C# Bitwise Operators Example – Easy Explanation & Real-World Code

Alright, let’s talk about Bitwise Operators in C#. These little guys help you perform operations at the binary level. Sounds scary? Don’t worry! You don’t need to be a math genius to understand them. 😃

Think of it like switching lights on and off. Just 0s and 1s working together to get things done. If you’ve ever struggled with optimizing code, these operators are your secret weapon. Let’s break it down with a C# Bitwise Operators example.

🔍 How Bitwise Operators Work in C#

Bitwise operators work at the binary level, meaning they manipulate the individual bits of numbers. Before performing bitwise operations, C# converts numbers (integers, chars, etc.) into binary.

Each bit in a number is either 0 or 1, and bitwise operators perform operations directly on those bits.

📝 C# Bitwise Operators Table

Operator	Name	Description	Example (Decimal)	Example (Binary)	Result (Decimal)
&	AND	Sets bit to `1` if both bits are `1`, otherwise `0`	5 & 3	0101 & 0011	1
\|	OR	Sets bit to `1` if at least one bit is `1`	5 \| 3	0101 \| 0011	7
^	XOR	Sets bit to `1` if bits are different, otherwise `0`	5 ^ 3	0101 ^ 0011	6
~	NOT	Inverts all bits (1 → 0, 0 → 1)	~5	~0101	-6 (Two’s Complement)
<<	Left Shift	Moves bits left, filling with `0`	5 << 1	0101 << 1	10
>>	Right Shift	Moves bits right, keeping sign bit	5 >> 1	0101 >> 1	2

💡 Key Point

& (AND) keeps only the common 1 bits.
| (OR) keeps all 1 bits from both numbers.
^ (XOR) flips bits where numbers differ.
~ (NOT) inverts all bits (watch out for negative values).
<< (Left Shift) doubles the number (a * 2^n).
>> (Right Shift) halves the number (a / 2^n).

📝 How to Get the Binary Value of a Character and Integer?

Get binary value of a char

Every character has an ASCII or Unicode value, which can be converted to binary:

				
					char letter = 'A';
int asciiValue = letter;  // Get ASCII value
Console.WriteLine($"ASCII of {letter}: {asciiValue}");
Console.WriteLine($"Binary of {letter}: {Convert.ToString(asciiValue, 2)}");

Output

				
					ASCII of A: 65
Binary of A: 1000001

Here, A (65 in decimal) is 1000001 in binary.

Get binary value of an Integer

To see the binary representation of an integer, you can use Convert.ToString(value, 2).

				
					int number = 5;
Console.WriteLine(Convert.ToString(number, 2));  // Output: 101

Here, 5 is represented as 101 in binary.

🎯 Bitwise Calculation Step-by-Step

Let’s take two numbers: 5 (0101) and 3 (0011). Now, let’s apply bitwise operations:

1️⃣ AND `(&)` - Bitwise AND Operator

The & (bitwise AND) operator in C# checks each bit of two numbers. It keeps 1 only if both numbers have 1 in that spot. If either number has 0, the result will be 0 in that place.

✅ If both bits are 1, the result is 1.
❌ If either bit is 0, the result is 0.

Rule: 1 & 1 = 1, otherwise 0
Example: 5 & 3

`(And)`				Integer
	1	0	1	`→ (5)`
&	0	1	1	`→ (3)`
	0	0	1	`→ (1)`

Each bit is compared:

0 & 0 = 0
1 & 0 = 0
0 & 1 = 0
1 & 1 = 1

				
					Console.WriteLine(5 & 3);  // Output: 1

2️⃣ `OR (|)` Bitwise OR Operator

The bitwise OR (|) operator compares each bit of two numbers and sets the result bit to 1 if at least one of the corresponding bits is 1. If both bits are 0, the result bit remains 0.

✅ If at least one bit is 1, the result is 1.
❌ If both bits are 0, the result is 0.

