1、AE加载Shapefile、栅格、CAD、PersonGDB、SDE数据ArcEngine加载图层的五个步骤1.创建一个类工厂2.使用类工厂创建一个要使用的工作区3.使用工作区打开并得到图层的dataset4.把dataset装入到新建的图层实例5.把图层加载到MapControl控件1.加载Shapefile数据            IWorkspaceFactory pWorkspaceFactory;             IFeatureWorkspace pFeatureWorkspace;             IFeatureLayer pFeatureLaye

2、r;              //获取当前路径和文件名             OpenFileDialog dlg = new OpenFileDialog();             dlg.Filter = "Shape(*.shp)

3、*.shp

4、All Files(*.*)

5、*.*";             dlg.Title = "Open Shapefile data";             dlg.ShowDialog();            string strFullPath = dlg.FileName;            if (strFul

6、lPath == "") return;            int Index = strFullPath.LastIndexOf("//");            string filePath = strFullPath.Substring(0, Index);            string fileName = strFullPath.Substring(Index + 1);            //打开工作空间并添加shp文件            pWorkspaceFactory = new ShapefileWorkspaceFactoryClass(

7、);           pFeatureWorkspace = (IFeatureWorkspace)pWorkspaceFactory.OpenFromFile(filePath, 0);            pFeatureLayer = new FeatureLayerClass();                    pFeatureLayer.FeatureClass = pFeatureWorkspace.OpenFeatureClass(fileName);            pFeatureLayer.Name = pFeatureLayer.Featu

8、reClass.AliasName;            axMapControl1.Map.AddLayer(pFeatureLayer);            axMapControl1.ActiveView.Refresh();2.加载栅格数据            IWorkspaceFactory pWorkspaceFactory;            IRasterWorkspace pRasterWorkspace;             OpenFileDialog dlg = new OpenFileDialog();             dlg.F

9、ilter = "Layer File(*.lyr)

10、*.jpg;*.bmp;*.tiff";             dlg.Title = "Open Raster Data File";             dlg.ShowDialog();             //获取当前路径和文件名             string strFullPath = dlg.FileName;            if (strFullPath == "") return;            int Index = strFullPath.LastIndexOf("//");

11、            string fileName = strFullPath.Substring(Index + 1);            string filePath = strFullPath.Substring(0, Index);            pWorkspaceFactory = new RasterWorkspaceFactoryClass();            pRasterWorkspace = (IRasterWorksp
