C# ICalendar（ICS）-只有VEVENT组件可以与outlook/googleCalendar配合使用

我在生成Icalendar文件（*.ICS）时遇到一些问题 我正在使用Ical.NET和c语言库

代码非常简单，例如这是VEVENT：

  public override void HandleComponent(Ical.Net.Calendar root, CalendarData data)
  {
            var icalEvent = new Ical.Net.Event();
            icalEvent.Start = new CalDateTime(data.Poczatek);
            icalEvent.End = new CalDateTime(data.Koniec);
            icalEvent.Location = data.Lokalizacja;
            icalEvent.Description = data.Opis;
            icalEvent.Summary = data.Nazwa;
            root.Events.Add(icalEvent);
  }

Vtravely和VTODO的代码非常相似您的代码很可能很好。但你需要问问自己，通过尝试在谷歌日历中导入这些VJOURNAL和VTODO，你真正希望做什么？ 到目前为止，Google日历实际上只支持活动/会议：

• 它不支持VJOURNAL。事实上，真正支持VJOURNAL的软件很少。从它的定义（）中，您将看到它可以被视为博客条目的祖先
• 它也不支持VTODO。你能找到的最接近的是Gmail，它有一个任务列表的概念

更重要的是验证：表示文件已正确创建

var serializer = new CalendarSerializer(calendar);
var icsContent = serializer.SerializeToString();
return icsContent;
