C# Operators

C# Operators — including arithmetic, logical, comparison, assignment, bitwise, and more — with examples and descriptions:

1. Arithmetic Operators

Operator	Name	Example	Description
`+`	Addition	`a + b`	Adds two operands
`-`	Subtraction	`a - b`	Subtracts second operand from first
`*`	Multiplication	`a * b`	Multiplies operands
`/`	Division	`a / b`	Divides numerator by denominator
`%`	Modulus	`a % b`	Returns remainder of division
`++`	Increment	`a++` or `++a`	Increases value by 1
`--`	Decrement	`a--` or `--a`	Decreases value by 1

2. Assignment Operators

Operator	Example	Equivalent To	Description
`=`	`a = 5`	—	Assigns value
`+=`	`a += 2`	`a = a + 2`	Adds and assigns
`-=`	`a -= 2`	`a = a - 2`	Subtracts and assigns
`*=`	`a *= 3`	`a = a * 3`	Multiplies and assigns
`/=`	`a /= 2`	`a = a / 2`	Divides and assigns
`%=`	`a %= 2`	`a = a % 2`	Modulus and assigns

3. Comparison / Relational Operators

Operator	Example	Description
`==`	`a == b`	Returns `true` if values are equal
`!=`	`a != b`	Returns `true` if not equal
`>`	`a > b`	Greater than
`<`	`a < b`	Less than
`>=`	`a >= b`	Greater than or equal to
`<=`	`a <= b`	Less than or equal to

4. Logical Operators

Operator	Name	Example	Description
`&&`	AND	`a && b`	True if both are true
`		`	OR
`!`	NOT	`!a`	Inverts the Boolean value

5. Bitwise Operators

Operator	Name	Example	Description
`&`	AND	`a & b`	Performs bitwise AND
`	`	OR	`a
`^`	XOR	`a ^ b`	Performs bitwise exclusive OR
`~`	NOT	`~a`	Inverts all bits
`<<`	Left Shift	`a << 2`	Shifts bits to the left
`>>`	Right Shift	`a >> 2`	Shifts bits to
