What's the best practice when you have to compare two large lists? My main list is 9000 objects long. I have to compare this to another list which might have 4000 objects in it.
Right now I'm doing it the WRONG way. For each row in the Main list i iterate through every item in the 4000 objects. As soon as I hit a match I return a true and that exits the iteration. This is still a very slow process. Both lists are dynamic. Any ideas on the right way to do this? Thanks, Nate
