Nested namespace in VB.Net

Here, we will create a user-defined namespace that contains a nested namespace. Here, outer and inner namespace will contain classes.

Program/Source Code:

The source code to demonstrate the nested namespace is given below. The given program is compiled and executed successfully.

VB.Net code to demonstrate the example of nested namespace

'VB.net program to demonstrate the nested namespace.

Namespace MathNamespace
    Class AritheMatic
        Sub Add(ByVal num1 As Integer, ByVal num2 As Integer)
            Console.WriteLine("Addition is: {0}", num1 + num2)
        End Sub

        Sub Subtract(ByVal num1 As Integer, ByVal num2 As Integer)
            Console.WriteLine("Subtraction is: {0}", num1 - num2)
        End Sub
    End Class

    Namespace Nested
        Class Fact
            Sub CalculateFactorial(ByVal num As Integer)
                Dim fact As Integer = 1

                For i = num To 1 Step -1
                    fact = fact * i
                Next
                Console.WriteLine("Factorial is: {0}", fact)
            End Sub
        End Class

    End Namespace
End Namespace

Module Module1

    Sub Main()
        Dim airth As New MathNamespace.AritheMatic
            Dim fact As New MathNamespace.Nested.Fact

            airth.Add(5, 10)
            airth.Subtract(50, 15)

            fact.CalculateFactorial(7)
        End Sub
        
End Module

Output

Addition is: 15
Subtraction is: 35
Factorial is: 5040

Explanation

In the above program, we created a namespace MathNamespace that contains a nested namespace nested. Both namespaces contain classes. And each class contains methods.

After that, we created a module Module1 that contains the main() method, the main() method is the entry point for the program. Here, we created the object of both classes and then called methods to perform mathematical operations.
