Overload the property in VB.Net

Here, we will create a class and implement default property to set and get values of data members, and we also created one more property to searched the specified county in the country list.

Program/Source Code:

The source code to overload the property is given below. The given program is compiled and executed successfully.

Class Sample
    Dim countries(5) As String
    Dim size As Integer
    Default Public Property country(ByVal index As Integer) As String
        Get
            Return countries(index)
        End Get
        Set(ByVal value As String)
            size = index
            countries(index) = value
        End Set
    End Property

    Public ReadOnly Property Search(ByVal val As String) As Integer
        Get
            For i = 0 To size Step 1
                If countries(i) = val Then
                    Return i
                End If
            Next
            Return -1
        End Get
    End Property
End Class
Module Module1
    Sub Main()
        Dim S As New Sample()

        S(0) = "India"
        S(1) = "Australia"
        S(2) = "America"
        S(3) = "Canada"

        Console.WriteLine("Country Names:")
        For i = 0 To 3 Step 1
            Console.WriteLine(vbTab & S(i))
        Next

        If (S.Search("America") <> -1) Then
            Console.WriteLine("America found in the country list")
        Else
            Console.WriteLine("America is not found in the country list")
        End If
    End Sub
End Module

Output:

Country Names:
        India
        Australia
        America
        Canada
America found in the country list

Explanation:

In the above program, we created a class Sample that contains a data member countries. Here, countries is an array of strings. Here, we implemented a default property to set and get the values of the countries array. Then we also implemented one more property to search the country name from the list of countries, here if the country name is found then it will return the index of country name otherwise it will return -1.

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 an object of the Sample class and then set the values of data members using object name with specified index and then print the country names on the console screen. After that, we searched the item from the list and print the appropriate message on the console screen.
