在当前场景中，我试图将文档集从一个库复制到另一个库，问题是我不能使用 DocumentSet.Import，因为我只需要 docset 属性而不是内容。

此代码的 System.Update 中会引发异常。

private void CopyAgendaPointToRootSite(SPListItem agendaPointItem, string oldReasonReturned)
        {

            try
            {
                if (agendaPointItem != null)
                {
                    SPWeb currentSite = agendaPointItem.ParentList.ParentWeb;
                    SPSecurity.RunWithElevatedPrivileges(delegate()
                    {
                        using (SPSite site = new SPSite(currentSite.Site.RootWeb.Url))
                        {
                            using (SPWeb elevatedTargetWeb = site.OpenWeb())
                            {
                                SPList targetList = GetAgendaPointProposedTargetLibrary(agendaPointItem, elevatedTargetWeb);
                                SPDocumentLibrary targetDocumentLibrary = (SPDocumentLibrary)targetList;

                                SPContentTypeId targetCTId = targetList.ContentTypes.BestMatch(new SPContentTypeId(MeetingsCommon.Constants.CONTENTTYPES_AGENDAPOINTPROPOSED_ID));
                                DocumentSet documentSet = DocumentSet.GetDocumentSet(agendaPointItem.Folder);
                                if (documentSet != null)
                                {
                                    string strAgendaPointTitle = agendaPointItem[MeetingsCommon.Constants.FIELDS_AGENDAPOINTTITLENL_NAME] +
                                        " / " + agendaPointItem[MeetingsCommon.Constants.FIELDS_AGENDAPOINTTITLEFR_NAME];

                                    SPListItemCollection colProposedItems = FindAgendaPointProposedItem((SPDocumentLibrary)targetList, documentSet.Item.Name);
                                    if (colProposedItems.Count > 0)
                                        throw new Exception(string.Format(HelperFunctions.GetResourceString(

                throw;
            }

        }

我修复了它做以下

 DocumentSet docSetCreated = DocumentSet.Create(targetList.RootFolder, agendaPointItem.Name, targetCTId, new Hashtable(), true);
                                        int  listItemId = docSetCreated.Item.ID;
                                        SPListItem listItem = targetList.GetItemById(listItemId);

显然在创建文档集之后，我不能再使用该对象的列表项了，我需要获得一个新的
