如何使用Web服务更新Sharepoint上载文档的属性？

Question

我正在尝试更新/编辑Sharepoint 2007上载文档的属性.

我的代码:

 Lists listService = new Lists();
 listService.PreAuthenticate = true;
 listService.Credentials = new NetworkCredential(username,password);
 listService.Url = "http://myserver/SiteName/_vti_bin/lists.asmx";

 string strBatch =

                   "<Method ID='1' Cmd='Update'> "
                   + " <Field Name='ID'>3</Field> "
                   + " <Field Name='Name'>Preeti</Field> "                 
                   + " </Method> ";

 XmlDocument xmlDoc = new System.Xml.XmlDocument();
 System.Xml.XmlElement elBatch = xmlDoc.CreateElement("Batch");
 elBatch.SetAttribute("OnError", "Continue");

elBatch.SetAttributeNode("UserName", "Preeti");
elBatch.InnerXml = strBatch;
XmlNode ndReturn = listService.UpdateListItems(ListName, elBatch);

MessageBox.Show(ndReturn.OuterXml);

以下解决方案提供自：http ://www.codeproject.com/KB/sharepoint/File_Shunter.aspx

但请注意，正如另一个答案中提到的，该字段的内部名称是必需的。

Web.Config 键

如果您选择这样做，请将以下内容添加到您的应用程序的 Web.config 中（仅作为示例，或者您可以简单地在代码中包含所需的值 [服务器、文档库、用户、域、密码等]） :

<configuration>
<appSettings>

<add key="SharePointServer" value=http://SP Portal/Site/>
<add key="DocLibrary" value="Doclib"/>
<add key="User" value="User"/>
<add key="Domain" value="Domain"/>
<add key="Pwd" value="Pwd"/>
<add key="GlobalSharedPath" value="D:\"/>
</appSettings>

代码：

Public Function WSSUpdateFile(ByVal sFileName As String, ByVal sSiteDoc As String, ByVal sTestCol As String) As String

        Dim sUser As String = ConfigurationManager.AppSettings("User")
        Dim sPwd As String = ConfigurationManager.AppSettings("Pwd")
        Dim sDomain As String = ConfigurationManager.AppSettings("Domain")
        Dim sFileIDinList As String
        Dim strBatch As String = ""
        sSiteDoc = Replace(sSiteDoc, "%20", " ")
        sSiteDoc = Replace(sSiteDoc, "\", "/")
        Dim sFinalFilePath As String
        Dim sSPURL As String = ConfigurationManager.AppSettings("SharePointServer")
        Dim sDocLib As String = ConfigurationManager.AppSettings("DocLibrary")
        Try
            Dim netAccess As System.Net.NetworkCredential = New System.Net.NetworkCredential(sUser, sPwd, sDomain)
            Dim listService As New SPLists.Lists
            listService.Url = sSPURL & "/_vti_bin/lists.asmx"
            listService.Credentials = netAccess
            sFileIDinList = sGetID(listService.Url, sDocLib, sFileName)
            If sFileIDinList <> "" Then
                sFinalFilePath = sSPURL & "/" & sDocLib & "/" & sFileName
                'Now we have FileID so update the list
                strBatch = "<Method ID='1' Cmd='Update'>" + _
                    "<Field Name = 'ID'>" & sFileIDinList & "</Field>" + _
                    "<Field Name = 'FileRef'>" & sFinalFilePath & "</Field>" + _
                    "<Field Name = 'TestCol'>" & sTestCol & "</Field>" + _
                    "</Method>"
                Dim xmlDoc = New System.Xml.XmlDocument
                Dim elBatch As System.Xml.XmlElement = xmlDoc.createelement("Batch")
                elBatch.InnerXml = strBatch
                Dim ndreturn As System.Xml.XmlNode = listService.UpdateListItems(sDocLib, elBatch)
            End If
            Return "TRUE"
        Catch ex As Exception
            Return ex.Message
        End Try
    End Function

Private Function sGetID(ByVal sURL As String, ByVal sListGUID As String, ByVal sFileName As String) As String
        Dim sUser As String = ConfigurationManager.AppSettings("User")
        Dim sPwd As String = ConfigurationManager.AppSettings("Pwd")
        Dim sDomain As String = ConfigurationManager.AppSettings("Domain")
        Dim netAccess As System.Net.NetworkCredential = New System.Net.NetworkCredential(sUser, sPwd, sDomain)
        Dim L As New SPLists.Lists
        L.Credentials = netAccess
        L.Url = sURL
        Dim xmldoc As XmlDocument = New XmlDocument
        Dim query As XmlNode = xmldoc.CreateNode(XmlNodeType.Element, "Query", "")
        query.InnerXml = "<OrderBy><FieldRef Name='Modified'  Ascending='False'></FieldRef></OrderBy>"""
        Try
            Dim caml As XmlNode = L.GetListItems(sListGUID, Nothing, query, Nothing, "1", Nothing)
            Dim id As String = caml.ChildNodes(1).ChildNodes(1).Attributes("ows_ID").Value
            Return id
        Catch ex As Exception
            Return ex.Message
        End Try
    End Function
