Do not call SPListItemVersion.Delete to delete multiple versions

When you delete multiple versions of a list item, use the DeleteByID() method; do not use the Delete() method. You will experience performance problems if you delete each SPListItemVersion object from an SPListItemVersionCollection object.

TypeName DoNotUseSPListItemVersionDelete
Severity CriticalWarning
Type Assembly

The recommended practice is to create an array that contains the ID properties of each version and then delete each version by using the SPListItemVersionCollection.DeleteByID method.

SPSite site = new SPSite("site url");
SPWeb web = site.OpenWeb();
SPList list = web.Lists["custom list name"];
SPListItem item = list.GetItemById(1);
SPFile file = web.GetFile(item.Url);
SPFileVersionCollection collection = file.Versions;
ArrayList idList = new ArrayList();
foreach (SPFileVersion ver in collection)
foreach (int verID in idList)
   catch (Exception ex)
