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
                string ManagerId = dgvK001.Rows[e.RowIndex].Cells[0].Value.ToString();
                string RoadId = dgvK001.Rows[e.RowIndex].Cells[2].Value.ToString();
                if (RoadId.IndexOf("S") != -1 || RoadId.IndexOf("G") != -1)
                    RoadId = RoadId.Substring(0, 4);
                string StartStake = dgvK001.Rows[e.RowIndex].Cells[5].Value.ToString();
                //遍历整个地图
                for (int i = 0; i < axMapControl.LayerCount; i++)
                {

                    IFeatureClass iFeatureClass = null;
                    //获得图层
                    pLayer = (IFeatureLayer)axMapControl.get_Layer(i);
                    iFeatureClass = pLayer.FeatureClass;
                    //定义AE游标
                    IFeatureCursor pCursor;
                    //构建查询条件
                    IQueryFilter pFilter = new QueryFilterClass();

                    //多字段查询
                    pFilter.WhereClause = " LXBM = '" + RoadId.Trim() + "'" + " AND DWDM = '" + ManagerId.Trim() + "'" + "  AND QDZH=" + StartStake.Trim() + "";
                    try
                    {
                        pCursor = iFeatureClass.Search(pFilter, false);
                        IFeature pFeature;
//获得查询的元素
                        pFeature = pCursor.NextFeature();

                        if (pFeature != null)
                        {
                            //要素的定义,如果是点直接定位
                            if (pFeature.Shape.GeometryType == esriGeometryType.esriGeometryPoint)
                            {
                                this.axMapControl.CenterAt((IPoint)pFeature.Shape);
                            }
                            else
                            {
                                //获得定位的范围
                                IEnvelope pEnv = pFeature.Shape.Envelope;
                                pEnv.Expand(5, 5, true);
                                axMapControl.ActiveView.Extent = pEnv;
                            }
                            axMapControl.ActiveView.Refresh();
                            axMapControl.ActiveView.ScreenDisplay.UpdateWindow();
                            //用于解决先定位后闪烁的问题
                            //自定义闪烁功能
                            switch (pFeature.Shape.GeometryType)
                            {
                                case esriGeometryType.esriGeometryPoint:
                                    FlashFeature.FlashPoint(axMapControl, axMapControl.ActiveView.ScreenDisplay, pFeature.Shape);
                                    break;
                                case esriGeometryType.esriGeometryPolyline:
                                    FlashFeature.FlashLine(axMapControl, axMapControl.ActiveView.ScreenDisplay, pFeature.Shape);
                                    break;
                                case esriGeometryType.esriGeometryPolygon:
                                    FlashFeature.FlashPolygon(axMapControl, axMapControl.ActiveView.ScreenDisplay, pFeature.Shape);
                                    break;
                                default:
                                    break;
                            }

                            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.
