using (Transaction trans = doc.TransactionManager.StartTransaction())
         {
            BlockTable BlkTab = (BlockTable)trans.GetObject(doc.Database.BlockTableId, OpenMode.ForRead) as BlockTable;
            BlockTableRecord btr = (BlockTableRecord)trans.GetObject(BlkTab[BlockTableRecord.ModelSpace], OpenMode.ForRead);
            foreach (ObjectId ID in btr)
            {
                  Entity Ent = trans.GetObject(ID,OpenMode.ForRead,true) as Entity;
                  if (Ent != null)
                  {
                     if (Ent is BlockReference)
                     {
                              Blk.Color=??????????  //这里怎么写，怎么给块颜色
                     }
