C# Bitwise and Bit Shift Operators
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#.
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 & 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
