我正在使用C#中的ASP.NET MVC 1框架创建一个应用程序,其中我有用户注册事件。注册后,我创建了一个Outlook会议请求
public string BuildMeetingRequest(DateTime start, DateTime end, string attendees, string organizer, string subject, string description, string UID, string location)
{
System.Text.StringBuilder sw = new System.Text.StringBuilder();
sw.AppendLine("BEGIN:VCALENDAR");
sw.AppendLine("VERSION:2.0");
sw.AppendLine("METHOD:REQUEST");
sw.AppendLine("BEGIN:VEVENT");
sw.AppendLine(attendees);
sw.AppendLine("CLASS:PUBLIC");
sw.AppendLine(string.Format("CREATED:{0:yyyyMMddTHHmmssZ}", DateTime.UtcNow));
sw.AppendLine("DESCRIPTION:" + description);
sw.AppendLine(string.Format("DTEND:{0:yyyyMMddTHHmmssZ}", end));
sw.AppendLine(string.Format("DTSTAMP:{0:yyyyMMddTHHmmssZ}", DateTime.UtcNow));
sw.AppendLine(string.Format("DTSTART:{0:yyyyMMddTHHmmssZ}", start));
sw.AppendLine("ORGANIZER;CN=\"NAME\":mailto:" + organizer);
sw.AppendLine("SEQUENCE:0");
sw.AppendLine("UID:" + UID);
sw.AppendLine("LOCATION:" + location);
sw.AppendLine("SUMMARY;LANGUAGE=en-us:" + subject);
sw.AppendLine("BEGIN:VALARM");
sw.AppendLine("TRIGGER:-PT720M");
sw.AppendLine("ACTION:DISPLAY");
sw.AppendLine("DESCRIPTION:Reminder");
sw.AppendLine("END:VALARM");
sw.AppendLine("END:VEVENT");
sw.AppendLine("END:VCALENDAR");
return sw.ToString();
}
一旦构建,我使用MailMessage,并使用备用视图发送会议请求:
meetingInfo = BuildMeetingRequest(start, end, attendees, organizer, subject, description, UID, location);
System.Net.Mime.ContentType mimeType = new System.Net.Mime.ContentType("text/calendar; method=REQUEST");
AlternateView ICSview = AlternateView.CreateAlternateViewFromString(meetingInfo,mimeType);
MailMessage message = new MailMessage();
message.To.Add(to);
message.From = new MailAddress(from);
message.AlternateViews.Add(ICSview);
SmtpClient client = new SmtpClient();
client.Send(message);
当用户在Outlook中收到电子邮件时,它会显示为会议请求,而不是普通电子邮件。
这也适用于发送会议请求的更新。我遇到的唯一问题是我不知道发送取消的正确格式。我试图在文本编辑器中检查一些会议请求取消,但似乎无法确定取消/创建之间格式的差异。
非常感谢任何帮助。
