Operators Precedence in C#

Precedence stands for the priority. Operator precedence determines the output of the expression.

Below are the operators accordings to categories.

Primary Operators

Primary operators has the highest precedence in C#. The associativity of the primary operators is from left to right. The primary operators are

Symbol	Operator	Description	Associativity
a++,a--	Post Increment and Post decrement	Increment or Decrement the original value of operand.	Left To Right
X.a	Accessing member of class.	accesing variable a with object X	Left To Right
X(a)-	Method Invocation	Calling method (a) with object X	Left To Right
X[a]	Element or variable access.	Accessing index 'a' with Array 'X'	Left To Right
new	Object Creation	Using new to create object of class.	Left To Right
typeof	type of datatype	To find the Datatype of Object ot Variable	Left To Right
checked, unchecked			Left To Right

Unary Operators

Unary Operators are the operators who work with only one operand. The operators has the right to left Associatiity. Below are the Unary Operators.

Symbol	Operator	Description	Associativity
+a,-a	Unary Plus and unary minus operator	Unary Plus and unary minus operator	right to left
++a,--a	Preincrement , predecrement	Preincrement , predecrement	right to left
!a	Logical Not	Reverse the value of the variable	right to left
~a	Bitwise Not	Reverse the value of the bit	right to left

Multiplicative Operators

Multiplicative Operators perform multiplication or division. They possess left to right associativity.

Symbol	Operator	Description	Associativity
*	Multiplication	Multiply two operands	left to right
/	Division	Divide two operands	left to right
%	Modulus	To calculate reminder of division	left to right

Additive Operators

Additive operators perform addition and subtraction. They posses left to right associativity.

Symbol	Operator	Description	Associativity
+	Addition	Addition of two numbers	Left To Right
-	Subtraction	Subtraction of two operands	Left To Right

Shift Operators

Shift Operators are used to shift the bits either right or left. Shift operators used with bitwise operators.

Symbol	Operator	Description	Associativity
<<	Left Shift	Shift one bit to the left	Left To Right
>	Right Shift	Shift one bit to right	Left To Right

Relational and Type Testing Operators

Relational and Type Testing Operators are used to compare two operands/variables and testing the operands/variables for diffrerent conditions i.e equality, greater than, less than etc.

Symbol	Operator	Description	Associativity
<	Less than	To test if one operator/variable is less than other	Left To Right
<=	Less than or Equal To	To test if one operator/variable is less than or equal to other	Left To Right
>	Greater Than	To test if one operator/variable is greater than the other	Left To Right
>=	Greater Thanor Equal to	To check whether one perator/variable is Greater Than or Equal to other	Left To Right

Equality Operators

To check whether two operands/Variables are equal or not , Equality operators are used. Equality operators have Left To Right Associativity.

Symbol	Operator	Description	Associativity
==	Is equal To	To Check whether one operand/Variable is equal to other	Left To Right
!=	Is not equal To	To Check whether one operand/Variable is not equal to other	Left To Right

Logical Operators

Logical operators used to compare two operand and the result/output of expression using logical operators is boolean format. They possess Left to Right Associativity. For example IF(a&&b==0) then...

Symbol	Operator	Description	Associativity
&&	Logical AND	Returns True when both the operands returns true	Left to Right
\|\|	Logical OR	Returns True when one of the operands returns true	Left to Right
^	Logical XOR	XOR operation between two operands	Left to Right
