.NET Data Types

.NET data types include int string and bool with type inference.

Introduction to .NET Data Types

In .NET, data types are a fundamental concept that define the type of data a variable can hold. Understanding data types is crucial for effective programming in .NET, as it ensures that variables are used correctly and efficiently. This guide will cover basic data types such as int, string, and bool, along with an introduction to type inference.

Integer Data Type (int)

The int data type is used to store 32-bit signed integers. It is one of the most commonly used data types in .NET for numerical operations.

Here's how you can declare an int variable:

In this example, we declare a variable named age and initialize it with the value 30.

String Data Type (string)

The string data type is used to store sequences of characters. It is widely used for working with text in .NET applications.

Here's an example of declaring a string variable:

In this example, a variable named name is declared and initialized with the text "John Doe".

Boolean Data Type (bool)

The bool data type is used to represent Boolean values, which can be either true or false. This type is particularly useful for conditional statements and logic operations.

Here's how to declare a bool variable:

In this example, we declare a variable called isStudent and set it to true, indicating a positive Boolean condition.

Type Inference in .NET

.NET supports type inference, which allows the compiler to automatically detect the type of a variable based on the assigned value. This feature simplifies code by reducing the need for explicit type declarations.

Here's an example of type inference:

In the examples above, the var keyword is used to declare variables. The compiler infers that score is an int and message is a string based on the assigned values.
