SharePoint 更新列表项

Question

我正在尝试更新 SharePoint 列表，我在 Internet 上找到了一个代码示例（Microsoft 官方文档）所以这是代码：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 中复制/粘贴此代码，则此行会出现错误：ListItem oListItem = oList.Items.GetById(3);List 不包含 Items 的定义，并且找不到可访问的扩展方法“接受类型为‘List’的第一个参数”知道我必须做什么才能使用此代码吗？

您提供的用于更新列表项的代码适用于SharePoint 2010. 对于较新的版本尝试

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();
