You can not put different types inside a "generic list".

By Generic, do you refer to a Generic list? For example:


 Dim lstItems As List(Of String) = New List(Of String)


You can however create a class with ID, Date, Value as its properties and add it to a generic list.

Please clarify your question.

Maybe I did not put my question more clearly.
I need to update values in one list based on the values in the other

The ID is the join field and so is the Date, I want to update the Value field with that of the return
