Question

我是sharepoint的新手，我正在尝试从sharepoint检索的项目列表中构建父母及其各自子女的树视图列表。在下面的代码中，我使用＆＃34; ID＆＃34; fieldvalue用于标识项目和＆＃34; parentleafname＆＃34; lookupvalue尝试确定此项是否具有父项。看起来虽然是＆＃34; ID＆＃34;来自＆＃34; parentleafname＆＃34;的查找值是相同的。如何从返回的列表中的项目中获取父ID？

   private ListItemCollection GetList(string listName)
        {
            var web = _sharePointContext.Web;
            Microsoft.SharePoint.Client.List list = web.Lists.GetByTitle(listName);

            var query = new CamlQuery();

            query.ViewXml = "<View Scope=\"RecursiveAll\"> " +
                            "< Query >" +
                            "< OrderBy >" +
                            "< FieldRef Name = 'ID' />" +
                            "</ OrderBy >" +
                            "</ Query >" +
                            "</View>";

            query.FolderServerRelativeUrl = "/lists/" + listName;
            ListItemCollection folders = list.GetItems(query);

            _sharePointContext.Load(list);
            _sharePointContext.Load(list.Fields);
            _sharePointContext.Load(folders, fs => fs.Include(
                fi => fi["Title"],
                fi => fi["DisplayName"],
                fi => fi["FileLeafRef"],
                fi => fi["ParentLeafName"],
                fi => fi["ID"],
                fi => fi["ContentTypeId"]
                ));
            _sharePointContext.ExecuteQuery();


            return folders;
        }

这不是解决此问题的最佳方法，但它确实有效。我设法使用父文件夹属性ServerRelativeUrl，可以为列表中的每个项检索该属性，如下所述：

然后，我使用此类从路径（ServerRelativeURL）构建父/子层次结构：
