Frequently used operators

For more information, see a C# or Java programming reference.

Operator category	Operator	Use	Description
Arithmetic	+	x + y	Adds x and y.
–	-	x - y	Subtracts y from x.
–	*	x * y	Multiplies x by y.
–	/	x / y	Divides x by y.
–	%	x % y	Returns the remainder of integer division of x and y.
Logical (Boolean and bitwise)	&	x & y	Evaluates both x and y and returns the logical conjunction ("AND") of their results. If x and y are integers, the logical conjunction is performed bitwise.
–	|	x | y	Evaluates x and y and returns the logical disjunction ("OR") of their results. If x and y are integers, the logical disjunction is performed bitwise.
–	^	x ^ y	Returns the exclusive or ("XOR") of their results. If x and y are integers, the exclusive or is performed bitwise.
–	!	!x	Evaluates x and returns the negation ("NOT") of the result. If x evaluates to false, it returns true. If x evaluates to true, it returns false.
–	~	~x	Evaluates x and returns the bitwise negation of the result. ~x returns a value where each bit is the negation of the corresponding bit in the result of evaluating x.
–	&&	x && y	Evaluates x. If the result is false, it returns false. Otherwise, it evaluates and returns the results of y. Note that if evaluating y would hypothetically have no side effects, the results are identical to the logical conjunction performed by the & operator.
–	||	x || y	Evaluates x. If the result is true, it returns true. Otherwise, it evaluates and returns the results of y. Note that if evaluating y would hypothetically have no side effects, the results are identical to the logical disjunction performed by the | operator.
–	( )	–	Used to group information.
String concatenation	+	x + y	Concatenates strings.
Relational	==	x == y	If x and y have the same value, it returns true. Otherwise, it returns false.
–	!=	x != y	Returns the logical negation of the operator ==. If x is not equal to y, it returns true. If x is equal to y, it returns false.
–	<	x < y	If x is less than y, it returns true. Otherwise, it returns false.
–	>	x > y	If x is greater than y, it returns true. Otherwise, it returns false.
–	<=	x <= y	If x is less than or equal to y, it returns true. Otherwise, it returns false.
–	>=	x >= y	If x is greater than or equal to y, it returns true. Otherwise, it returns false.
Member access	.	this.Value	Used to form long names.
Indexing	[ ]	–	Used to access array elements.
Conditional	?:	x ? y : z	If x is true, it returns y. Otherwise, it returns z.
Assignment	=	x = y	Assigns the value of y to x.
