在很多情况下，我们希望外部的应用可以得到位于SharePoint文档库中的文档信息。这时不妨试试通过调用WSS的Web服务来完成。
下面的示例代码完成了获取ID为1的文档（在文档库TestDL1中）的相对URL 和作者信息。
那ID是从哪里获取的呢？我想大家一定有很多方法啦。比如，文档库事件。
LabDb.Lists listService = new LabDb.Lists();
listService.Credentials = System.Net.CredentialCache.DefaultCredentials;
XmlDocument txd = new XmlDocument();
txd.LoadXml("<Query><Where><Eq><FieldRef Name=\"ID\" /><Value Type=\"Counter\">1</Value></Eq></Where></Query>");
XmlNode ndQuery = txd.SelectSingleNode("Query");
txd.LoadXml("<ViewFields><FieldRef Name=\"ID\" /><FieldRef Name=\"FileRef\" /><FieldRef Name=\"Author\"/></ViewFields>");
XmlNode ndViewFields = txd.SelectSingleNode("ViewFields");
string FileRef = "";
string Author = "";
try
{
XmlNode ndReturn = listService.GetListItems("TestDL1", null, ndQuery, ndViewFields, null, null);
XmlNamespaceManager nsmgr = new XmlNamespaceManager(ndReturn.OwnerDocument.NameTable);
nsmgr.AddNamespace("s", "uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882");
nsmgr.AddNamespace("dt", "uuid:C2F41010-65B3-11d1-A29F-00AA00C14882");
nsmgr.AddNamespace("rs", "urn:schemas-microsoft-com:rowset");
nsmgr.AddNamespace("z", "#RowsetSchema");
FileRef = ndReturn.SelectSingleNode("rs:data/z:row", nsmgr).Attributes["ows_FileRef"].Value;
FileRef = FileRef.Substring(FileRef.IndexOf("#") + 1);
Author = ndReturn.SelectSingleNode("rs:data/z:row", nsmgr).Attributes["ows_Author"].Value;
Author = Author.Substring(Author.IndexOf("#") + 1);
Console.WriteLine(FileRef);
Console.WriteLine(Author);
}
catch { }
listService.Credentials = System.Net.CredentialCache.DefaultCredentials;
XmlDocument txd = new XmlDocument();
txd.LoadXml("<Query><Where><Eq><FieldRef Name=\"ID\" /><Value Type=\"Counter\">1</Value></Eq></Where></Query>");
XmlNode ndQuery = txd.SelectSingleNode("Query");
txd.LoadXml("<ViewFields><FieldRef Name=\"ID\" /><FieldRef Name=\"FileRef\" /><FieldRef Name=\"Author\"/></ViewFields>");
XmlNode ndViewFields = txd.SelectSingleNode("ViewFields");
string FileRef = "";
string Author = "";
try
{
XmlNode ndReturn = listService.GetListItems("TestDL1", null, ndQuery, ndViewFields, null, null);
XmlNamespaceManager nsmgr = new XmlNamespaceManager(ndReturn.OwnerDocument.NameTable);
nsmgr.AddNamespace("s", "uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882");
nsmgr.AddNamespace("dt", "uuid:C2F41010-65B3-11d1-A29F-00AA00C14882");
nsmgr.AddNamespace("rs", "urn:schemas-microsoft-com:rowset");
nsmgr.AddNamespace("z", "#RowsetSchema");
FileRef = ndReturn.SelectSingleNode("rs:data/z:row", nsmgr).Attributes["ows_FileRef"].Value;
FileRef = FileRef.Substring(FileRef.IndexOf("#") + 1);
Author = ndReturn.SelectSingleNode("rs:data/z:row", nsmgr).Attributes["ows_Author"].Value;
Author = Author.Substring(Author.IndexOf("#") + 1);
Console.WriteLine(FileRef);
Console.WriteLine(Author);
}
catch { }
其中的关键是：
1、Query的编写
2、ViewFields的编写（可选，也可以给null，这样将显示所有）
3、XmlNamespace的添加
