            using (Database dbInsert = new Database(false, true))
            {
              dbInsert.ReadDwgFile(sDwg, System.IO.FileShare.ReadWrite, true, null);
              DatabaseExtension.Audit(dbInsert, true, true);
              dbInsert.RetainOriginalThumbnailBitmap = true;
              dbInsert.SaveAs(sDwg, true, DwgVersion.AC1027, dbInsert.SecurityParameters);
            }

You just need to insert the following line into your code before it calls SaveAs():

db.RetainOriginalThumbnailBitmap = true;

Where 'db'  is the variable in your code, which the Database is assigned to.
