如何在C#中从Outlook处获取MailItem的最新回复？

using Outlook = Microsoft.Office.Interop.Outlook;

public Outlook.MailItem GetLatestReply(Outlook.MailItem mailItem)
{
    Outlook.MailItem latestReply = null;
    
    // 获取所有与该邮件相关的回复
    Outlook.Items replies = mailItem.Replies;
    
    // 遍历回复集合，找到最新的回复
    foreach (Outlook.MailItem reply in replies)
    {
        if (latestReply == null || reply.ReceivedTime > latestReply.ReceivedTime)
        {
            latestReply = reply;
        }
    }
    
    return latestReply;
}
