浏览器未下载Ics文件,我已经使用iCal.NET生成了ics文件,并且代码还可以,但是ics文件不可下载。如何将其作为附件下载?我的意思是说如何使.ics文件可下载,所以我可以将其下载到磁盘上,然后通过Outlook将其打开以将其添加到日历中。
我的代码:
var calendar = new Ical.Net.Calendar();
calendar.Events.Add(new Event
{
Class = "PUBLIC",
Summary = Summary,
Created = new CalDateTime(DateTime.Now),
Description = title,
Start = new CalDateTime(Convert.ToDateTime(EventStart)),
End = new CalDateTime(Convert.ToDateTime(EventEnd)),
Sequence = 0,
Uid = Guid.NewGuid().ToString(),
Location = Location,
});
var serializer = new CalendarSerializer(new SerializationContext());
var serializedCalendar = serializer.SerializeToString(calendar);
var bytesCalendar = Encoding.UTF8.GetBytes(serializedCalendar);
return File(bytesCalendar, "text/calendar", "event.ics");
在浏览器响应中,我得到以下正确的信息:

答案 0 :(得分:0)
这是对我有用的解决方案:
StringBuilder sb = new StringBuilder();
//start the calendar item
sb.AppendLine("BEGIN:VCALENDAR");
sb.AppendLine("VERSION:2.0");
sb.AppendLine("PRODID:propertyqueen.com");
sb.AppendLine("CALSCALE:GREGORIAN");
sb.AppendLine("METHOD:PUBLISH");
//create a time zone if needed, TZID to be used in the event itself
sb.AppendLine("BEGIN:VTIMEZONE");
sb.AppendLine("BEGIN:STANDARD");
sb.AppendLine("TZID:Australia/Sydney");
sb.AppendLine("TZOFFSETTO:+1000");
sb.AppendLine("TZOFFSETFROM:+1000");
sb.AppendLine("END:STANDARD");
sb.AppendLine("END:VTIMEZONE");
//add the event
sb.AppendLine("BEGIN:VEVENT");
//without timezones
sb.AppendLine("DTSTART:" + EventStartDateTime.ToString("yyyyMMddTHHmm00"));
sb.AppendLine("DTEND:" + EventEndDateTime.ToString("yyyyMMddTHHmm00"));
sb.AppendLine("SUMMARY:" + Summary + "");
sb.AppendLine("LOCATION:" + Location + "");
sb.AppendLine("DESCRIPTION:" + Description + "");
sb.AppendLine("PRIORITY:3");
sb.AppendLine("END:VEVENT");
sb.AppendLine("END:VCALENDAR");
//send the calendar item to the browser
Response.ClearHeaders();
Response.Clear();
Response.Buffer = true;
Response.ContentType = "text/calendar";
Response.AddHeader("content-length", sb.Length.ToString());
Response.AddHeader("content-disposition", "attachment;filename=" + FileName);
Response.Write(sb.ToString());
Response.Flush();
Response.End();
var bytes = Encoding.UTF8.GetBytes(sb.ToString());
return File(bytes, "text/calendar", FileName);
