【问题描述】：

我有一个由 SSIS 条件拆分生成的列表。我尝试使用 C# 从列表中的每个项目中删除 sharepoint 站点但是，我执行 deleteobject() ；和context.ExecuteQuery()；它捕获以下错误：

[移动 SP SOQ [297]] 错误：ExecuteQuery SP Insert.Item 上的错误确实不存在。

您选择的页面包含不存在的项目。它可能已被其他用户删除。

        //Authentification au site SP page prncipale
        string url = Variables.ListURLdelete;
        ClientContext context = new ClientContext(url);
        context.AuthenticationMode = ClientAuthenticationMode.Default;
        context.Credentials = new NetworkCredential(Variables.WebServiceServerUserName, Variables.WebServiceServerPassword);

        Web web = context.Web;
      
        List SOQList = context.Web.Lists.GetByTitle(\"SOQ\");
        var item = SOQList.AddItem(new ListItemCreationInformation());
        if (Row.SOQENDDate >= 10)
        {

            if (!Row.Assignment_IsNull)
            {
                item[\"SOQAssignmentCode\"] = Row.Assignment;
            }
            //if (!Row.AssignmentLabel_IsNull)
            //{
            //    item[\"SOQAssignmentStatus\"] = Row.AssignmentLabel;
            //}
            //if (!Row.SOQTitle_IsNull)
            //{
            //    item[\"Title\"] = Row.SOQTitle;
            //}
            //Insertion dans SP
            // https://docs.microsoft.com/en-us/previous-versions/office/developer/sharepoint-2010/ee539976(v=office.14)
            try
            {
                Console.WriteLine(item);
                item.DeleteObject();
            }
            catch (Exception d)
            {
                ComponentMetaData.FireError(0, \"\", \"Error on Update Items SP Insert.\" + d.Message, \"\", 0, out vbool);
            }
            try
            {
                context.ExecuteQuery();
            }
            catch (Exception d)
            {
                ComponentMetaData.FireError(0, \"\", \"Error on ExecuteQuery SP Insert.\" + d.Message, \"\", 0, out vbool);
            }
        }

    }

可能是错误在列表 SOQList = context.Web.Lists.GetByTitle(\"SOQ\");?

// Authentification au site SP page prncipale
        string url = Variables.Test;
        ClientContext context = new ClientContext(url);
        context.AuthenticationMode = ClientAuthenticationMode.Default;
        context.Credentials = new NetworkCredential(Variables.WebServiceServerUserName, Variables.WebServiceServerPassword);

        Web web = context.Web;

        List SOQList = context.Web.Lists.GetByTitle("SOQ");

        if (Row.SOQStartDate >= 10 & !Row.SPID_IsNull)
        {
             This creates a CamlQuery that has a RowLimit of 100, and also specifies Scope="RecursiveAll"
             so that it grabs all list items, regardless of the folder they are in.
            CamlQuery query = CamlQuery.CreateAllItemsQuery();
            ListItemCollection items = SOQList.GetItems(query);


            context.Load(SOQList, list => list.ItemCount);
            context.ExecuteQuery();

            int startcount = SOQList.ItemCount;
            // delete du status
            ListItem listItem = SOQList.GetItemById(Row.SPID); -->OK

            try
            {
                listItem.DeleteObject();
                // SOQList.Update();

            }
            catch (Exception d)
            {
                ComponentMetaData.FireError(0, "", "Error on Update Items SP Insert." + d.Message, "", 0, out vbool);
            }
            try
            {
                context.ExecuteQuery();

            }
            catch (Exception d)
            {
                ComponentMetaData.FireError(0, "", "Error on ExecuteQuery SP Update." + d.Message, "", 0, out vbool);
            }
            context.Load(SOQList, list => list.ItemCount);
            context.ExecuteQuery();

            int endcount = SOQList.ItemCount;
            Console.WriteLine("Start: {0}  End: {1}", startcount, endcount);
        }
