Question

目前，用户添加了“新的互联网日历”，但它是一次性下载ICS文件。我希望用户单击按钮以将其个人日历添加为Outlook的订阅。我希望自动更新"internet calendar subscription"。

与SharePoint一样，名为“连接到Outlook”的按钮会将您正在查看的日历添加为自动同步日历。

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

DDay.iCal是适用于.NET 2.0及更高版本Silverlight的iCal（RFC 5545）类库。它的目标是尽可能符合RFC 5545，同时针对与Apple iCal，Outlook 2007等流行的日历应用程序兼容。

iCal + MVC + DDay.iCal的一些sample code

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);
}

如何为Outlook创建“互联网日历订阅”？
