ArcEngine开发之自定义工具栏–打开文件（C#）

1、打开地图文档

创建GIS类，选择Base Command模版，类的名称为OpenNewMapDocument，选择第2类：ArcMap MapControl or PageLayoutControl command

以下为该文档的代码：

using System.Drawing;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using ESRI.ArcGIS.ADF.BaseClasses;
using ESRI.ArcGIS.ADF.CATIDs;
using ESRI.ArcGIS.Controls;
using ESRI.ArcGIS.Carto;

        }

        #endregion
        #endregion

        {
            if (hook == null)
                return;

            if (m_hookHelper == null)

        public override void OnClick()
        {
            //launch a new OpenFile dialog
            OpenFileDialog dlg = new OpenFileDialog();
            dlg.Filter = "Map Documents (*.mxd)|*.mxd";
            dlg.Multiselect = false;
            dlg.Title = "Open Map Document";
            if (dlg.ShowDialog() == DialogResult.OK)
            {
                string docName = dlg.FileName;

                IMapDocument mapDoc = new MapDocumentClass();
                if (mapDoc.get_IsPresent(docName) && !mapDoc.get_IsPasswordProtected(docName))

                    mapDoc.Open(docName, string.Empty);

                    // set the first map as the active view
                    IMap map = mapDoc.get_Map(0);

        public string DocumentFileName
        {
            get { return m_sDocumentPath; }
        }
    }
}

调用此命令：

 OpenNewMapDocument openMapDoc =new OpenNewMapDocument(m_controlsSynchronizer);
            openMapDoc.OnCreate(m_controlsSynchronizer.MapControl.Object);
            openMapDoc.OnClick();

2、打开shapefile文件

//添加Shapefile文件函数
        public void AddShapefile()
        {
            ESRI.ArcGIS.Carto.IActiveView activeView = axMapControl1.ActiveView;
            ESRI.ArcGIS.Carto.IActiveView activeView1 = axMapControl2.ActiveView;

            if (activeView == null)
            {
                return;
            }
            if (activeView1 == null)
            {
                return;
            }

            System.Windows.Forms.OpenFileDialog openFileDialog = new System.Windows.Forms.OpenFileDialog();
            openFileDialog.Filter = "Shapefiles (*.shp)|*.shp";

            if (openFileDialog.ShowDialog() == DialogResult.OK)
            {
                string shapefileLocation = openFileDialog.FileName;
                string pathFile = shapefileLocation;
                if (shapefileLocation != "")
                {

                    IWorkspaceFactory workspaceFactory = new ShapefileWorkspaceFactoryClass();
                    IFeatureWorkspace featureWorkspace = (IFeatureWorkspace)workspaceFactory.OpenFromFile(System.IO.Path.GetDirectoryName(shapefileLocation), 0);
                    IFeatureClass featureClass = featureWorkspace.OpenFeatureClass(System.IO.Path.GetFileNameWithoutExtension(shapefileLocation));
                    IFeatureLayer featureLayer = new FeatureLayerClass();
                    featureLayer.FeatureClass = featureClass;
                    featureLayer.Name = featureClass.AliasName;
                    featureLayer.Visible = true;

                    
                    //添加到主窗口中的代码
                    activeView.FocusMap.AddLayer(featureLayer);
                    activeView.Extent = activeView.FullExtent;
                    activeView.PartialRefresh(esriViewDrawPhase.esriViewGeography, null, null);

                    //添加到鹰眼视图窗口中的代码
                    activeView1.FocusMap.AddLayer(featureLayer);
                    activeView1.Extent = activeView1.FullExtent;
                    activeView1.PartialRefresh(esriViewDrawPhase.esriViewGeography, null, null);
                }
                else
                {
                    MessageBox.Show("操作出错啦!");
                }
            }
        }
