Question

如何在Outlook对话中获取最后一个回复？例如，以下代码：

Outlook.MailItem item = Items.GetLast();
MessageBox.Show(item.Body);

将显示整个电子邮件，而不仅仅是最后的回复。

以下示例显示如何在对话中获取和显示邮件项目。

void DemoConversation()
{
   object selectedItem = Application.ActiveExplorer().Selection[1];
   // For this example, you will work only with 
   //MailItem. Other item types such as
   //MeetingItem and PostItem can participate 
   //in Conversation.
   if (selectedItem is Outlook.MailItem)
   {
      // Cast selectedItem to MailItem.
      Outlook.MailItem mailItem = selectedItem as Outlook.MailItem; 
      // Determine store of mailItem.
      Outlook.Folder folder = mailItem.Parent as Outlook.Folder;
      Outlook.Store store = folder.Store;
      if (store.IsConversationEnabled == true)
      {
         // Obtain a Conversation object.
         Outlook.Conversation conv = mailItem.GetConversation();
         // Check for null Conversation.
         if (conv != null)
         {
            // Obtain Table that contains rows 
            // for each item in Conversation.
            Outlook.Table table = conv.GetTable();
            Debug.WriteLine("Conversation Items Count: " +                   table.GetRowCount().ToString());
            Debug.WriteLine("Conversation Items from Table:");
            while (!table.EndOfTable)
            {
                Outlook.Row nextRow = table.GetNextRow();
                Debug.WriteLine(nextRow["Subject"]
                    + " Modified: "
                    + nextRow["LastModificationTime"]);
            }
            Debug.WriteLine("Conversation Items from Root:");
            // Obtain root items and enumerate Conversation.
            Outlook.SimpleItems simpleItems = conv.GetRootItems();
            foreach (object item in simpleItems)
            {
                // In this example, enumerate only MailItem type.
                // Other types such as PostItem or MeetingItem
                // can appear in Conversation.
                if (item is Outlook.MailItem)
                {
                    Outlook.MailItem mail = item as Outlook.MailItem;
                    Outlook.Folder inFolder = mail.Parent as Outlook.Folder;
                    string msg = mail.Subject 
                        + " in folder " + inFolder.Name;
                    Debug.WriteLine(msg);
                }
                // Call EnumerateConversation 
                // to access child nodes of root items.
                EnumerateConversation(item, conv);
             }
          }
       }
    }
 }

 void EnumerateConversation(object item, Outlook.Conversation conversation)
 {
    Outlook.SimpleItems items = conversation.GetChildren(item);
    if (items.Count > 0)
    {
      foreach (object myItem in items)
      {
        // In this example, enumerate only MailItem type.
        // Other types such as PostItem or MeetingItem
        // can appear in Conversation.
        if (myItem is Outlook.MailItem)
        {
           Outlook.MailItem mailItem = myItem as Outlook.MailItem;
            Outlook.Folder inFolder = mailItem.Parent as Outlook.Folder;
            string msg = mailItem.Subject
                + " in folder " + inFolder.Name;
            Debug.WriteLine(msg);
        }
        // Continue recursion.
        EnumerateConversation(myItem, conversation);
      }
   }
}

在示例代码示例中，我们获取一个选定的MailItem对象，然后使用MailItem对象的Store属性确定Folder对象的存储。然后DemoConversation检查IsConversationEnabled属性是否为真;如果是，则代码示例使用Conversation方法获取GetConversation对象。如果Conversation对象不是空引用，则该示例使用Table方法获取包含对话中每个项的关联GetTable对象。然后，该示例枚举Table中的每个项目，并在每个项目上调用EnumerateConversation以访问每个项目的子节点。 EnumerateConversation使用Conversation对象并使用GetChildren(Object)方法获取子节点。递归调用EnumerateConversation，直到没有更多的子节点。然后将每个对话项目显示给用户。
