执行以下操作:
XmlDocument xmlDoc = new XmlDocument();
XmlElement updates = xmlDoc.CreateElement("Batch");
updates.SetAttribute("OnError", "Continue");
updates.SetAttribute("ListVersion", "0");
updates.SetAttribute("ViewName", "");
updates.InnerXml = "<Method ID=\"1\" Cmd=\"Update\">" +
"<Field Name=\"ID\">" + listItemId + "</Field>" +
"<Field Name=\"Title\">ModifiedFile</Field>" +
"<Field Name=\"FileRef\">" + theFileInSharepoint + "</Field>"+
"<Field Type=\"ContentTypeId\">" + contentTypeId + "</Field></Method>";
myListSoapClient.UpdateListItems(myListGuid, updates);
如果更新包含<Field Type=\"ContentTypeId\">
节点,则UpdatelistItems将抛出(抛出类型为'Microsoft.SharePoint.SoapServer.SoapServerException'的异常。)。删除它,并应用更新。
是否可以通过sharepoint的web服务修改listItem ContentTypeId?
