C# Bitwise and Bit Shift Operators

Csharp Server Side Programming Programming

Bitwise operator works on bits and performs bit by bit operation.

The Bitwise operators supported by C# are listed in the following table. Assume variable A holds 60 and variable B holds 13 −

Operator	Description	Example
&	Bitwise AND Operator copies a bit to the result if it exists in both operands.	(A & B) = 12, which is 0000 1100
\|	Bitwise OR Operator copies a bit if it exists in either operand.	(A \| B) = 61, which is 0011 1101
^	Bitwise XOR Operator copies the bit if it is set in one operand but not both.	(A ^ B) = 49, which is 0011 0001
~	Bitwise One's Complement Operator is unary and has the effect of 'flipping' bits.	(~A ) = 61, which is 1100 0011 in 2's complement due to a signed binary number.
<<	Bitwise Left Shift Operator The left operands value is moved left by the number of bits specified by the right operand.	A << 2 = 240, which is 1111 0000
>>	Bitwise Right Shift Operator The left operands value is moved right by the number of bits specified by the right operand.	A >> 2 = 15, which is 0000 1111

Example

The following is an example showing how to implement the Bitwise operators in C#.

Live Demo

using System;
namespace MyApplication {
   class Program {
      static void Main(string[] args) {
         int a = 60; /* 60 = 0011 1100 */
         int b = 13; /* 13 = 0000 1101 */
         int c = 0;
         // Bitwise AND Operator
         c = a &amp; b; /* 12 = 0000 1100 */
         Console.WriteLine("Line 1 - Value of c is {0}", c );
         // Bitwise OR Operator
         c = a | b; /* 61 = 0011 1101 */
         Console.WriteLine("Line 2 - Value of c is {0}", c);
         // Bitwise XOR Operator
         c = a ^ b; /* 49 = 0011 0001 */
         Console.WriteLine("Line 3 - Value of c is {0}", c);
         // Bitwise Complement Operator
         c = ~a; /*-61 = 1100 0011 */
         Console.WriteLine("Line 4 - Value of c is {0}", c);
         // Bitwise Left Shift Operator
         c = a << 2; /* 240 = 1111 0000 */
         Console.WriteLine("Line 5 - Value of c is {0}", c);
         // Bitwise Right Shift Operator
         c = a >> 2; /* 15 = 0000 1111 */
         Console.WriteLine("Line 6 - Value of c is {0}", c);
         Console.ReadLine();
      }
   }
}

Output

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
