- Yes add to collection is replaced with append item to collection
- Listusstates - change the variable type to system.collections.generic.list and select string under it
- Initializing a list ia done like this listusstates= new list(of string)
- Then use append item to collection for adding items to list
- In for each datatable I am not sure what you are trying to do but it looks mostly wrong
Hope this helps
Cheers
