C＃VSTO Outlook加载项 - 调试文本选择事件？

Question

我正在构建一个Outlook加载项，我想对电子邮件正文中的文本选择更改做出反应。

为此，我将一个WindowSelectionChange event附加到邮件项目检查器中的Word对象。

if (inspector.IsWordMail()) 
    { 
     wordDoc = inspector.WordEditor as Word.Document; 
     wordDoc.Application.WindowSelectionChange += new Microsoft.Office.Interop.Word.ApplicationEvents4_WindowSelectionChangeEventHandler(text_selected); 
    } 

这工作正常，但事件停止发射选择，看似随意。我一整天都在这里，并且无法解决问题。

环顾四周后，我发现它可能是wordDoc对象被垃圾收集，所以我确保将它设置为类变量。

无论如何，也许没有整个项目，它很难找出问题的确切原因......我的问题是更多的，我将如何去调试这个？如果事件没有被解雇，我没有任何断点。如果我的事件侦听器不是wordDoc应用程序中的属性，我该如何监视事件侦听器的状态？

下面是来自相关课程的大部分代码，只是删除了一些代码。我很抱歉的混乱 - 我学习，我这个去...

public class InspectorWrapper 
     { 
      private Outlook.Inspector inspector; 
      private CustomTaskPane taskPane; 
      private Dictionary<string, List<ScanResult>> mailItemEntities; 

      private bool activated, loaded; 
      private Word.Document wordDoc; 

      public InspectorWrapper(Outlook.Inspector Inspector) 
      { 
       inspector = Inspector; 

       loaded = false; 
       activated = false; 

       ((Outlook.InspectorEvents_Event)inspector).Close += 
        new Outlook.InspectorEvents_CloseEventHandler(InspectorWrapper_Close); 

       taskPane = Globals.ThisAddIn.CustomTaskPanes.Add(
        new TaskPaneControl(), "Addin", inspector); 
       taskPane.VisibleChanged += new EventHandler(TaskPane_VisibleChanged); 

       mailItemEntities = new Dictionary<string, List<ScanResult>>(); 

       ((Outlook.InspectorEvents_10_Event)inspector).Activate += new Outlook.InspectorEvents_10_ActivateEventHandler(ThisAddIn_Activate); 
      } 

      void ThisAddIn_Activate() 
      { 
       activated = true; 
      } 

      void text_selected(Word.Selection selected_text) 
      { 
       if (activated && loaded) 
       { 
        ((TaskPaneControl)this.CustomTaskPane.Control).text_selected(selected_text.Text, selected_text.End - selected_text.Start); 

       } 
      } 

      void TaskPane_VisibleChanged(object sender, EventArgs e) 
      { 
       Globals.Ribbons[inspector].Ribbon1.toggleButton1.Checked = taskPane.Visible; 
       if (!loaded) { 
        process_email(this.inspector.CurrentItem as Outlook.MailItem); 
        if (inspector.IsWordMail()) 
        { 
         wordDoc = inspector.WordEditor as Word.Document; 
         wordDoc.Application.WindowSelectionChange += new Microsoft.Office.Interop.Word.ApplicationEvents4_WindowSelectionChangeEventHandler(text_selected); 
        } 
        loaded = true; 
       } 
      } 

      void InspectorWrapper_Close() 
      { 
       if (taskPane != null) 
       { 
        Globals.ThisAddIn.CustomTaskPanes.Remove(taskPane); 
       } 

       activated = false; 
       loaded = false; 
       taskPane = null; 
       Globals.ThisAddIn.InspectorWrappers.Remove(inspector); 
       ((Outlook.InspectorEvents_Event)inspector).Close -= 
        new Outlook.InspectorEvents_CloseEventHandler(InspectorWrapper_Close); 
       ((Outlook.InspectorEvents_10_Event)inspector).Activate -= 
        new Outlook.InspectorEvents_10_ActivateEventHandler(ThisAddIn_Activate); 
       inspector = null; 
      } 
     } 

这是我主要的加载项类，如果它的事项：

public partial class ThisAddIn 
    { 
     Outlook.Inspectors inspectors; 
     Outlook.MailItem mailItem; 
     private string last_id = ""; 
     private Dictionary<Outlook.Inspector, InspectorWrapper> inspectorWrappersValue = 
      new Dictionary<Outlook.Inspector, InspectorWrapper>(); 
     private Outlook.Inspector ins; 

     private void ThisAddIn_Startup(object sender, System.EventArgs e) 
     { 
      inspectors = this.Application.Inspectors; 

      inspectors.NewInspector += new Outlook.InspectorsEvents_NewInspectorEventHandler(Inspectors_NewInspector); 

     } 

     void Inspectors_NewInspector(Microsoft.Office.Interop.Outlook.Inspector Inspector) 
     { 

      ins = Inspector; 
      Outlook.MailItem mailItem = ins.CurrentItem as Outlook.MailItem; 
      if (mailItem != null) 
      { 
       inspectorWrappersValue.Add(ins, new InspectorWrapper(ins)); 
      } 
     } 

     private void ThisAddIn_Shutdown(object sender, System.EventArgs e) 
     { 
      // Note: Outlook no longer raises this event. If you have code that 
      // must run when Outlook shuts down, see http://go.microsoft.com/fwlink/?LinkId=506785 
      inspectors.NewInspector -= 
       new Outlook.InspectorsEvents_NewInspectorEventHandler(
       Inspectors_NewInspector); 
      inspectors = null; 
      inspectorWrappersValue = null; 
     } 

     public Dictionary<Outlook.Inspector, InspectorWrapper> InspectorWrappers 
     { 
      get 
      { 
       return inspectorWrappersValue; 
      } 
     } 

     #region VSTO generated code 

     /// <summary> 
     /// Required method for Designer support - do not modify 
     /// the contents of this method with the code editor. 
     /// </summary> 
     private void InternalStartup() 
     { 
      this.Startup += new System.EventHandler(ThisAddIn_Startup); 
      this.Shutdown += new System.EventHandler(ThisAddIn_Shutdown); 
     } 

     #endregion 
    }

这不是wordDoc变量这引发了这个事件并且正在被垃圾收集。它是从wordDoc.Application返回的Application对象：
