C#、AE开发入门之打开CAD文件并显示

加载CAD文件稍显复杂一些，总体还是和前面基本类似

　　　　　private void button3_Click(object sender, EventArgs e)

        {

            axMapControl1.ClearLayers();

            IWorkspaceFactory pWF = new ESRI.ArcGIS.DataSourcesFile.CadWorkspaceFactory();//利用工厂对象去生成一个CAD文件的工作空间

            IWorkspace pW = pWF.OpenFromFile(cadPath,);    //打开对应的文件夹路径

            IFeatureWorkspace pFW = (IFeatureWorkspace)pW;

            IFeatureClass pFW_text = pFW.OpenFeatureClass("裙子.dwg:Polygon");//利用要素类去接收对应的cad文件中的面属性

            IFeatureLayer pFeatureLayer2 = new FeatureLayerClass();//生成一个要素图层对象

            pFeatureLayer2.FeatureClass = pFW_text;//将接收要素类的cad文件赋值给要素图层的要素类属性

            axMapControl1.AddLayer(pFeatureLayer2);//添加对应的polygon图层

            IFeatureClass pFC = pFW.OpenFeatureClass("裙子.dwg:Polyline");//利用要素类去接收对应的cad文件中的线属性

            IFeatureLayer pFeatLyr = new FeatureLayerClass();//生成一个要素图层对象（接收线）

            pFeatLyr.FeatureClass = pFC;//将线属性赋值给对应的要素图层

            ISimpleLineSymbol pLineSymbol = new SimpleLineSymbolClass();//创建一个线特征对象

            IRgbColor pColor = new RgbColorClass();//生成一个颜色控制的接口

            pColor.Red = ;

            pColor.Blue = ;

            pColor.Green = ;

            pLineSymbol.Color = (IColor)pColor;//将线对象的颜色设置为对应的颜色

            pLineSymbol.Style = esriSimpleLineStyle.esriSLSSolid;//设置线的样式

            ISimpleRenderer pRender = new SimpleRendererClass();

            pRender.Symbol = pLineSymbol as ISymbol;

            IGeoFeatureLayer pGeoLyr = pFeatLyr as IGeoFeatureLayer;

            pGeoLyr.Renderer = pRender as IFeatureRenderer;

            axMapControl1.AddLayer(pFeatLyr);

            axMapControl1.ActiveView.Refresh();

        }
