使用DevExpress展示地图加载SHP

private void LoadShp(string path){    //创建SHP数据源    ShapefileDataAdapter dataAdapter = new ShapefileDataAdapter    {        FileUri = new Uri(path),        SourceCoordinateSystem = new CartesianSourceCoordinateSystem(), //坐标系        DefaultEncoding = Encoding.UTF8, //编码    };     //创建矢量图层    VectorItemsLayer vectorItemsLayer = new VectorItemsLayer    {        Data = dataAdapter,        Colorizer = CreateChoroplethColorizer("SCP") //分级符号化    };    vectorItemsLayer.Name = "任务区";     //标注    vectorItemsLayer.ShapeTitlesVisibility = VisibilityMode.Visible;    vectorItemsLayer.ShapeTitlesPattern = "{Name}:{ SCP }%";     //设置地图控件属性    this.mapControl1.CoordinateSystem = new CartesianMapCoordinateSystem();    this.mapControl1.NavigationPanelOptions.Visible = false;     //加载图层    mapControl1.Layers.Add(vectorItemsLayer);     //加载图例    MapLegendBase mapLegendBase = CreateLegend(vectorItemsLayer);    mapLegendBase.Alignment = LegendAlignment.TopLeft;    this.mapControl1.Legends.Add(mapLegendBase);}
