SharePoint自帶了WebService，通常情況下是跨服務器的訪問，因為同一服務器上不同網站可以簡單的通過提升權限代碼就可以訪問數據。

以跨服務器讀取某個list為例，對項目添加“http://<server-url>/_vti_bin/Lists.asmx”和“http://<server-url>/_vti_bin/SiteData.asmx”的引用。

對兩個引用的命名分別為ListService和SiteDataService

//訪問列表庫，通過CAML查詢返回的是一個XML文件，不需要解析直接給DataSet類型賦值

?public static DataSet GetItems()

??????? {
??????????? ListService.Lists listsWS = new ListService.Lists();
??????????? //listsWS.Credentials = System.Net.CredentialCache.DefaultCredentials; //該句在編譯環境可以代替下一句，但是跨服務器應用肯定要用下一句
??????????? listsWS.Credentials = new NetworkCredential(用戶名, 密碼, 域名);
??????????? XmlDocument doc = new System.Xml.XmlDocument();
??????????? doc.LoadXml("<Document><Query><Where>CAML</Where></Query><ViewFields /><QueryOptions /></Document>");
??????????? XmlNode listQuery = doc.SelectSingleNode("//Query");
??????????? XmlNode listViewFields = doc.SelectSingleNode("//ViewFields");
??????????? XmlNode listQueryOptions = doc.SelectSingleNode("//QueryOptions");

??????????? Guid g = GetWebID();
????????? ?
??????????? XmlNode items = listsWS.GetListItems("ListName", string.Empty, listQuery, listViewFields, string.Empty, listQueryOptions, g.ToString());

??????????? NameTable nt = new System.Xml.NameTable();
??????????? XmlNamespaceManager nsMgr = new XmlNamespaceManager(nt);
??????????? nsMgr.AddNamespace("w", "http://schemas.microsoft.com/office/word/2003/2/wordml");
??????????? XmlNode y = items.SelectSingleNode("*", nsMgr);
??????????? DataSet ds = new DataSet();
??????????? if (y != null)
??????????? {
??????????????? XmlReader xmlReader = new XmlTextReader(y.InnerXml, XmlNodeType.Element, null);
??????????????? ds.ReadXml(xmlReader);
??????????? }
??????????? return ds;
??????? }

??????? private static Guid GetWebID()
??????? {
??????????? SiteDataService.SiteData siteDataWS = new sinopecSiteData.SiteData();
??????????? siteDataWS.Credentials = new NetworkCredential(用戶名, 密碼, 域名);
??????????? SiteDataService._sWebMetadata webMetaData;
??????????? SiteDataService._sWebWithTime[] arrWebWithTime;
??????????? SiteDataService._sListWithTime[] arrListWithTime;
??????????? SiteDataService._sFPUrl[] arrUrls;
??????????? string roles; string[] roleUsers; string[] roleGroups;?????
??????????? uint i = siteDataWS.GetWeb(out webMetaData, out arrWebWithTime, out arrListWithTime, out arrUrls, out roles, out roleUsers, out roleGroups);
??????????? Guid g = new Guid(webMetaData.WebID);
??????????? return g;

??????? }

?以上代碼要特別注意兩點：

1。身份驗證。對web引用可以直接在webconfig里面直接修改地址，相應的修改代碼中的驗證登錄信息就可以，建議都弄到配置文件里，方便統一維護。

2。解析XML。
