get/detect corrupt/recoverable drawing file

[autoDeveloper]

Hello,

I tried to use    using (Database db = new Database(false, false))

{        

        try        

         {              

                   db.ReadDwgFile(docname, FileOpenMode.OpenForReadAndWriteNoShare, false, null);                                   

                   db.CloseInput(true);      

         }      

        catch (System.Exception ex)      

         {      

         }

}  

But above code also crashing and show fatal error while running using accoreconsole.exe. Fatal error screenshot attached. Please help how console program can catch this issue.    

Thanks in advance
