C# 什么是为体育赛事服务的正确方式？

我试图允许用户使用将在线日历中的事件添加到设备上的日历中。这在iOS和桌面平台上似乎很好，但我在安卓设备上遇到了障碍。我遇到这样的信息：

有没有更好的方式来为这项活动服务，从而避免这种情况发生

public ActionResult ICS(int id)
{
        // Get event from Database
        var heEvent = HEEvent.GetEventDetails(id);

        // Create iCal object
        var iCal = new iCalendar();
        iCal.Method = "PUBLISH";

        // Create iCal Event
        var icalEvent = iCal.Create<DDay.iCal.Event>();
        icalEvent.Summary = heEvent.Name;
        icalEvent.Start = new iCalDateTime(heEvent.TimeBegin.Year, heEvent.TimeBegin.Month, heEvent.TimeBegin.Day, heEvent.TimeBegin.Hour, heEvent.TimeBegin.Minute, 00);

        TimeSpan calculatedEventDuration = heEvent.DateEnd.Subtract(heEvent.TimeBegin);
        if (calculatedEventDuration.Hours > 1) { icalEvent.Duration = calculatedEventDuration; }
        else { icalEvent.Duration = TimeSpan.FromHours(1); } // default to 1 hour if event time is less

        icalEvent.Location = heEvent.Location;

        // Create a serialization context and serializer factory.
        // These will be used to build the serializer for our object.
        ISerializationContext ctx = new SerializationContext();
        ISerializerFactory factory = new DDay.iCal.Serialization.iCalendar.SerializerFactory();
        // Get a serializer for our object
        IStringSerializer serializer = factory.Build(iCal.GetType(), ctx) as IStringSerializer;

        string output = serializer.SerializeToString(iCal);
        var contentType = "text/calendar";
        var bytes = Encoding.UTF8.GetBytes(output);

        return File(bytes, contentType, String.Format(@"{0}.ics", heEvent.Name.Replace(" ", "_")));
}

你的错误，你不需要我告诉你，与我无关。这完全取决于你、你的手机和你的技术预算。买一张SD卡

关于服务Icalendar，您经常听到它们被称为feed，但是订阅Icalendar的客户端定期轮询日历url，每次都请求整个日历。为了避免大量不必要的处理，您需要以某种方式持久化日历，以便在不重新生成数千次相同日历的情况下传播更改。为此，我建议使用文件系统和HTTP缓存头。修改日历时，将其作为静态文件写入面向web的目录中。也许你已经这么做了。然后在您的Web服务器上设置合理的缓存头，然后离开
