Question

我们有会议室预订系统，可以生成MS Outlook日历会议。

此会议将保存在MS Outlook日历中。

但是当他/她从日历打开日历邀请时，管理员无法查看跟踪菜单。 如何通过asp.net C＃启用跟踪菜单/选项？ 示例代码如下所示。

    SmtpClient sc = new SmtpClient(ConfigurationSettings.AppSettings["MailHost"].ToString());
    ClientTimeZone objClientTime = new ClientTimeZone();


        MailMessage msg = new MailMessage();


        DateTime startDuration = new DateTime();
        DateTime endDuration = new DateTime();

        LinkedResource resc = null;
        int seq_no = 0;
        bool Recurrence = false;
        bool attachment = false;
        int Recurrence_Group_ID = 0;
        string freq = "";
        string reqID = "";
        string count = "";
        string byday = "";

                    strBodyHTML = string.Format(strBodyHTML, sbBody.ToString());

                    msg.Subject = sbSubject.ToString();

                    if (IsPrivate)

        str.AppendLine(string.Format("ORGANIZER;CN=\"{0}\":MAILTO:{1}", msg.From.DisplayName, msg.From.Address));

        foreach (MailAddress strInvite in msg.To)

        AlternateView viewHTML = AlternateView.CreateAlternateViewFromString(msg.Body, new ContentType(MediaTypeNames.Text.Html));

        /*Calendar Body*/
        System.Net.Mime.ContentType ct = new System.Net.Mime.ContentType("text/calendar");
        ct.Parameters.Add("method", "REQUEST");

        msg.AlternateViews.Add(avCal);                
        // If we are using the IIS SMTP Service, we can write the message directly to the //PickupDirectory and bypass the Network Layer
        sc.DeliveryMethod = SmtpDeliveryMethod.Network;
        sc.Send(msg);

Answer 1

我不熟悉SMTP API，但可能未将此vCal项目分配给适当的用户以为其分配会议组织者角色。我会使用Exchange Web服务来创建会议请求。

日历会议请求不附带跟踪菜单
