.NET Operators

.NET operators include arithmetic and null-coalescing operators.

Introduction to .NET Operators

Operators in .NET are special symbols used to perform operations on operands. They are an essential part of the language, enabling you to carry out arithmetic, comparisons, logical operations, and more. Understanding operators is crucial for writing effective .NET code.

Arithmetic Operators

Arithmetic operators are used to perform mathematical operations such as addition, subtraction, multiplication, division, and modulus. These operators are straightforward and work with numerical data types.

Here is a list of basic arithmetic operators:

+ (Addition)
- (Subtraction)
* (Multiplication)
/ (Division)
% (Modulus)

Null-Coalescing Operator

The null-coalescing operator (??) is used to define a default value for nullable types or reference types. It is a convenient way to handle null values without needing multiple if-else statements.

It can be used in scenarios where you want to assign a default value if the current value is null.

Comparison Operators

Comparison operators are used to compare two values. These operators return a boolean result, indicating whether the comparison is true or false. They are essential in decision-making statements like if and loops.

Here are some common comparison operators:

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

Logical Operators

Logical operators are used to perform logical operations, often with boolean values. They are typically used in control flow statements to determine the logic of the conditions.

Here are the primary logical operators:

&& (Logical AND)
|| (Logical OR)
! (Logical NOT)
