添加shapefile文件

1.新建添加shapefile文件菜单

2.添加代码如下

 private void 添加shapefile文件ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            try
            {
                OpenFileDialog pOpenFileDialog = new OpenFileDialog();
                pOpenFileDialog.CheckFileExists = true;
                pOpenFileDialog.Title = "打开Shape文件";
                pOpenFileDialog.Filter = "Shape文件（*.shp）|*.shp";
                pOpenFileDialog.ShowDialog();

                获取文件路径
                //FileInfo pFileInfo = new FileInfo(pOpenFileDialog.FileName);
                //string pPath = pOpenFileDialog.FileName.Substring(0, pOpenFileDialog.FileName.Length - pFileInfo.Name.Length);
                //mainMapControl.AddShapeFile(pPath, pFileInfo.Name);

                IWorkspaceFactory pWorkspaceFactory;
                IFeatureWorkspace pFeatureWorkspace;
                IFeatureLayer pFeatureLayer;

                string pFullPath = pOpenFileDialog.FileName;
                if (pFullPath == "") return;

                int pIndex = pFullPath.LastIndexOf("\\");
                string pFilePath = pFullPath.Substring(0, pIndex); //文件路径
                string pFileName = pFullPath.Substring(pIndex + 1); //文件名

                //实例化ShapefileWorkspaceFactory工作空间，打开Shape文件
                pWorkspaceFactory = new ShapefileWorkspaceFactory();
                pFeatureWorkspace = (IFeatureWorkspace)pWorkspaceFactory.OpenFromFile(pFilePath, 0);
                //创建并实例化要素集
                IFeatureClass pFeatureClass = pFeatureWorkspace.OpenFeatureClass(pFileName);
                pFeatureLayer = new FeatureLayer();
                pFeatureLayer.FeatureClass = pFeatureClass;
                pFeatureLayer.Name = pFeatureLayer.FeatureClass.AliasName;



                axMapControl1.Map.AddLayer(pFeatureLayer);
                axMapControl1.ActiveView.Refresh();
                //同步鹰眼
                SynchronizeEagleEye();
            }
            catch (Exception ex)
            {
                MessageBox.Show("图层加载失败！" + ex.Message);
            }
        }

 

3.引用的dll文件

using ESRI.ArcGIS.Carto;

using ESRI.ArcGIS.Geodatabase;
