How to Retain/Preserve "Modified By" while checking in a file
SPSite
mySite = new SPSite("<SiteURL>");
SPWeb myWeb = mySite.OpenWeb();
SPFolder myList = myWeb.Folders["<DocLibName>"];
SPFile myFile = myList.Files[0];
SPUser
myUser = myWeb.Users["<User_Name>"];
CheckInFileByUser(myFile,
"Checkin Comments", SPCheckinType.MajorCheckIn, myUser);
public
static void CheckInFileByUser(SPFile file, string checkinComment,SPCheckinType checkinType,SPUser modifiedByUser)
{
MethodInfo mi = typeof(SPFile).GetMethod("CheckIn",BindingFlags.Instance | BindingFlags.NonPublic, null, new Type[] { typeof(string), typeof(SPCheckinType), typeof(bool), typeof(SPUser) }, null);
try
{
mi.Invoke( file,
new object[] { checkinComment, checkinType, false, modifiedByUser });
}
catch (Exception ex)
{
MessageBox.Show(ex.StackTrace);
}
}
Before calling this code you will need to Check out the file, otherwise you will get an error.
