我使用 VSTO 和 C# 开发了一个 Outlook 插件。

第 1 步：我为约会探索创建了一个功能区，当单击功能区按钮时，读取.rtf文件并将.rtf文件插入到约会正文中。

 try
 {
 Outlook.Inspector insp = Globals.ThisAddIn.Application.ActiveInspector();
 Outlook.AppointmentItem meetingItem = insp.CurrentItem() as Outlook.AppointmentItem;
  if(meetingItem == null){
      MessageBox.Show("the meeting is null,create a meeting Item");
      meetingItem = (Outlook.AppointmentItem)insp.Application.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olAppointmentItem);                   
    }
   if(meetingItem != null) {
    meetingItem.MeetingStatus = Outlook.OlMeetingStatus.olMeeting;
    object missing = System.Reflection.Missing.Value;
    Word.Application wordAppl;
    Word.Document wordDoc;
    Word.Selection wordSel = null;
    wordDoc = (Word.Document)insp.WordEditor;
    wordAppl = wordDoc.Parent as Word.Application;
    wordDoc.Activate();
   String path = "D://WordSendTest//template//en_US.rtf";
     String fileName = path.ToString();
     wordSel = (Word.Selection)wordAppl.Selection;
     wordSel.Range.Delete(ref missing, ref missing);
    object falseRef = false;
    wordSel.Range.InsertFile(fileName, ref missing, ref falseRef, ref falseRef, ref falseRef);
    }
   }
    catch (Exception ex)
     {
       MessageBox.Show("Robbin click error!"+ ex.ToString());
     }

第 2 步：当用户单击“发送按钮”时，捕获 ItemSend 事件。

 private void ThisAddIn_Startup(object sender, System.EventArgs e)
        {
            this.Application.ItemSend += new Outlook.ApplicationEvents_11_ItemSendEventHandler(Application_ItemSend);         
        }

第 3 步：在电子邮件正文的末尾插入一些“字符串文本”。 

  void Application_ItemSend(object Item, ref bool Cancel)
        {
            Outlook.Inspector insp = Globals.ThisAddIn.Application.ActiveInspector();
            Outlook.AppointmentItem meeting = insp.CurrentItem as Outlook.AppointmentItem;
            Word.Document wordDoc = insp.WordEditor as Word.Document;
            Word.Application wordApp = wordDoc.Parent as Word.Application;
            Word.Selection wordSel =(Word.Selection) wordApp.Selection;
            object missing = System.Reflection.Missing.Value;
            object units = Microsoft.Office.Interop.Word.WdUnits.wdStory;
            object findEnd = (object)"~-----~~-----~-----~-----~-----~-----~\r";
            object wholeWord = true;
            wordSel.HomeKey(ref units, ref missing);
            if(wordSel.Find.Execute(ref findEnd,ref missing,ref wholeWord,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing))
            {
            wordSel.MoveUp(ref missing,ref missing,ref missing);
            wordSel.TypeText("--=Head for Insert info =--\n");
            wordSel.TypeText("when user click the <send button>,the Tex info will be insert and show here \n");
            wordSel.TypeText("--=End for Insert info=--\n");
            }
            else {
               MessageBox.Show("not fonud the END tag");
            }
        }

问题：在调试模型中，单击发送按钮时，添加文本成功插入正文。但是，实际发出的邮件并没有改变，只是在点击“发送按钮”之前相同。当我在日历中打开约会时，正文没问题，文本已成功插入邮件正文的末尾。

那么，谁知道为什么？为什么邮件没有与更新正文一起发送，而是更新邮件正文保存在日历中。

您修改文本的代码是什么？什么时候执行？请记住，约会永远不会发送。当您单击发送时，Outlook 会创建一个 MeetingRequest 对象并改为发送它。只有在处理 Application.ItemSend 事件时才能修改该对象。
