In this post, we’ll learn Bitwise operators in C#.
In c#, Bitwise Operators will work on bits, and these are useful to perform bit by bit operations such as Bitwise AND (&), Bitwise OR (|), Bitwise Exclusive OR (^), etc. on operands. We can perform bit-level operations on Boolean and integer data.
For example, we have integer variables a = 10, b = 20, and the binary format of these variables will be shown below.
a = 10 (00001010)
b = 20 (00010100)
When we apply the Bitwise OR (|) operator on these parameters, we will get the result shown below.
00001010
00010100

00011110 = 30 (Decimal)
The following table lists the different types of operators available in c# bitwise operators.
| Operator | Name | Description | Example (a = 0, b = 1) |
|---|---|---|---|
| & | Bitwise AND | It compares each bit of the first operand with the corresponding bit of its second operand. If both bits are 1, then the result bit will be 1; otherwise, the result will be 0. | a & b (0) |
| | | Bitwise OR | It compares each bit of the first operand with the corresponding bit of its second operand. If either of the bit is 1, then the result bit will be 1; otherwise, the result will be 0. | a | b (1) |
| ^ | Bitwise Exclusive OR (XOR) | It compares each bit of the first operand with the corresponding bit of its second operand. If one bit is 0 and the other bit is 1, then the result bit will be 1; otherwise, the result will be 0. | a ^ b (1) |
| ~ | Bitwise Complement | It operates on only one operand, and it will invert each bit of operand. It will change bit 1 to 0 and vice versa. | ~(a) (1) |
| << | Bitwise Left Shift) | It shifts the number to the left based on the specified number of bits. The zeroes will be added to the least significant bits. | b << 2 (100) |
| >> | Bitwise Right Shift | It shifts the number to the right based on the specified number of bits. The zeroes will be added to the least significant bits. | b >> 2 (001) |
C# Bitwise Operators Example
Following is the example of using the Bitwise Operators in the c# programming language.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
static void Main(string[] args) { int x = 5, y = 10, result; result = x & y; Console.WriteLine("Bitwise AND: " + result); result = x | y; Console.WriteLine("Bitwise OR: " + result); result = x ^ y; Console.WriteLine("Bitwise XOR: " + result); result = ~x; Console.WriteLine("Bitwise Complement: " + result); result = x << 2; Console.WriteLine("Bitwise Left Shift: " + result); result = x >> 2; Console.WriteLine("Bitwise Right Shift: " + result); Console.WriteLine("Press Enter Key to Exit.."); Console.ReadLine(); } |
If you observe the above code, we used different bitwise operators (&, |, ^, ~, <<, >>) to perform different operations on defined operands.
Output
When we execute the above c# program, we will get the result as shown below.
