我的gmail和我的iCalendar有一个问题，这是一个简单的iCalendar:

如果我直接从gmail中附加，一切都可以工作。

如果我从我的网站发送，它不会。

这里是我的代码:

        using (var smtp = new SmtpClient())
        {
            var subject = "Confirm";
            var message = new MailMessage();
            message.To.Add(email);
            message.Subject = subject;
            var loCalendarType = new System.Net.Mime.ContentType();
            loCalendarType.MediaType = "text/calendar";
            loCalendarType.Parameters.Add("method", "REQUEST");
            loCalendarType.CharSet = @"""utf-8""";
            loCalendarType.Name = "event.ics";
            // Create message body parts
            var loCalendarView = AlternateView.CreateAlternateViewFromString(ical, loCalendarType);
            loCalendarView.TransferEncoding = System.Net.Mime.TransferEncoding.SevenBit;
            message.AlternateViews.Add(loCalendarView);
            // html
            message.AlternateViews.Add(AlternateView.CreateAlternateViewFromString(html, Encoding.UTF8, System.Net.Mime.MediaTypeNames.Text.Html));
            smtp.Send(message);
        }

，这是mime发送:

我几乎读了所有关于它的东西，但是我真的不知道我的代码出了什么问题。它总是像附件一样显示，而不是像约会。

为什么我的icalcalendar不能被gmail识别?

你确定吗?运行你的代码，我得到两个基本错误。您需要提供一个from地址，而utf8行会导致问题。把它注释掉。这两个问题解决后，生成的邮件被gmail正确地解释为邀请。

日历，是从我最初问的这个问题复制过来的，很好。Gmail没有Outlook那么挑剔。

刚刚更改了我的SMTP凭据，一切正常…2天的工作…wtf gmail

<mailSettings>
  <!-- NOT WORKING
<smtp from="xxx@gmail.com">
    <network host="smtp.gmail.com" port="587" enableSsl="true" userName="xxx@gmail.com" password="yyy" />
  </smtp>-->
  <smtp from="info@something.else">
    <network host="mail.something.else" userName="info@something.else" password="yyy" />
  </smtp>
</mailSettings>

我代码:

using (var smtp = new SmtpClient())
{   
    var message = new MailMessage();
    message.To.Add(email);
    message.Subject = "Subject";
    // HTML
    message.AlternateViews.Add(AlternateView.CreateAlternateViewFromString(html, Encoding.UTF8, System.Net.Mime.MediaTypeNames.Text.Html));
    // VCARD
    System.Net.Mime.ContentType loCalendarType = new System.Net.Mime.ContentType("text/calendar; method=REQUEST");
    AlternateView icalView = AlternateView.CreateAlternateViewFromString(ical, loCalendarType);
    icalView.TransferEncoding = TransferEncoding.Base64;
    message.AlternateViews.Add(icalView);
    smtp.Send(message);
}
