打开shapfile,raster文件

打开shapfile文件，代码如下

 1  //打开工作空间需要对应的工作空间工厂
 2            IWorkspaceFactory PWorkSpaceFactory = new ShapefileWorkspaceFactory();
 3
 4            IFeatureWorkspace PFeatureWorkSpace;
 5            IFeatureLayer PFeatureLayer = new FeatureLayerClass();
 6            OpenFileDialog Open = new OpenFileDialog();
 7
 8            Open.Title = "Select File";
 9            Open.Filter = "shapefiel(.shp)|*.shp";
10
11            Open.ShowDialog();
12
13            string strFullPath = Open.FileName;
14            if (strFullPath == "") return;
15
16            //提取文件名和打开路径
17            int index = strFullPath.LastIndexOf("\\");
18            string filepath = strFullPath.Substring(0, index);
19            string filename = strFullPath.Substring(index + 1);
20
21            //设置shapefile工作空间，即打开路径
22            PFeatureWorkSpace = (IFeatureWorkspace)PWorkSpaceFactory.OpenFromFile(filepath, 0);
23
24            //打开一个类要素
25            PFeatureLayer.FeatureClass = PFeatureWorkSpace.OpenFeatureClass(filename);
26            //PFeatureLayer.Name = PFeatureLayer.FeatureClass.AliasName;
27
28            //首先清空已有图层
29            axMapControl1.Map.ClearLayers();
30
31            //添加图层
32            axMapControl1.Map.AddLayer(PFeatureLayer);
33            axMapControl1.Refresh();

打开Raster文件

 1IWorkspaceFactory PWorkSpaceFactory = new RasterWorkspaceFactory();
 2            IRasterWorkspace PRasterWorkSpace;
 3            IRasterDataset PRasterDataset = new RasterDatasetClass();
 4            IRasterLayer PRasterlayer = new RasterLayerClass();
 5            OpenFileDialog Open = new OpenFileDialog();
 6
 7            Open.Title = "Select File";
 8            Open.Filter = "Layer File(*.lyr)|*.jpg;*.bmp;*.tiff";
 9
10            Open.ShowDialog();
11            string strFullPath = Open.FileName;
12            if (strFullPath == "") return;
13
14            //提取栅格数据集名称和打开路径
15            int index = strFullPath.LastIndexOf("\\");
16            string filepath = strFullPath.Substring(0, index);
17            string filename = strFullPath.Substring(index + 1);
18
19            PRasterWorkSpace = (IRasterWorkspace)PWorkSpaceFactory.OpenFromFile(filepath,0);
20            PRasterDataset = (IRasterDataset)PRasterWorkSpace.OpenRasterDataset(filename);
21
22            //初始化一个新的Rasterlayer有三种方式CreateFromDataset，CreateFromFilePath，CreateFromRaster
23
24            //CreateFromDataset方式
25            PRasterlayer.CreateFromDataset(PRasterDataset);
26
27            //CreateFromFilePath方式
28            //PRasterlayer.CreateFromFilePath(strFullPath);
29
30            axMapControl1.Map.ClearLayers();
31            axMapControl1.AddLayer(PRasterlayer);
32            axMapControl1.Refresh();

其他的类型文件，如Coverage，Geodatabase，CAD，等等，原理类似，改天贴上来^_^
