Operators :

C language Operators - C++ Language Operators - In C#, an operator is a program element that is applied to one or more operands in an expression or statement. Operators that take one operand, such as the increment operator ( ++) or new, are referred to as unary operators. Operators that take two operands, such as arithmetic operators ( + , - , * , / ), are referred to as binary operators. One operator, the conditional operator ( ? : ), takes three operands and is the sole ternary operator in C#.

Primary Operators :

Expression	Description
x.y	Member access
x?.y	Conditional member access
f(x)	Method and delegate invocation
a[x]	Member access
x.y	Array and indexer access
a?[x]	Conditional array and indexer access
x++	Post-increment
x--	Post-decrement
new T(...)	Object and delegate creation
new T(...){...}	Object creation with initializer.
new {...}	Anonymous object initializer.
new T[...]	Array creation.
typeof(T)	Obtain System.Type object for T
checked(x)	Evaluate expression in checked context
unchecked(x)	Evaluate expression in unchecked context
default (T)	Obtain default value of type T
delegate {}	Anonymous function (anonymous method)

Unary Operators :

Expression	Description
+x	Identity
-x	Negation
!x	Logical negation
~x	Bitwise negation
++x	Pre-increment
--x	Pre-decrement
(T)x	Explicitly convert x to type T

Multiplicative Operators :

Expression	Description
*	Multiplication
/	Division
%	Remainder

Additive Operators :

Expression	Description
x + y	Addition, string concatenation, delegate combination
x - y	Subtraction, delegate removal

Shift Operators :

Expression	Description
x << y	Shift left
x >> y	Shift right

Relational and Type Operators :

Expression	Description
x < y	Less than
x > y	Greater than
x <= y	Less than or equal
x >= y	Greater than or equal
x is T	Return true if x is a T, false otherwise
x as T	Return x typed as T, or null if x is not a T

Equality Operators :

Expression	Description
x == y	Equal
x != y	Not equal

Logical, Conditional, and Null Operators :

Category	Expression	Description
Logical AND	x & y	Integer bitwise AND, Boolean logical AND
Logical XOR	x ^ y	Integer bitwise XOR, boolean logical XOR
Logical OR	x | y	Integer bitwise OR, boolean logical OR
Conditional AND	x && y	Evaluates y only if x is true
Conditional OR	x || y	Evaluates y only if x is false
Null coalescing	x ?? y	Evaluates to y if x is null, to x otherwise
Conditional	x ? y : z	Evaluates to y if x is true, z if x is false

Assignment and Anonymous Operators :

Expression	Description
=	Assignment
x op= y	Compound assignment. Supports these operators: +=, -=, *=, /=, %=, &=, |=, ^=, <<=, >>=
(T x) => y	Anonymous function (lambda expression)
