C#+ArcEgine开发（2）添加shp和lyr文件

都是《ArcGIS Egine+C#入门经典》里的例子，可以找来看看

数据都是用的ArcEgine安装好后自带的数据

路径应该是   ArcGIS\DeveloperKit10.2\Samples\data

---------------------------------------------------------------------------------------------------------------------------

在上一个例子的窗体上拖一个menuStrip进去，再拖一个openFileDialog进去

最后的成果是这样的

1、添加shapfile文件

代码如下：

 private void 添加shp文件ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            IWorkspaceFactory pWorkspaceFactory = new ShapefileWorkspaceFactory();
            //文件过滤，选择后缀为.shp
            openFileDialog1.Filter = "ShapeFile文件(*.shp)|*.shp";
            if(openFileDialog1.ShowDialog()==DialogResult.OK)
            {
                string pPathName = openFileDialog1.FileName;
                string pFolder = System.IO.Path.GetDirectoryName(pPathName);
                string pFileName = System.IO.Path.GetFileName(pPathName);
                IWorkspace pWorkspace = pWorkspaceFactory.OpenFromFile(pFolder, 0);
                IFeatureWorkspace pFeatureWorkspace = pWorkspace as IFeatureWorkspace;
                IFeatureClass pFC = pFeatureWorkspace.OpenFeatureClass(pFileName);
                IFeatureLayer pFLayer = new FeatureLayerClass();
                pFLayer.FeatureClass = pFC;
                pFLayer.Name = pFC.AliasName;
                ILayer pLayer = pFLayer as ILayer;
                IMap pMap = axMapControl1.Map;
                pMap.AddLayer(pLayer);
                axMapControl1.ActiveView.Refresh();
            }
           

        }

2、添加lyr文件

 private void 添加lyr文件ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            openFileDialog1.Filter = "lyr文件(*.lyr)|*.lyr";
            //openFileDialog1.InitialDirectory = @"C:\Program Files (x86)\ArcGIS\DeveloperKit10.2\Samples\data\World";
            //openFileDialog1.Multiselect = false;
            //DialogResult pDialogResult = openFileDialog1.ShowDialog();
            //if (pDialogResult != DialogResult.OK)
            //    return;
            if (openFileDialog1.ShowDialog() == DialogResult.OK)
            {
                string pFileName = openFileDialog1.FileName;
                axMapControl1.AddLayerFromFile(pFileName);
                axMapControl1.ActiveView.Refresh();
            }          
             
        }
