asp.net-mvc-4 - 如何为 Outlook 创建 "internet calendar subscription"？

Question

目前，用户添加了“新的 Internet 日历”，但它是一次性下载 ICS 文件。我希望用户单击一个按钮将他的个人日历添加为 Outlook 订阅。我要自动更新 "internet calendar subscription" .

就像在 SharePoint 中一样，名为“连接到 Outlook”的按钮会将您正在查看的日历作为自动同步日历添加到您的 Outlook 中。

Creating iCals in C#和 this CodeProject post告诉我你应该使用 DDay iCal Library .

DDay.iCal is an iCal (RFC 5545) class library for .NET 2.0 and above, Silverlight. It aims at being as RFC 5545 compliant as possible, while targeting compatibility with popular calendaring applications, like Apple iCal, Outlook 2007, etc.

一些 sample code iCal + MVC + DDay.iCal

public ActionResult iCalendar(string DownloadFileName)
{
    DDay.iCal.iCalendar iCal = new DDay.iCal.iCalendar();

    Event evt = iCal.Create<Event>();
    evt.Start = iCalDateTime.Today.AddHours(8);
    evt.End = evt.Start.AddHours(18); // This also sets the duration
    evt.Description = "The event description";
    evt.Location = "Event location";
    evt.Summary = "18 hour event summary";

    evt = iCal.Create<Event>();
    evt.Start = iCalDateTime.Today.AddDays(5);
    evt.End = evt.Start.AddDays(1);
    evt.IsAllDay = true;
    evt.Summary = "All-day event";

    ISerializationContext ctx = new SerializationContext();
    ISerializerFactory factory = new DDay.iCal.Serialization.iCalendar.SerializerFactory();
    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, DownloadFileName);
}
