Format
list.RemoveAll(Item1,Item2,...)
Returns
Number of items removed.
Args
One or more items to remove entirely from the list.
Removes all copies of the specified items from the list. If an argument is itself a list, each item contained in it will be removed.
This is basically a faster version of the statement while(list.Remove(Item1,Item2,...)) with an empty code block. For large lists this might be a big improvement because the list doesn’t have to be traversed every time.
