如何使用LINQ查询更新列表视图（sharepoint 2007）：

SPList taskList = SPContext.Current.Web.Lists["List1"];
SPList branchList = SPContext.Current.Web.Lists["List2"];

var taskListItems = from SPListItem tItem in taskList.Items
                    join SPListItem IItem in branchList.Items on tItem["Branch"].ToString().Split(new string[]{";#"},StringSplitOptions.None)[1] equals IItem.Title.ToString()
                    where IItem.Title.ToString() == "Kazan"
                    select tItem.Title;

SharePoint 2007不支持Linq（.net 3.5）开箱即用，我猜您使用的是模板吗？

您需要按照指南进行设置：

然后，本指南可能会帮助您构建查询
