Class in VB.NET

What is a Class

A class defines a collection of encapsulated instance variables and methods, functions, optionally including implementations of those types and a constructor and destructor.

In this article, we will see how to use Visual Studio to add and work with classes using VB.NET.

Steps

You can add class by two ways, "directly go to the project menu and select Add New Item or Go the solution explorer Right click on project and chose Add New Item option", in Your Opened Project.

When you add a class to a project, Visual Basic Automatically generates the Class and End Class Statement so you can enter the code for the class between them.

As for displaying simple string in a console application like ("Welcome User"), you have to write this code between the newly added class body.

Public Class test

    Sub disp()

        Console.WriteLine("welcome user")

        Console.ReadLine()

    End Sub

End Class
And write this code in existing Module body .

Imports System.Console

Module Module1

    Sub Main()

        Dim obj As New test()

        obj.disp()

        Read()

    End Sub

End Module
After writing this code, build or debug the application. The output screen looks like following.
