generics - creating a new item

[Guest]

i am new to generics so...
if i have say

dim MySecondList as new BindingList (Of MyFirstThing)
dim MyFirstList as new BindingList (Of MySecondThing)

how can i instantiate a new item withing the list without knowing what Type
to create?
so i might have

sub Dostuff( bl as BindingList)
'create a new item in the bindinglist
i want to be able to say something like
bl.AddNewItem
and have the binding list instantiate the right sort of item and add it
to the list
so that if the list is MyFirstList it adds a new MyFirstThing
but if it is a MySecondList it adds a new MySecondThing

end sub

how do i do that?

thanks guy

BindingList has an AddNew method, is that what you're looking for?

Dim oFirstThing As Object
Dim oSecondThing As Object

oFirstThing = New MyFirstThing
oSecondThing = New MySecondThing

If TypeOf oFirstThing Is MyFirstThing Then
MyFirstList.Add(oFirstThing)

If TypeOf oSecondThing Is MySecondThing Then
MySecondList.Add(oSecondThing)
