Procedures and Functions in VB.NET Classes and Objects

In VB.NET, a class represents a blueprint for creating objects that have specific properties and methods. Procedures and functions are an integral part of classes and objects. In this page, we will discuss procedures and functions in VB.NET classes and objects.

Syntax

Procedures and functions have the same syntax in VB.NET. Here is the basic syntax:

<accessibility> Sub/Function <name> (Optional <parameters>) 
  ' Code block
End Sub/Function

• <accessibility> is an optional keyword that defines the accessibility of the procedure or function. It can be Public, Private, Protected, or Friend.
• Sub is used for procedures that do not return a value.
• Function is used for functions that return a value.
• <name> is the name of the procedure or function.
• <parameters> is an optional list of parameters to pass to the procedure or function.

Example

Here is an example of a class that contains a procedure and a function:

Public Class MyClass
    Public Sub MyProcedure()
        Console.WriteLine("This is a procedure.")
    End Sub

    Public Function MyFunction(ByVal x As Integer, ByVal y As Integer) As Integer
        Return x + y
    End Function
End Class

In this example, MyProcedure is a procedure that does not return a value and MyFunction is a function that returns an integer value.

Output

The output of the above example is:

This is a procedure.

Explanation

Procedures and functions are used to perform specific tasks in VB.NET applications. A procedure is a block of code that does not return a value, while a function is a block of code that returns a value.

In the example above, MyProcedure prints a message to the console, while MyFunction adds two integers and returns the result.

Use

Procedures and functions are used in VB.NET classes and objects to perform specific tasks. They allow you to organize your code into reusable blocks that can be called from anywhere in your program.

Important Points

• Procedures and functions have the same syntax in VB.NET.
• Procedures do not return a value, while functions return a value.
• Procedures and functions are used to perform specific tasks in VB.NET applications.

Summary

In this page, we discussed procedures and functions in VB.NET classes and objects. We covered the syntax, example, output, explanation, use, and important points of procedures and functions. By using procedures and functions in your VB.NET classes and objects, you can easily perform tasks and organize your code into reusable blocks.
