Bitwise operators act on bits and perform operations bit by bit.
C# supports bitwise operators as shown in the following table. Suppose variable A is 60 and variable B is 13 -
Operator | Description | Example |
---|---|---|
Bitwise AND operator copies a bit to the result (if present in both operands). | (A & B) = 12, which is 0000 1100 | |
The bitwise OR operator copies a bit if it exists in either operand. |
(A | B) = 61, which is 0011 1101 |
##^ |
The bitwise XOR operator copies the bit if it is set in one operand but not both. | (A ^ B) = 49, which is 0011 0001 | ##~ |
The bitwise complement operator is unary and has the effect of "flipping" bits. | (~A ) = 61, which is 2's complement 1100 0011 since it is a signed binary number. | |
Bitwise left shift operator The value of the left operand Shift left by the number of bits specified by the right operand. |
A |
##>> |
The value of the left operand is shifted to the right by the number of bits specified by the right operand. | A >> 2 = 15, which is 0000 1111 | ##Example | The following example shows how to implement 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(); } } }
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
