Bitwise operator works on bits and performs bit by bit operation.
The following are the Bitwise operators.
| Operator | Description | Example |
|---|---|---|
| & | Binary AND Operator copies a bit to the result if it exists in both operands. | (A & B) = 12, which is 0000 1100 |
| | | Binary OR Operator copies a bit if it exists in either operand. | (A | B) = 61, which is 0011 1101 |
| ^ | Binary XOR Operator copies the bit if it is set in one operand but not both. | (A ^ B) = 49, which is 0011 0001 |
| ~ | Binary Ones 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. |
| << | Binary 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 |
| >> | Binary 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 |
The following is an example showing how to work with bitwise operators in C#.
Example
using System;
namespace Demo {
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("Value of c is {0}", c );
c = a | b; /* 61 = 0011 1101 */
Console.WriteLine("Value of c is {0}", c);
c = a ^ b; /* 49 = 0011 0001 */
Console.WriteLine("Value of c is {0}", c);
c = ~a; /*-61 = 1100 0011 */
Console.WriteLine("Value of c is {0}", c);
c = a << 2; /* 240 = 1111 0000 */
Console.WriteLine("Value of c is {0}", c);
c = a >> 2; /* 15 = 0000 1111 */
Console.WriteLine("Value of c is {0}", c);
Console.ReadLine();
}
}
}Output
Value of c is 12 Value of c is 61 Value of c is 49 Value of c is -61 Value of c is 240 Value of c is 15
