Question

Suppose I have the following parent class defined:

Public Class Parent

    Public Property Prop1 As String = "MyDB1"

End Class

And I wish to inherit it, but want that property to have a different value for the child class.

I figured I could do it as follows:

Public Class Child
    Inherits Parent

    Public Sub New()
        MyBase.New()
        MyBase.Prop1 = "MyDB2"
    End Sub

End Class

But I was wondering if this was the best way to do this or if there is something like an Overridable property OR if this is just bad programming practice as a whole?

Thanks!

Based on your comment, here’s my opinion:

• If you are in control of the base class, make it Overridable if the intent is to have it’s value change based on business rule(s) of the derived type(s)
• If you are not in control of the base class, and you need to “override” the property, you can “hide” the base property; in C#, it would look something like new public int MyProperty { ... } but I’m not sure how this is accomplished in VB
• If all you need is for the property to return a different value, then what you’ve done seems fine
