Said that I have the following class
Class MyRootClass(Of T)
End Class
Class MySubClass1(Of T)
Inherits MyRootClass(Of T)
End Class
Hwo can I check, at runtime, if the type of the object 'Obj' (of type
MySubClass1), is a subclass of MyRootClass?
I don't want to care about the type used by the instance/declaration of
the generic class, they can be string, integer, other object.... this
is not important for my check
I need to check the type of the generic class, independently from the
type used by the various declaration/instance of my generic class.
Dim r As New MyRootClass(Of anything1)
Dim s1 As New MySubClass1(Of anything2)
'the following code return true, this is ok
s1.GetType.GetGenericTypeDefinition.BaseType.GetGe nericTypeDefinition
Is r.GetType.GetGenericTypeDefinition
'but, why the following code return FALSE?
s1.GetType.GetGenericTypeDefinition.IsSubclassOf(r .GetType.GetGenericTypeDefinition)
Why I'm unable to check inheritance of open generic type?
Thanks, adaway
