Overloading binary multiplication (*) operator in VB.Net

Here, we will overload the binary multiplication (*) operator with a class to apply multiplication operations between two objects to get the remainder.

Program/Source Code:

The source code to overload binary multiplication (*) operator is given below. The given program is compiled and executed successfully.

VB.Net code to overload binary multiplication (*) operator

'VB.net program to overload binary multiplication "*" operator.

Class Sample
    Dim num1 As Integer
    Dim num2 As Integer

    Sub SetValues(ByVal n1 As Integer, ByVal n2 As Integer)
        num1 = n1
        num2 = n2
    End Sub

    Public Shared Operator Mod(ByVal S1 As Sample, ByVal S2 As Sample) As Sample
        Dim temp As New Sample()
        temp.num1 = S1.num1 * S2.num1
        temp.num2 = S1.num2 * S2.num2
        Return (temp)
    End Operator

    Sub PrintValues()
        Console.WriteLine(vbTab & "Num1: {0}", num1)
        Console.WriteLine(vbTab & "Num2: {0}", num2)
    End Sub

End Class

Module Module1
    Sub Main()
        Dim obj1 As New Sample()
        Dim obj2 As New Sample()
        Dim obj3 As New Sample()

        obj1.SetValues(6, 4)
        obj2.SetValues(3, 7)

        obj3 = obj1 Mod obj2

        Console.WriteLine("Obj1: ")
        obj1.PrintValues()
        Console.WriteLine("Obj2: ")
        obj2.PrintValues()
        Console.WriteLine("Obj3: ")
        obj3.PrintValues()
    End Sub
End Module

Output:

Obj1:
        Num1: 6
        Num2: 4
Obj2:
        Num1: 3
        Num2: 7
Obj3:
        Num1: 18
        Num2: 28
Press any key to continue . . .

Explanation:

In the above program, we created a class Sample that contains two methods SetValues(), PrintValues() to set and print the values of data members of the class. Here, we implemented one more method to overload binary multiplication (*) operator.

After that, we created a module Module1 that contains the Main() method, the Main() method is the entry point for the program. And, we created the two objects of the Sample class and then perform the binary multiplication operation between two objects and return the multiplication that will be assigned to the third object.