Rule:
- 1 | 0 = 1
- 1 | 1 = 1
Example: 5 | 3

`(OR)`				Integer
	1	0	1	`→ (5)`
\|	0	1	1	`→ (3)`
	1	1	1	`→ (7)`

Each bit is compared:

0 | 0 = 0
1 | 0 = 1
0 | 1 = 1
1 | 1 = 1

				
					Console.WriteLine(5 | 3);  // Output: 7

3️⃣ `XOR (^)` - Bitwise XOR Operator

The ^ (bitwise XOR) operator compares two numbers bit by bit and follows these simple rules:

✅ If the bits are different (0 and 1 or 1 and 0), the result is 1.
❌ If the bits are the same (0 and 0 or 1 and 1), the result is 0.

Rule:
- 1 ^ 1 = 0
- 1 ^ 0 = 1
Example: 5 ^ 3

`(XOR)`				Integer
	1	0	1	`→ (5)`
^	0	1	1	`→ (3)`
	1	1	0	`→ (6)`

Each bit is compared:

0 ^ 0 = 0
1 ^ 0 = 1
0 ^ 1 = 1
1 ^ 1 = 0

				
					Console.WriteLine(5 ^ 3);  // Output: 6

4️⃣ `NOT (~)` - Bitwise NOT Operator

The ~ (bitwise NOT) operator flips all the bits of a number:

✅ 0 becomes 1
❌ 1 becomes 0

Rule: Flips all bits
Example: ~5

				
					int a = 5;  //  00000000 00000000 00000000 00000101 (binary)
int result = ~a; 
Console.WriteLine(result); // Output: -6

Step-by-Step:

				
					   00000000 00000000 00000000 00000101  (5)
~  -----------------------------------
11111111 11111111 11111111 11111010  (-6 in two's complement)

👉 0 becomes 1
👉 1 becomes 0

Why is the result negative?

In C#, numbers are stored using two’s complement, so flipping all bits changes the sign of the number and adds -1.

For example:

~5 gives -6
~2 gives -3

5️⃣ `Left Shift (<<)` - Bitwise Left Shift Operator

The << (left shift) operator moves all bits to the left and fills the empty spaces with 0.

✅ Each shift left doubles the number.

Example

				
					int a = 5;  // 00000101 (binary)
int result = a << 1; // Shift left by 1
Console.WriteLine(result); // Output: 10

Step-by-Step:

				
					   00000101  (5)
<< 1
------------
00001010  (10)

👉 Every bit moves left, and a 0 is added on the right.
👉 Shifting left by 1 is like multiplying by 2.

More Examples:

				
					int x = 3;    // 00000011 (3)
Console.WriteLine(x << 2); // 12 (multiplied by 4)

💡 3 << 2 shifts left 2 times, multiplying by 2² = 4.

6️⃣ `Right Shift (>>)` - Bitwise Right Shift Operator

The >> (right shift) operator moves all bits to the right and removes bits on the right.

✅ Each shift right divides the number by 2.

Example

				
					int a = 8;  // 00001000 (binary)
int result = a >> 1; // Shift right by 1
Console.WriteLine(result); // Output: 4

Step-by-Step:

				
					   00001000  (8)
>> 1
------------
   00000100  (4)

👉 Each bit moves right, and the leftmost bit is filled based on the number type.
👉 Shifting right by 1 is like dividing by 2.

More Examples:

				
					int x = 16;    // 00010000 (16)
Console.WriteLine(x >> 2); // 4 (divided by 4)

💡 16 >> 2 shifts right 2 times, dividing by 2² = 4.

📌 Bitwise Operators in Action

Let’s see these operators in real code with output.

				
					using System;

class Program
{
    static void Main()
    {
        int a = 5, b = 3;

        Console.WriteLine($"a = {a}, b = {b}");
        Console.WriteLine($"a & b = {a & b}");  // AND
        Console.WriteLine($"a | b = {a | b}");  // OR
        Console.WriteLine($"a ^ b = {a ^ b}");  // XOR
        Console.WriteLine($"~a = {~a}");        // NOT
        Console.WriteLine($"a << 1 = {a << 1}"); // Left Shift
        Console.WriteLine($"a >> 1 = {a >> 1}"); // Right Shift
    }
}

🖥 Output:

				
					a = 5, b = 3
a & b = 1
a | b = 7
a ^ b = 6
~a = -6
a << 1 = 10
a >> 1 = 2
