Collection was modified; enumeration operation may not execute

Question

I can\'t get to the bottom of this error, because when the debugger is attached, it does not seem to occur.

Collection was modified; enumeration operatio

Answer 1

Okay so what helped me was iterating backwards. I was trying to remove an entry from a list but iterating upwards and it screwed up the loop because the entry didn't exist anymore:

for (int x = myList.Count - 1; x > -1; x--)
{
    myList.RemoveAt(x);
}
