我正在嘗試更新 SharePoint 列表，我在 Internet 上找到了一個代碼示例（Microsoft 官方文檔）所以這是代碼：using System;using Microsoft.SharePoint.Client;using SP = Microsoft.SharePoint.Client;namespace Microsoft.SDK.SharePointServices.Samples{ class UpdateListItem { static void Main() { string siteUrl = "http://MyServer/sites/MySiteCollection"; ClientContext clientContext = new ClientContext(siteUrl); SP.List oList = clientContext.Web.Lists.GetByTitle("Announcements"); ListItem oListItem = oList.Items.GetById(3); oListItem["Title"] = "My Updated Title."; oListItem.Update(); clientContext.ExecuteQuery(); } }}如果我在 visual studio 中復制/粘貼此代碼，則此行會出現錯誤：ListItem oListItem = oList.Items.GetById(3);List 不包含 Items 的定義，并且找不到可訪問的擴展方法“接受類型為‘List’的第一個參數”知道我必須做什么才能使用此代碼嗎？

您提供的用于更新列表項的代碼適用于SharePoint 2010. 對于較新的版本嘗試
ListItem oListItem = oList.GetItemById(3);
// Starting with ClientContext, the constructor requires a URL to the
// server running SharePoint.
ClientContext context = new ClientContext("http://SiteUrl");
// Assume that the web has a list named "Announcements".
List announcementsList = context.Web.Lists.GetByTitle("Announcements");
// Assume there is a list item with ID=1.
ListItem listItem = announcementsList.GetItemById(1);
// Write a new value to the Body field of the Announcement item.
listItem["Body"] = "This is my new value!!";
listItem.Update();
context.ExecuteQuery();
