Multi-level Inheritance Example in VB.Net

Here, we will demonstrate the multilevel inheritance by creating three classes Sample1, Sample2, Sample3. Here, Sample1 will be the parent class for Sample2 and Sample2 will be the parent class for Sample3 class.

Program/Source Code:

The source code to demonstrate the multi-level inheritance is given below. The given program is compiled and executed successfully.

VB.Net code to implement the multi-level inheritance

'VB.net program to demonstrate the multi-level inheritance.

Module Module1
    Class Sample1
        Sub Fun1()
            Console.WriteLine("Sample1.Fun1() called")
        End Sub
    End Class
    Class Sample2
        Inherits Sample1
        Sub Fun2()
            Console.WriteLine("Sample2.Fun2() called")
        End Sub
    End Class
    Class Sample3
        Inherits Sample2
        Sub Fun3()
            Console.WriteLine("Sample3.Fun3() called")
        End Sub
    End Class

    Sub Main()
        Dim obj As New Sample3()
        obj.Fun1()
        obj.Fun2()
        obj.Fun3()
    End Sub

End Module

Output:

Sample1.Fun1() called
Sample2.Fun2() called
Sample3.Fun3() called
Press any key to continue . . .

Explanation:

In the above program, we created a module Module1. Here, we created three classes Sampl1, Sample2, and Sample3. Here, Sample1 is the parent class of Sample2 and Sample2 is the parent class of Sample3. Each class contains a method.

At last, we created a Main() function, it is the entry point for the program, here we created the object of Sample3 class, and called methods fun1(), fun2(), fun3(). All the methods will print a message on the console screen.
