C# +AE加载shp、栅格、地图文档数据

步骤：

1） 创建工作空间工厂

2） 打开shapefile工作空间

3） 打开要素类

4） 创建要素图层

5） 关联图层和要素类

6） 添加到地图空间

具体代码（后面数字为对应的步骤）：

              IWorkspaceFactory pWorkspaceFactory=new ShapefileWorkspaceFactory (); // 1

            openFileDialog1.Filter="shaperfile(*.shp)|*.shp";

            openFileDialog1.InitialDirectory=@"E:\test\文档和数据\Data";

            openFileDialog1.Multiselect=false;

            DialogResult pDialogResult=openFileDialog1.ShowDialog ();

            if(pDialogResult !=DialogResult.OK)

                return;

            string pPath=openFileDialog1 .FileName;

            string pFolder=Path.GetDirectoryName (pPath);

            string pFileName=Path.GetFileName(pPath);

            IWorkspace pWorkspace=pWorkspaceFactory .OpenFromFile(pFolder ,0); // 2

            IFeatureWorkspace pFeatureWorkspace =pWorkspace as IFeatureWorkspace ;

            IFeatureClass pFC=pFeatureWorkspace .OpenFeatureClass (pFileName ); //3

            IFeatureLayer pFLayer=new FeatureLayerClass (); // 4

            pFLayer.FeatureClass =pFC;

            pFLayer.Name =pFC.AliasName ; // 5

            ILayer pLayer=pFLayer as ILayer ;

            IMap pMap=axMapControl1.Map ;

            pMap.AddLayer(pLayer); // 6

            axMapControl1.ActiveView .Refresh ();
