如何使用Sharepoint Web Service从.NET获取文档列表？

using System;

using System.Xml.XPath;

public class SharePointHelper
{
    private string _url;
    private string _username;
    private string _password;

    public SharePointHelper(string url, string username, string password)
    {
        _url = url;
        _username = username;
        _password = password;
    }

    public List<string> GetDocumentList()
    {
        Lists lists = new Lists();
        lists.Url = _url;
        lists.Credentials = new System.Net.NetworkCredential(_username, _password);

        XmlNode listData = lists.GetListItems("Documents", null, null, null, "0", null, null);

        List<string> documentList = new List<string>();

        foreach (XmlNode node in listData.SelectNodes("//rs:data/z:row", GetXmlNamespaceManager(listData)))
        {
            string documentName = node.Attributes["ows_FileLeafRef"].Value;
            documentList.Add(documentName);
        }

        return documentList;
    }

    private XmlNamespaceManager GetXmlNamespaceManager(XmlNode node)
    {
        XmlNamespaceManager namespaceManager = new XmlNamespaceManager(node.OwnerDocument.NameTable);
        namespaceManager.AddNamespace("rs", "urn:schemas-microsoft-com:rowset");
        namespaceManager.AddNamespace("z", "#RowsetSchema");
        return namespaceManager;
    }
}

SharePointHelper sharePointHelper = new SharePointHelper("http://your_sharepoint_site/_vti_bin/lists.asmx", "username", "password");
List<string> documentList = sharePointHelper.GetDocumentList();

foreach (string documentName in documentList)
{
    Console.WriteLine(documentName);
}
