  为了确保我理解您的问题，您希望在Web应用程序上提供“下载为.ical”按钮，并使用您应用程序中的特定日历事件数据动态填充？

  将一个ical文件（或更准确地说，一个.ics文件）想象成一个字符串，但使用不同的Mime类型 . 以下描述了iCalendar格式的基础知识：

  在ASP.NET中，我需要提供完整的网页 . 在处理程序中，用这样的东西替换ProcessRequest方法（信用转到http://webdevel.blogspot.com/2006/02/how-to-generate-icalendar-file-aspnetc.html）

  private string DateFormat
  {
      get { return "yyyyMMddTHHmmssZ"; } // 20060215T092000Z
  }
  
  public void ProcessRequest(HttpContext context)
  {
      DateTime startDate = DateTime.Now.AddDays(5);
      DateTime endDate = startDate.AddMinutes(35);
      string organizer = "foo@bar.com";
      string location = "My House";
      string summary = "My Event";
      string description = "Please come to\\nMy House";
  
      context.Response.ContentType="text/calendar";
      context.Response.AddHeader("Content-disposition", "attachment; filename=appointment.ics");
  
      context.Response.Write("BEGIN:VCALENDAR");
      context.Response.Write("\nVERSION:2.0");
      context.Response.Write("\nMETHOD:PUBLISH");
      context.Response.Write("\nBEGIN:VEVENT");
      context.Response.Write("\nORGANIZER:MAILTO:" + organizer);
      context.Response.Write("\nDTSTART:" + startDate.ToUniversalTime().ToString(DateFormat));
      context.Response.Write("\nDTEND:" + endDate.ToUniversalTime().ToString(DateFormat));
      context.Response.Write("\nLOCATION:" + location);
      context.Response.Write("\nUID:" + DateTime.Now.ToUniversalTime().ToString(DateFormat) + "@mysite.com");
      context.Response.Write("\nDTSTAMP:" + DateTime.Now.ToUniversalTime().ToString(DateFormat));
      context.Response.Write("\nSUMMARY:" + summary);
      context.Response.Write("\nDESCRIPTION:" + description);
      context.Response.Write("\nPRIORITY:5");
      context.Response.Write("\nCLASS:PUBLIC");
      context.Response.Write("\nEND:VEVENT");
      context.Response.Write("\nEND:VCALENDAR");
      context.Response.End();
  }
