AE根据记录信息获得地图元素信息并定位地图位置

                //获得属性值

                            axMapControl.ActiveView.PartialRefresh(esriViewDrawPhase.esriViewGeoSelection, null, null);
                            axMapControl.ActiveView.PartialRefresh(esriViewDrawPhase.esriViewGeography, null, null);
                            break;

                    catch { }
                }

这边要注意的是你需要定位的图层必须要有你需要查询的属性,在遍历整个地图的话则比较难统一字段,所以在获得元素的地方需要Catch掉容错.

图层也可以直接定义,假如你知道的话.
