C# Data Types | C# Tutorial for Beginners

 

 C# Data Types 

In C#, there are two main categories of data types: 

value types and reference types.

Value types are simple data types that store their value directly on the stack.

They include:

1. Numeric types: int, float, double, decimal, short, long, byte, sbyte, ushort, uint, and ulong.
2. Boolean type: bool.
3. Character type: char.
4. Enumerations: enum.

Reference types are more complex data types that store a reference to the value on the heap. 

They include:

1. Object type: object.
2. String type: string.
3. Arrays: int[], string[], etc.
4. Class types: custom classes that you define.

 

Here's an example of declaring and using some C# data types:

 

int age = 30;
double salary = 50000.50;
string name = "John Doe";
bool isEmployed = true;
char gender = 'M';
 
int[] numbers = { 1, 2, 3, 4, 5 };
object obj = new object();
 

age is an int, salary is a double, name is a string, isEmployed is a bool, and gender is a char. We're also declaring an array of integers, numbers, and an object obj.
