我正在尝试创建日历邀请并希望在附加的ICS文件中添加HTML内容。在ICS文件中为Outlook预约添加HTML

下面的代码不起作用： -

private static byte[] CreateiCal(int current_sequence, string guid, string subject, string location, DateTime startTime, DateTime endTime)

{

var a = new StringBuilder();

var sb = new StringBuilder();

a.Append("BEGIN:VCALENDAR\r\f");

a.Append("VERSION:2.0\r\f");

a.Append("PRODID:-//ince/events//NONSGML v1.0//EN\r\f");

a.Append("TZ:+00\r\f");

a.Append("BEGIN:VEVENT\r\f");

a.Append(String.Format("SEQUENCE:{0}\r\f", sequence.ToString()));

a.Append(String.Format("DTSTART:{0}\r\f", GetFormatedDate(startTime)));

a.Append(String.Format("DTEND:{0}\r\f", GetFormatedDate(endTime)));

a.Append(String.Format("LOCATION:{0}\r\f", location));

a.Append(String.Format("UID:{0}\r\f", guid));

a.Append(String.Format("SUMMARY:{0}\r\f", subject));

sb.Append("Sample Text1 \n");

sb.Append("Sample Text2 \n");

sb.Append(string.Format("Sample Text3 LINK \n", "www.google.com"));

sb.Append("Sample Text4 \n");

a.Append(String.Format("DESCRIPTION;X-ALT-DESC;FMTTYPE=text/html:"+sb.ToString() + "\r\f"));

a.Append((string.Format("ORGANIZER:MAILTO:{0}\r\f", "[email protected]")));

a.Append((string.Format("ATTENDEE;CUTYPE=INDIVIDUAL;ROLE=REQ-PARTICIPANT;PARTSTAT=NEEDS-ACTION;RSVP=FALSE;X-NUM-GUESTS=0:mailto:{0}\r\f", "[email protected]")));

a.Append(String.Format("X-MICROSOFT-CDO-APPT-SEQUENCE:{0}\r\f", current_sequence.ToString()));

a.Append("BEGIN:VALARM\r\f");

a.Append("TRIGGER:-PT15M\r\f");

a.Append("REPEAT:2\r\f");

a.Append("DURATION:PT15M\r\f");

a.Append("ACTION:DISPLAY\r\f");

a.Append("DESCRIPTION:Reminder\r\f");

a.Append("END:VALARM\r\f");

a.Append("END:VEVENT\r\f");

a.Append("END:VCALENDAR\r\f");

byte[] b = Encoding.ASCII.GetBytes(a.ToString());

return b;

}

谁能请就如何实现这一目标的一些投入？

在此先感谢。
