与收件箱和发送的项目相关的c# Outlook

我正在开发一个软件，我可以从outlook中检索收件箱和发送的项目。我想做的是将收件箱中的电子邮件与回复联系起来(如果有人给那封电子邮件发了回复)。该列表应按以下顺序显示

Sender@abc.com进入受试者接收时间sender@abc.com回复主题发送时间

我打算做的是检索一个数据表中的收件箱项目和另一个数据表中的发送项目。它根据发件人电子邮件和主题逐个读取电子邮件，然后在发送的项目中搜索发件人和电子邮件，如果匹配，则将其合并到第三个数据表中。

还有其他更好的方法吗?

代码如下:

 private DataTable GetInboxItems()
    {
        DataTable inboxTable;
        //try
        //{
        filter = "[ReceivedTime] >= '" + dtpStartDate.Value.ToString("dd/MM/yyyy 12:00 AM") + "' and [ReceivedTime] <= '" + dtpEndDate.Value.ToString("dd/MM/yyyy  11:59 PM") + "'";
        Outlook.Application outlookApp = GetApplicationObject();
        Outlook.Folder root = outlookApp.Session.DefaultStore.GetRootFolder() as Outlook.Folder;
        EnumerateFolders(root);
        //string filter = "[ReceivedTime] > '" + dtpStartDate.Value.ToString("dd/MM/yyyy") + "'";
        //inbox
        Outlook.MAPIFolder inboxFolder = outlookApp.Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);
        inboxTable = CreateTable();
        int count = 0;

        if (inboxFolder.Items.Count > 0)
        {
            var restrictedItems = inboxFolder.Items.Restrict(filter);
            restrictedItems.Sort("[ReceivedTime]", true); //descending
            //foreach (var item in inboxFolder.Items)
            foreach (var item in restrictedItems)
            {
                var mail = item as Outlook.MailItem;
                if (mail != null)
                {
                    //try
                    //{
                    DataRow row = inboxTable.NewRow();
                    //row["sn"] = (++count).ToString();
                    row["sn"] = mail.EntryID + " " + mail.ReceivedByEntryID;
                    row["MailType"] = "Inbox";
                    row["SenderName"] = mail.SenderName;
                    row["SenderEmail"] = mail.SenderEmailAddress;
                    row["ReceivedDate"] = mail.ReceivedTime;
                    row["Subject"] = mail.Subject;
                    row["Body"] = mail.Body != null ? (mail.Body.Length > 25 ? mail.Body.Substring(0, 25) : mail.Body) : null;
                    //row["Body"] = mail.Body != null ? mail.Body : "";
                    row["MailSize"] = mail.Size.ToString();
                    string attachments = null;
                    if (mail.Attachments.Count > 0)
                    {
                        foreach (var attachment in mail.Attachments)
                        {
                            if (((Outlook.Attachment)attachment) != null)
                                //attachments = ((Outlook.Attachment)attachment).FileName + " " + ((Outlook.Attachment)attachment).Size.ToString() + ", ";
                                attachments += (((Outlook.Attachment)attachment).Size / 1024).ToString() + " KB, ";
                        }
                    }

                    row["AttachmentCount"] = mail.Attachments.Count;
                    if (attachments != null)
                        row["AttachmentSize"] = attachments.Substring(0, attachments.Length - 2);
                    inboxTable.Rows.Add(row);
                }
                //catch (Exception ex)
                //{
                //    return null;
                //}
            }
        }
        return inboxTable;
    }
