IEngineEditor适用于直接在图层上的编辑，例如使用“要素编辑”工具菜单上的“开始编辑”等工具进行编辑，相应的事件使用IWorkspaceEdit监听，例如以下的代码：

private IEngineEditor m_EngineEditor = new EngineEditorClass();  
private IEngineEditEvents_Event m_EngineEditEvents ;  
private void MainForm_Load(object sender,EventArgs e)  
{  
     //get the MapControl  
     m_mapControl = (IMapControl3)axMapControl1.Object;  
     //disable the Save menu (since there is no document yet)  
     menuSaveDoc.Enabled = false;  
     m_EngineEditEvents = (IEngineEditEvents_Event)m_EngineEditor;  
     m_EngineEditEvents.OnStartEditing += new IEngineEditEvents_OnStartEditingEventHandler(m_EngineEditEvents_OnStartEditing);  
}  
void m_EngineEditEvents_OnStartEditing()  
{  
     MessageBox.Show("Start Editing");       
}

IWorkspaceEdit适用于直接对workspace进行的编辑，相应的事件使用IWorkspaceEditEvents_Event监听，例如以下的代码：

private IWorkspaceEdit wsEdit;  
private IWorkspaceEditEvents_Event wsEditEvents;  
private void MainForm_Load(object sender,EventArgs e)  
{  
      //get the MapControl  
      m_mapControl = (IMapControl3)axMapControl1.Object;  
      //disable the Save menu (since there is no document yet)  
       menuSaveDoc.Enabled = false;  
      wsEdit = MyTool.GetWorkspaceEdit(map1.Map);  
      wsEditEvents = (IWorkspaceEditEvents_Event)wsEdit;  
      wsEditEvents.OnStopEditing += new IWorkspaceEditEvents_OnStopEditingEventHandler(wsEditEvents_OnStopEditing);  
}  
void wsEditEvents_OnStopEditing(bool saveEdits)  
{  
      MessageBox.Show("StopEditing");  
}
