设计编辑工具栏，如下图所示：

代码如下：

1、form1的load事件里添加：

currentTasks.Items.Add("创建要素");
currentTasks.Items.Add("编辑要素");

2、定义变量

//编辑工具栏变量
        private IEngineEditor m_engineEditor = new EngineEditorClass();
        private IEngineEditLayers m_EngineEditLayers;
        private IEngineEditTask pEngineEditCurentTask;
        private IWorkspace editWorkspace;
        private ArrayList workSpaceArrayList;

3、各个按钮的代码，调用的方法如下：

private void BeginEditToolStripMenuItem_Click(object sender, EventArgs e)
        {
            int featLayerCount = 0;
            ILayer pLayer;
            workSpaceArrayList = new ArrayList();
            for (int i = 0; i <= axMapControl1.Map.LayerCount - 1; i++)
            {
                pLayer = axMapControl1.Map.get_Layer(i);
                if (pLayer is IFeatureLayer)
                {
                    IFeatureLayer pFeatureLayer = pLayer as IFeatureLayer;
                    pFeatureLayer.Selectable = false;
                    IDataset dataset = pFeatureLayer.FeatureClass as IDataset;
                    IWorkspace pWorkspace = dataset.Workspace;
                    if (!workSpaceArrayList.Contains(pWorkspace))
                    {
                        workSpaceArrayList.Add(pWorkspace);
                    }
                    featLayerCount++;
                }

            }
            if (featLayerCount == 0)
            {
                MessageBox.Show("请添加矢量图层后再启动编辑！", "信息提示");
                return;
            }
            IMap map;
            map = axMapControl1.Map;
            //此处可用窗体的进行选择一个工作控件，本例子默认找到的第一个工作空间
            editWorkspace = workSpaceArrayList[0] as IWorkspace;
            m_engineEditor.StartEditing(editWorkspace, map);
            m_EngineEditLayers = m_engineEditor as IEngineEditLayers;
            LoadLayers();
            currentTasks.Text = "创建要素";
            EditingStatesControls(true);
            
        }
        //改函数用于将当前地图中处于编辑工作空间内的所有要素图层添加到currentEditLayer控件中
        private void LoadLayers()
        {
            currentEditLayers.Items.Clear();
            for (int i = 0; i < axMapControl1.LayerCount; i++)
            {
                ILayer pLayer = axMapControl1.get_Layer(i);
                if (pLayer is IFeatureLayer)
                {
                    IFeatureLayer pFeatureLayer = pLayer as IFeatureLayer;
                    IDataset dataset = pFeatureLayer.FeatureClass as IDataset;
                    if (dataset.Workspace == editWorkspace)
                    {
                        currentEditLayers.Items.Add(pLayer.Name);
                    }
                }
            }
            if (currentEditLayers.Items.Count > 0)
            {
                currentEditLayers.SelectedIndex = 0;
            }
        }

       private void SaveEditToolStripMenuItem_Click(object sender, EventArgs e)

问题：

（1）private IEngineEditor m_engineEditor = new EngineEditorClass();这句话如果报错，需要在program.cs的main第一行里添加

ESRI.ArcGIS.RuntimeManager.Bind(ESRI.ArcGIS.ProductCode.EngineOrDesktop);

（2）添加system.collections的命名空间。
