  • 11/07/2009

If you want to assign Nothing to the optional parameter in VB.NET 10, it is just like to obvious now,

Sub Main()

    'Passing value for the optional parament _age

    MyFunc("Wriju", "wriju@contoso.com", 30)

    'No value is supplied for the optional parament _age

    MyFunc("Writam", "writam@contoso.com")

End Sub

Sub MyFunc(ByVal _name As String,

   ByVal _email As String,

           Optional ByVal _age As Integer? = Nothing)

    Console.WriteLine("Name={0}, Email={1}, Age={2}",

                      _name, _email, _age.ToString())

End Sub
