Question

I’m having issues implementing an interface which vb.net is not picking it up through inheritance, not sure its possible but i believe there should be a way

Public Interface ITest

    Sub SomeMethod()

End Interface

Public Class Test
    Inherits OtherClass
    Implements ITest

End Class

Public Class OtherClass

    Sub SomeMethod()

    End Sub

End Class

Class “OtherClass” is on another assembly where that ITest interface does not live and I cant have it there. However, with c# you are not forced to use the Implements keyword on each method, c# looks through the name and signatures.

So basically, Im getting the “Missing implementation of members” and what I was expecting was to be able to compile fine since Im inheriting a class that has the same methods defined on the interface.

Is this possible?

Answer 1

For OtherClass to implement the ITest interface, it needs a reference to that ITest interface.

Once you have it referenced, then your OtherClass would look like this:

Public Class OtherClass
  Implements ITest

  Sub SomeMethod() Implements ITest.SomeMethod

  End Sub

End Class
