方法1(快速,以理解,可以封装):
SPList spListQuestion = spWeb.Lists["Question List"]; for (int i = spListQuestion.Items.Count - 1; i >= 0; i--) { spListQuestion.Items[i].Delete(); }
方法2(繁琐):
SPList spListQuestion = spWeb.Lists["Question List"]; string sDIDTitle = spListQuestion.Fields["DID"].InternalName; SPQuery spQuery = new SPQuery(); spQuery.Query = "" + "" + spDocItem.ID.ToString() + ""; SPListItemCollection collListItems = spListQuestion.GetItems (spQuery); for (int i = 0; i < collListItems.Count; i++) { string ID = collListItems[i]["ID"].ToString(); SPItem spItem = spListQuestion.GetItemById (Int16.Parse (ID) ); spItem.Delete(); }
方法3(推荐):
SPList targetList = null; try { targetList = currentWeb.GetList (currentWeb.ServerRelativeUrl.TrimEnd ('/') + listUrl); } catch { } if (targetList != null) { StringBuilder sbDelete = new StringBuilder(); sbDelete.Append ("<?xml version="1.0" encoding="UTF-8"?><Batch>"); foreach (SPItem item in targetList.Items) { if (item["Title"] != null) { sbDelete.Append ("<Method>"); sbDelete.Append ("<SetList Scope="Request">" + targetList.ID + "</SetList>"); sbDelete.Append ("<SetVar Name="ID">" + Convert.ToString (item.ID) + "</SetVar>"); sbDelete.Append ("<SetVar Name="Cmd">Delete</SetVar>"); sbDelete.Append ("</Method>"); } } sbDelete.Append ("</Batch>"); try { currentWeb.ProcessBatchData (sbDelete.ToString() ); targetList.Update(); } catch (Exception ex) { } }
