C# Operators

PreviousNext

Operators are symbols that represent computations or operations on variables and values. C# supports a variety of operators, which can be categorized into the following types.

 

1. Arithmetic Operators

 

+ (Addition)

- (Subtraction)

* (Multiplication)

/ (Division)

% (Modulus, returns the remainder of a division)

int a = 10;
int b = 3;
int result = a + b;  // result = 13

 

2. Comparison Operators

 

== (Equal to)

!= (Not equal to)

< (Less than)

> (Greater than)

<= (Less than or equal to)

>= (Greater than or equal to)

int x = 5;
int y = 10;
bool isEqual = x == y;  // isEqual = false

 

3. Logical Operators

 

&& (Logical AND)

|| (Logical OR)

! (Logical NOT)

bool condition1 = true;
bool condition2 = false;
bool result = condition1 && condition2;  // result = false

 

4. Assignment Operators

 

= (Assignment)

+= (Addition assignment)

-= (Subtraction assignment)

*= (Multiplication assignment)

/= (Division assignment)

%= (Modulus assignment)

int num = 10;
num += 5;  // num = num + 5, so num is now 15

 

5. Increment and Decrement Operators

 

++ (Increment by 1)

-- (Decrement by 1)

int count = 5;
count++;  // count is now 6

 

6. Bitwise Operators

 

& (Bitwise AND)

| (Bitwise OR)

^ (Bitwise XOR)

~ (Bitwise NOT)

<< (Left shift)

>> (Right shift)

int a = 5;    // binary: 0101
int b = 3;    // binary: 0011
int result = a & b;  // result = 1 (binary: 0001)

 

7. Conditional Operator (Ternary Operator)

 

? : (Conditional expression)

int value = (x > y) ? x : y;  // if x > y, value = x; otherwise, value = y

 

These are the basic operators in C#. Understanding how to use them is fundamental for writing C# code.
