Exception "Invalid part tag"

[mikaso]

Hi all,
I wanted to write some function which starts with opening of part then it do somethink and finish with SaveAs. But during SaveAs method I recieve for some parts exception with meassage "Invalid part tag", errorcode is 641018. I don't have any idea what does it mean

Code:
foreach (string path in partlist)
{
try
{
session.ListingWindow.WriteLine(System.DateTime.UtcNow.ToShortTimeString() + @": " + partlist.IndexOf(path) + @" : " + System.IO.Path.GetFileName(path));
dp = session.Parts.Open(path, out pls);
dp.SaveAs(conf.TargetPath + @"\" + System.IO.Path.GetFileName(path));
}
catch (Exception e)
{
session.ListingWindow.WriteLine(e.Message);

}
finally
{
if (dp != null)
{
dp.Close(BasePart.CloseWholeTree.True, BasePart.CloseModified.CloseModified, null);
}
}
}

Make sure when you open the part, the part has opened successfully. Also, you can check before saveas that the tag is not null.

Dear Suresh, I checked it. If I try to open part by hand and make SaveAs it works fine. I checked with debugger if I have Tag for part and for session. I think that problem could be somewhere else. I want to use this function to break family members. But I didn't find any different way how to do it, only this SaveAs operation. What is strange that it appears only with few parts.

Well, I solved it myself:

foreach (string path in partlist)
            {
                try
                {
                    session.ListingWindow.WriteLine(System.DateTime.UtcNow.ToShortTimeString() + @": " + partlist.IndexOf(path) + @" : " + System.IO.Path.GetFileName(path));
                    dp = session.Parts.Open(path, out pls);                
                    dp.SaveAs(conf.TargetPath + @"\" + System.IO.Path.GetFileName(path));
                }
                catch (Exception e)
                {
                    session.ListingWindow.WriteLine(e.Message);
                    [b]dp.Close(BasePart.CloseWholeTree.True, BasePart.CloseModified.CloseModified, null);
                    dp = session.Parts.OpenDisplay(path, out pls);
                    dp.SaveAs(conf.TargetPath + @"\" + System.IO.Path.GetFileName(path));[/b] 
                }
                finally
                {
                    if (dp != null)
                    {
                        dp.Close(BasePart.CloseWholeTree.True, BasePart.CloseModified.CloseModified, null);
                    }
                }

In the case exception appears I close part and open it again and display. Then I call SaveAs and it works.
