在Sendgrid中附加ics文件
如何在C＃中使用Sendgrid发送日历邀请？在Sendgrid中附加ics文件
我可以将ics文件附加到邮件中，但是当我下载附件时，出现“无效日历文件”错误。
string CalendarContent = "BEGIN:VCALENDAR VERSION:2.0 PRODID:-//Meeter/meeter//NONSGML v1.0//EN CALSCALE:GREGORIAN METHOD:REQUEST BEGIN:VEVENT DTSTART:20141018T203000Z DTEND:20141018T210000Z UID:[email protected] DTSTAMP:20141014T212813Z ORGANIZER;CN=\"[email protected]\";SENT-BY=\"MAILTO:[email protected]\";LANGUAGE=se:MAILTO:[email protected] ATTENDEE;CUTYPE=INDIVIDUAL;ROLE=REQ-PARTICIPANT;PARTSTAT=NEEDS-ACTION;RSVP=TRUE;CN=Fessy M;X-NUM-GUESTS=0:MAILTO:[email protected] DESCRIPTION:dddd mandrill LOCATION:dddddd mandrill SUMMARY:Can I lay low? Cook some yay-yo 2 TRANSP:OPAQUE SEQUENCE:0 STATUS:CONFIRMED END:VEVENT END:VCALENDAR";
using (MemoryStream ms = new MemoryStream(Encoding.ASCII.GetBytes(CalendarContent)))
{
_Message.AddAttachment(ms, "meeting.ics");
}
var Header = new Dictionary<string, string>();
Header.Add("Content-Type", "text/calendar");
如果你试图发送一个日历，你需要做到以下几点：
// you already have the _Message & CalendarContent created above
// first thing, convert calendar content to byte array and then stream
byte[] calendarBytes = Encoding.UTF8.GetBytes(CalendarContent.ToString());
Stream calendarStream = new MemoryStream(calendarBytes);
// them create a attachment for your mail message
Attachment calendarAttachment = new Attachment(calendarStream, "calendar.ics", "text/calendar");
calendarAttachment.TransferEncoding = System.Net.Mime.TransferEncoding.Base64;
// now attach the calendar to your Mail Message
_Message.Attachments.Add(calendarAttachment);
// now send the message off
无法添加上面的附件。文档说你必须使用'AddAttachment（）'方法。但是，然后，我无法设置MimeType – Belicosus
此答案似乎使用SMTPClient和System.Net.Mail类使用SendGrid凭据发送电子邮件。原来的问题似乎是使用SendGrid C＃客户端API库之一。这就是为什么Belicosus说文档使用AddAttachment（）并且Black Frog提供的答案使用_Message.Attachments.Add（） –
有几件事情。
首先CalendarContent看起来不合法，它没有任何换行符。
首先尝试：
string CalendarContent = @"BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//Meeter/meeter//NONSGML v1.0//EN
CALSCALE:GREGORIAN
METHOD:REQUEST
BEGIN:VEVENT
DTSTART:20141018T203000Z
DTEND:20141018T210000Z
UID:[email protected]
DTSTAMP:20141014T212813Z
ORGANIZER;CN=\"[email protected]\";SENT-BY=\"MAILTO:[email protected]\";LANGUAGE=se:MAILTO:[email protected]
ATTENDEE;CUTYPE=INDIVIDUAL;ROLE=REQ-PARTICIPANT;PARTSTAT=NEEDS-ACTION;RSVP=TRUE;CN=Fessy M;X-NUM-GUESTS=0:MAILTO:[email protected]
DESCRIPTION:dddd mandrill
LOCATION:dddddd mandrill
SUMMARY:Can I lay low? Cook some yay-yo 2
TRANSP:OPAQUE
SEQUENCE:0
STATUS:CONFIRMED
END:VEVENT
END:VCALENDAR";
如果不工作，它会出现以下不遵循RFC 5545但我不看好这一点，RFC可能会造成混淆：
ORGANIZER;CN=\"[email protected]\";SENT-BY=\"MAILTO:[email protected]\";LANGUAGE=se:MAILTO:[email protected]
ATTENDEE;CUTYPE=INDIVIDUAL;ROLE=REQ-PARTICIPANT;PARTSTAT=NEEDS-ACTION;RSVP=TRUE;CN=Fessy M;X-NUM-GUESTS=0:MAILTO:[email protected]
可能是：
ORGANIZER;LANGUAGE=se:SENT-BY=\"mailto:[email protected]\":mailto:[email protected]
ATTENDEE;CUTYPE=INDIVIDUAL;ROLE=REQ-PARTICIPANT;PARTSTAT=NEEDS-ACTION;RSVP=TRUE;CN=Fessy M;X-NUM-GUESTS=0:mailto:[email protected]
你们是不是要发送日历通过电子邮件邀请或从网页上下载？ –
