http://developers.de/blogs/bahro/archive/2014/12/03/remove-items-from-a-list-lt-t-gt-while-enumerating.aspxHere is a simple way to remove items from currently enumerated list.

Within while loop, every time items is removed decrease the index counter, otherwise increase the index. privateenCommunityServer 2008 SP1 (Build: 30619.63)
