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.ListslistService = new LabDb.Lists();
listService.Credentials
= System.Net.CredentialCache.DefaultCredentials;

XmlDocumenttxd
= new XmlDocument();
txd.LoadXml(
" <Query><Where><Eq><FieldRefName=\ " ID\ " /><ValueType=\ " Counter\ " >1</Value></Eq></Where></Query> " );
XmlNodendQuery
= txd.SelectSingleNode( " Query " );
txd.LoadXml(
" <ViewFields><FieldRefName=\ " ID\ " /><FieldRefName=\ " FileRef\ " /><FieldRefName=\ " Author\ " /></ViewFields> " );
XmlNodendViewFields
= txd.SelectSingleNode( " ViewFields " );
string FileRef = "" ;
string Author = "" ;
try
{
XmlNodendReturn
= listService.GetListItems( " TestDL1 " , null ,ndQuery,ndViewFields, null , null );
XmlNamespaceManagernsmgr
= 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
