            /* 60 = 0011 1100 */  
            int b = 13;            /* 13 = 0000 1101 */
            int c = 0;           

             c = a & b;           /* 12 = 0000 1100 */ 
             Console.WriteLine("Line 1 - Value of c is {0}", c );

             c = a | b;           /* 61 = 0011 1101 */
             Console.WriteLine("Line 2 - Value of c is {0}", c);

             c = a ^ b;           /* 49 = 0011 0001 */
             Console.WriteLine("Line 3 - Value of c is {0}", c);

             c = ~a;               /*-61 = 1100 0011 */
             Console.WriteLine("Line 4 - Value of c is {0}", c);

             c = a << 2;     /* 240 = 1111 0000 */
             Console.WriteLine("Line 5 - Value of c is {0}", c);

             c = a >> 2;     /* 15 = 0000 1111 */
             Console.WriteLine("Line 6 - Value of c is {0}", c);
            Console.ReadLine();
        }
    }
}
When the above code is compiled and executed, it produces following result:
Line 1 - Value of c is 12
Line 2 - Value of c is 61
Line 3 - Value of c is 49
Line 4 - Value of c is -61
Line 5 - Value of c is 240
Line 6 - Value of c is 15
