从自动保存到客户端 Outlook 日历的 ASP.Net 发送邮件

我只想从我的 ASP.Net 应用程序向Outlook发送一封提醒邮件，该邮件会自动保存到目标Outlook Emailid calandar。

我已经实现了这个，但这仅适用于我的系统的 Outlook。它不适用于其他系统。

protected void btSent_Click(object sender, EventArgs e) { SendMail("xyz@xyz.com", "xyx"); } public void SendMail(string targetMail, string shownTargetName) { MailAddress fromAddress = new MailAddress("xyz@xyz.com", "MailSendingProgram"); MailAddress toAddress = new MailAddress(targetMail, shownTargetName); String fromPassword = "xyz"; String subject = "Test Recurrence"; String body = @" Here you can put in any text that will appear in the body multilined and even in "; SmtpClient smtp = new SmtpClient { Host = "smtp.xyz.com", Port = 25, EnableSsl = true, DeliveryMethod = SmtpDeliveryMethod.Network, UseDefaultCredentials = false, Credentials = new NetworkCredential(fromAddress.Address, fromPassword) };
    using (MailMessage message = new MailMessage(fromAddress, toAddress)
    {
        Subject = subject,
        Body = body
    }
          )
    {
        try
        {
            ServicePointManager.ServerCertificateValidationCallback = delegate(object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
                 { return true; };
            smtp.Send(message);
            lbError.Text = "E-Mail sent!";
            Microsoft.Office.Interop.Outlook.Application olApp = new Microsoft.Office.Interop.Outlook.Application();
            CreateNewRecurringAppointment(olApp);
            Marshal.ReleaseComObject(olApp);
        }
        catch
        {
            lbError.Text = "Sending failed, check your internet connection!";
        }
    }
}
public void CreateNewRecurringAppointment(Microsoft.Office.Interop.Outlook._Application OutlookApp) { Microsoft.Office.Interop.Outlook.AppointmentItem appItem = null; Microsoft.Office.Interop.Outlook.RecurrencePattern pattern = null; try { appItem = OutlookApp.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olAppointmentItem) as Microsoft.Office.Interop.Outlook.AppointmentItem; // create a recurrence pattern = appItem.GetRecurrencePattern(); pattern.RecurrenceType = Microsoft.Office.Interop.Outlook.OlRecurrenceType.olRecursWeekly; pattern.StartTime = DateTime.Parse("8:35:00 AM"); pattern.EndTime = DateTime.Parse("9:35:00 PM"); // we can specify the duration instead of using the EndTime property pattern.Duration = 60; pattern.PatternStartDate = DateTime.Parse("03/9/2015"); pattern.PatternEndDate = DateTime.Parse("03/9/2015"); appItem.Subject = "Meeting with the Boss"; appItem.Body = "Test Appointment body"; appItem.Location = "P1"; appItem.ReminderSet = true; appItem.ReminderMinutesBeforeStart = 15; appItem.Importance = Microsoft.Office.Interop.Outlook.OlImportance.olImportanceHigh; appItem.BusyStatus = Microsoft.Office.Interop.Outlook.OlBusyStatus.olBusy; appItem.Save(); appItem.Send();
        //appItem.Display(true);
    }
    catch (Exception ex)
    {
        lbRecur.Text = ex.Message;
    }
    finally
    {
        if (pattern != null)
        {
            System.Runtime.InteropServices.Marshal.ReleaseComObject(pattern);
        }
        if (appItem != null)
        {
            System.Runtime.InteropServices.Marshal.ReleaseComObject(appItem);
        }
    }
}

Microsoft 当前不建议也不支持从任何无人参与、非交互式客户端应用程序或组件（包括 ASP、ASP.NET、DCOM 和 NT 服务）自动化Microsoft Office 应用程序，因为在此环境中运行 Office 时 Office 可能会表现出不稳定的行为和/或死锁。

如果要生成在服务器端上下文中运行的解决方案，则应尝试使用已安全执行无人参与的组件。或者，您应该尝试找到至少允许部分代码在客户端运行的替代方法。如果使用服务器端解决方案中的 Office 应用程序，则该应用程序将缺少成功运行所需的许多功能。此外，您将承担整体解决方案稳定性的风险。可以在 Office 服务器端自动化的注意事项一文中阅读有关此内容的详细信息。

请考虑使用 EWS（Exchange Web 服务）或 BCL（基类库）中的标准类。您可能会发现 Exchange 中的 EWS 托管 API、EWS 和 Web 服务文章很有帮助。
