Correct way to delete all SPListItems
Today while coding a Sharepoint timer job I needed to clean my SPList.
I tried common ways of deleting using "foreach" and "for i++ ..." but I got the error. I couldn't delete list and create it again in timer job because of custom views. As usually for SharePoint solution is not ordinary 🙂
So, as it turned out, correct syntax of deleting all SPListItems is using "for i--":
for (int i = list.Items.Count - 1; i >= 0; i--) { list.Items.Delete(i); }
