Operator

Arithmetic Operators

Used for mathematical calculations.

+ : Addition
- : Subtraction
* : Multiplication
/ : Division
% : Modulus (remainder after division)
++ : Increment
-- : Decrement

Relational (Comparison) Operators

Used to compare two values.

== : Equal to
!= : Not equal to
> : Greater than
< : Less than
>= : Greater than or equal to
<= : Less than or equal to

Logical Operators

Used to perform logical operations.

&& : Logical AND
|| : Logical OR
! : Logical NOT

Bitwise Operators

Used for manipulating data at the bit level.

& : Bitwise AND
| : Bitwise OR
^ : Bitwise XOR (exclusive OR)
~ : Bitwise NOT (inversion)
<< : Left shift
>> : Right shift

Assignment Operators

Used to assign values to variables.

= : Assignment
+= : Add and assign
-= : Subtract and assign
*= " Multiply and assign
/= : Divide and assign
%= : Modulus and assign
&= : Bitwise AND and assign
|= : Bitwise OR and assign
^= : Bitwise XOR and assign
<<= : Left shift and assign
>>= : Right shift and assign

Null-Coalescing Operators

Handle null values in expressions.

?? : Null-coalescing operator (returns the left operand if it's not null, otherwise the right)
??= : Null-coalescing assignment (assigns the right operand only if the left operand is null)

Conditional (Ternary) Operator

Used to return one of two values depending on a condition.

?: : Ternary operator (condition ? first_expression : second_expression)

Type Operators

Used for working with types and type casting.

is : Checks if an object is compatible with a given type
as : Attempts to cast an object to a type, returns null if the cast fails
typeof : Returns the Type of a class or struct
sizeof : Returns the size in bytes of a value type
checked : Enables overflow checking for arithmetic operations
unchecked : Disables overflow checking for arithmetic operations

Index and Range Operators

[] : Access elements of an array or indexer
^ : Index from the end (C# 8.0+)
.. : Range operator (C# 8.0+)

Lambda Operator

Used in lambda expressions.

=> : Lambda operator

Member Access and Object Operators

Used to access members of objects and handle null reference types.

. : Member access operator (e.g., object.Property)
-> : Pointer-to-member access (unsafe context)
?. : Null-conditional operator (invokes a member only if the object isn't null)
[] : Index access

Pointer Operators (Unsafe Code)

Used in unsafe contexts for working with pointers.

* : Dereference pointer
& : Address-of operator (returns a pointer to the variable)
-> : Pointer member access
[] : Pointer index access

Other Special Operators

new : Creates objects and invokes constructors
sizeof : Returns the size in bytes of a value type
typeof : Returns the type of a class
checked : Enables overflow checking for arithmetic operations
unchecked : Disables overflow checking for arithmetic operations
await : Pauses an async method until a task is complete
yield : Returns values from an iterator method
default : Returns the default value for a type
nameof : Returns the name of a variable, type, or member as a string

Delegate and Event Operators

Used to work with delegates and events.

+= : Add a method to a delegate or event
-= : Remove a method from a delegate or event
