SharePoint Web Service系列:获取文档的属性信息

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  { }

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
