Data Types C# Language

When it comes to programming in C#, one of the fundamental concepts you need to grasp is data types. Data ty

pes specify the type of data that a variable can hold. They play a crucial role in memory allocation, data storage, and the operations you can perform on the data. In this post, we’ll explore the most common data types in C# and provide examples to help you understand their usage.

Integer Data Types:

• int

The int data type represents 32-bit signed integers. It is one of the most commonly used data types for storing whole numbers.

int age = 25;

• long

The long data type represents 64-bit signed integers and is used when you need to work with larger numbers.

long population = 8000000L;

Floating-Point Data Types:

• float

The float data type represents single-precision floating-point numbers. It is used for numbers with a decimal point.

float temperature = 98.6f;

• double

The double data type represents double-precision floating-point numbers, providing higher precision compared to float.

double pi = 3.14159265359;

Character Data Type:

• char

The char data type is used to store a single character or a Unicode character.

char grade = 'A';

Boolean Data Type:

• bool

The bool data type represents a Boolean value, which can be either true or false.

bool isWorking = true;

String Data Type:

• string

The string data type is used for storing sequences of characters, such as text.

string greeting = "Hello, World!";

Enumeration Data Type:

• enum

Enumerations are user-defined data types that consist of a set of named integral constants. They are useful for improving code readability.

enum DaysOfWeek
{
    Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday
}

DaysOfWeek today = DaysOfWeek.Wednesday;

Custom Data Types:

In C#, you can create custom data types using classes and structures. These allow you to define your own data structures and encapsulate data and behavior.

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}

Person person1 = new Person
{
    Name = "John",
    Age = 30
};
