I need to create Google Calendar Events using ASP.NET. Requirement: On click of a button, the event details will be captured like Start Time, End Time, Agenda, Email IDs of attendees and the event will be created in Google Calendar.
Please help.
Thanks in advance.
You need to create a eMail formatted to send to your contact, or anything you want, hope it helps :)
public void SendAppointment()
{
try
{
MailMessage msg = new MailMessage();
SmtpClient sc = new SmtpClient("smtp.gmail.com", 587);
msg.From = new MailAddress("[email protected]", "NEW EVENT");
sc.Credentials = new NetworkCredential("[email protected]", "password");
sc.EnableSsl = true;
msg.To.Add(new MailAddress("[email protected]", "Invited"));
msg.Subject = "Subject";
msg.Body = "YOUR CONTENT";
StringBuilder str = new StringBuilder();
str.AppendLine("BEGIN:VCALENDAR");
str.AppendLine("PRODID:-//GeO");
str.AppendLine("VERSION:2.0");
str.AppendLine("METHOD:REQUEST");
str.AppendLine("BEGIN:VEVENT");
str.AppendLine(string.Format("DTSTART:{0:yyyyMMddTHHmmssZ}", START_DATE));
str.AppendLine(string.Format("DTSTAMP:{0:yyyyMMddTHHmmssZ}", DateTime.UtcNow));
str.AppendLine(string.Format("DTEND:{0:yyyyMMddTHHmmssZ}", END_DATE));
str.AppendLine("LOCATION: " + Direccion);
str.AppendLine(string.Format("UID:{0}", Guid.NewGuid()));
//str.AppendLine(string.Format("DESCRIPTION:{0}", msg.Body));
str.AppendLine(string.Format("DESCRIPTION;ENCODING=QUOTED-PRINTABLE:{0}", msg.Body));
str.AppendLine(string.Format("X-ALT-DESC;FMTTYPE=text/html:{0}", msg.Body));
str.AppendLine(string.Format("SUMMARY;ENCODING=QUOTED-PRINTABLE:{0}", msg.Subject));
str.AppendLine(string.Format("ORGANIZER:MAILTO:{0}", msg.From.Address));
str.AppendLine(string.Format("ATTENDEE;CN=\"{0}\";RSVP=TRUE:mailto:{1}", msg.To[0].DisplayName, msg.To[0].Address));
str.AppendLine("BEGIN:VALARM");
str.AppendLine("TRIGGER:-PT15M");
str.AppendLine("ACTION:DISPLAY");
str.AppendLine("DESCRIPTION;ENCODING=QUOTED-PRINTABLE:Reminder");
str.AppendLine("END:VALARM");
str.AppendLine("END:VEVENT");
str.AppendLine("END:VCALENDAR");
System.Net.Mime.ContentType type = new System.Net.Mime.ContentType("text/calendar");
type.Parameters.Add("method", "REQUEST");
//type.Parameters.Add("method", "PUBLISH");
type.Parameters.Add("name", "Cita.ics");
msg.AlternateViews.Add(AlternateView.CreateAlternateViewFromString(str.ToString(), type));
sc.Send(msg);
}
catch (Exception e)
{
throw e;
}
}
That you want is an iCalendar file. Please look here http://en.wikipedia.org/wiki/ICalendar. and here Creating iCal Files in c#
