In this article We will see that how to define function Overloading and how to use Function Overloading in VB.NET.

In method overloading, multiple method having  the same name but different type of argument. sometimes our reqirement needs us to be able to create more function with same names this allows programer to provide easiness to the user by allowing user to use single name for different purposes.

For example:

Public Overloads Sub area(ByVal r)

Public Overloads Sub area(ByVal length, ByVal width)

In the above example there are two method which has the same name but use for different purpose one define the area of circle and other define the area of rectangle. Both method have the different parameter.

The following code define the Function overloading:

Imports System

Module Module1

    Class overload

        Dim r As Double

        Public Overloads Sub area(ByVal r) // define the function name area

            Console.Write("Area of the Circle :")

            Console.WriteLine(1 / 3 * 3.14 * r * r * r)

        End Sub

        Dim length As Integer

        Dim width As Integer

        Public Overloads Sub area(ByVal length, ByVal width) // define the function area

            Console.Write(" Area of the Rectangle :")

            Console.WriteLine(length * width)

        End Sub


    End Class


    Sub Main()


        Dim r As New overload()  // creating object of the class overload


        r.area(4, 5)


    End Sub

End Module
