Question

I have an abstract class that has two constructors. When another class inherits this class, it appears that I have to declare contructors with identical signatures as the ones in the base class. This seems a bit redundant to me. Is there a way to have Sub New(Parameter as MyClass) in my base class and have this become the default constructor signature unless the derived class includes it in its definition?

Edit for clarity: I was hoping it was implied that I do not want to have to create a constructor in the derived class that calls the base class. I would like to be able to do this:

Mustinherit Class MyBase

  Sub New(MyParam As String)

  End Sub

End Class

Class MyDerived
  Inherits MyBase

End Class

Notice now the derived class doesn’t call the base?

Answer 1

In VB.Net you use:

MyBase.New(args)

Inside your constructors method body, no extra verbiage is used on the constructors/method signature.
