• 回答：

  
      var database = mxOcx.GetDatabase();
      var ret = database.GetProp("getMinDrawOrder");
      var lMin = ret.AtLong(0);
  
      var ret2 = database.GetProp("getMaxDrawOrder");
      var lMax = ret2.AtLong(0);
  
      var sTemp = mxOcx.DrawImage(0, 0, 0, 0, "D:\\mxcad.jpg");
      var ent = database.ObjectIdToObject(sTemp);
  
      var res = mxOcx.NewResbuf();
      res.AddLong(lMin + 2);
  
      ent.SetProp("drawOrder", res);
      mxOcx.ZoomAll();
