The "select case" in VB.Net

Here, we will select an option using "select case" by entering the choice from the user and then print the appropriate message on the console screen.

VB.Net code to demonstrate the use of 'select case'

The source code to demonstrate the use of "select case" is given below. The given program is compiled and executed successfully.

'VB.Net program to demonstrate the "select case".

Module Module1

    Sub Main()
        Dim choice As Char

        Console.WriteLine("############################")
        Console.WriteLine("     a: India")
        Console.WriteLine("     b: Australia")
        Console.WriteLine("     c: USA")
        Console.WriteLine("     d: UK")
        Console.WriteLine("############################")
        Console.Write("Select your country: ")
        choice = Char.Parse(Console.ReadLine())

        Select Case choice
            Case "a"
                Console.WriteLine("India")
            Case "b"
                Console.WriteLine("Australia")
            Case "c"
                Console.WriteLine("USA")
            Case "d"
                Console.WriteLine("UK")
            Case Else
                Console.WriteLine("Invalid choice")
        End Select
    End Sub

End Module

Output:

############################
     a: India
     b: Australia
     c: USA
     d: UK
############################
Select your country: a
India
Press any key to continue . . .

Explanation:

In the above program, we created a module Module1 that contains a Main() method. In the Main() method, we created a variable choice of Char type.

Console.WriteLine("############################")
Console.WriteLine("     a: India")
Console.WriteLine("     b: Australia")
Console.WriteLine("     c: USA")
Console.WriteLine("     d: UK")
Console.WriteLine("############################")
Console.Write("Select your country: ")
choice = Char.Parse(Console.ReadLine())

In the above code, we read a character for selection.

Select Case choice
    Case "a"
        Console.WriteLine("India")
    Case "b"
        Console.WriteLine("Australia")
    Case "c"
        Console.WriteLine("USA")
    Case "d"
        Console.WriteLine("UK")
    Case Else
        Console.WriteLine("Invalid choice")
End Select

In the above code, we used select case, here we defined multiple cases according to given choices. If we entered the wrong choice, which is not given then "Case Else" will be executed.
