我有一个 ASP.Net MVC 4 应用程序正在下载一个空文件。我错过了什么?
控制器:
public class HomeController : Controller
{
public ActionResult Index()
{
return View();
}
public FileStreamResult ICS()
{
var memoryStream = new MemoryStream();
StreamWriter sw = new StreamWriter(memoryStream);
sw.WriteLine(@"BEGIN:VCALENDAR");
sw.WriteLine(@"VERSION:2.0");
sw.WriteLine(@"PRODID:-//www.marudot.com//iCal Event Maker");
sw.WriteLine(@"BEGIN:VEVENT");
sw.WriteLine(@"DTSTAMP:20141111T165545Z");
sw.WriteLine(@"UID:20141111T165545Z-1194755835@marudot.com");
sw.WriteLine(@"DTSTART;TZID=""America/Chicago"":20141114T080000");
sw.WriteLine(@"DTEND;TZID=""America/Chicago"":20141114T120000");
sw.WriteLine(@"SUMMARY:Bobby's Big Bash");
sw.WriteLine(@"DESCRIPTION:test");
sw.WriteLine(@"LOCATION:test");
sw.WriteLine(@"END:VEVENT");
sw.WriteLine(@"END:VCALENDAR");
sw.Flush();
return new FileStreamResult(memoryStream, "text/calendar") { FileDownloadName = "test.ics" };
}
}
看法:
<h2>Index</h2>
@Html.ActionLink("ical event", "ICS");
单击该链接会下载一个空的 ICS 文件。
