sharepoint-2010 - 从 Client Objectmodel 更新 ListItem 而不更改版本

Question

是否可以在不更新版本的情况下使用 Sharepoint Client ObjectModel 更新 Created/Modified 字段？

var file = _ClientContext.Web.GetFileByServerRelativeUrl(serverRelativeUrl);
_ClientContext.Load(file);
_ClientContext.ExecuteQuery();
ListItem listItem = file.ListItemAllFields;
listItem["Created"] = info.SourceFile.CreationTime;
listItem["Modified"] = info.SourceFile.LastWriteTime;
MapMembers(listItem, info.MetaData);
listItem.Update();

listItem.SystemUpdate / Update(false) 在客户端 ObjectModel 中不可用。

谢谢

Microsoft.SharePoint.Client.File lp_newFile = lp_web.GetFileByServerRelativeUrl(lp_uri.LocalPath);
lp_context.Load(lp_newFile);
lp_context.ExecuteQuery();

//check out to make sure not to create multiple versions
lp_newFile.CheckOut();

ListItem lp_item = lp_newFile.ListItemAllFields;
listItem["Created"] = info.SourceFile.CreationTime;
listItem["Modified"] = info.SourceFile.LastWriteTime;
listItem.Update();

// use OverwriteCheckIn type to make sure not to create multiple versions 
lp_newFile.CheckIn(string.Empty, CheckinType.OverwriteCheckIn);
