删除SharePoint列表中的所有项目

Posted 2021-02-26

This will delete all items in a SharePoint list. Better than looping through a SPListItemCollection and doing a .delete();

SPList list = web.Lists[ListId];
SPListItemCollection splic = list.Items;
StringBuilder batchString = new StringBuilder();
batchString.Append("<?xml version="1.0" encoding="UTF-8"?><Batch>");
 
foreach (SPListItem item in splic)
{
        batchString.Append("<Method>");
        batchString.Append("<SetList Scope="Request">" + Convert.ToString(item.ParentList.ID) + "</SetList>");
        batchString.Append("<SetVar Name="ID">" + Convert.ToString(item.ID) + "</SetVar>");
        batchString.Append("<SetVar Name="Cmd">Delete</SetVar>");
        batchString.Append("</Method>");
}
 
batchString.Append("</Batch>");
SPContext.Current.Web.ProcessBatchData(batchString.ToString());
