Removing Items in a List While Iterating Through It with For Each Loop

Question

I have a list named NeededList I need to check each item in this list to see if it exists in my database. If it does exist in the database I need to remove it

Answer 1

The contents of an array (or anything else you can fast enumerate with For Each can not be modified with a For Each loop. You need to use a simple For loop and iterate through every index.

Hint: Because you'll be deleting indexes, I suggest starting at the last index and work your way toward the first index so you don't skip over one every time you delete one.
