Wie aktualisiere ich die Eigenschaften hochgeladener Dokumente auf Sharepoint mithilfe von Webdiensten?

Question

Ich versuche 2007.

Mein Code zu aktualisieren/bearbeiten Eigenschaften von hochgeladenes Dokument auf Sharepoint:

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);

Error error: "Ein oder mehrere Feldtypen sind nicht richtig installiert. Gehen Sie zur Listeneinstellungsseite, um diese Felder zu löschen".

Die folgende Lösung aus zur Verfügung gestellt: http://www.codeproject.com/KB/sharepoint/File_Shunter.aspx

Hinweis jedoch, wie in der anderen Antwort erwähnt, ist der interne Name des Feldes erforderlich.

Web.Config Keys

Wenn Sie wählen, um mit der für Ihre Anwendung auf die Web.config hinzugefügt folgenden (für dieses Beispiel nur, alternativ können Sie einfach schließen die erforderlichen Werte [Server, Dokumentenbibliothek , Benutzer, Domänen, Passwort, etc.] in Ihrem Code):

<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> 

Code:

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 

Answer 2

Überprüfen Sie, ob Sie die internen Namen der Felder verwenden.

To get the internal name of the field, open the "New" form and click "View Source" from context menu (right click any where in the "New" form page to open the context menu). You will see the fields along with their internal names near the end of the source file.

Blick auf den Code:

string strBatch = 

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

...

elBatch.SetAttributeNode("UserName", "Preeti"); 

sind diese tatsächlich zwei getrennte Objekte in Sharepoint?

Versuchen Sie, U2UCamlCreator Tool zu verwenden, um Ihre Sharepoint-Abfragen zu testen.
Dieses Tool hilft Ihnen bei der Erstellung von Batches, um Sharepoint-Felder und viele andere Funktionen zu aktualisieren.
