操作系统：WinXP
您用于访问Google日历的程序和版本(FF3.5)：

我正在开发一个脚本(基于我在网上找到的现有vCal ASP.NET类)来生成.ics文件.导入到Outlook 2003时,此文件可以正常工作.当我尝试导入到Google日历时,出现以下错误：

无法导入事件：无法处理您的iCal / CSV文件..

我不太了解vCal格式或语法,但一切看起来都不错.我将在下面发布示例测试日历.ics：

生成上面代码的源代码就是mvc视图::

<%@ Import Namespace ="iManageProjectPM.Controllers" %>
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<iCalendar>"%>
BEGIN:VCALENDAR
VERSION:2.0<%if (Model.Events.Count > 1)
             {%>
CALSCALE:GREGORIAN
METHOD:PUBLISH<%}%>
X-MS-OLK-FORCEINSPECTOROPEN:TRUE
<%foreach(var evnt in Model.Events){%>
BEGIN:VEVENT
DTSTART<%=Model.GetTimeString(evnt.StartTime)%>
DTEND<%=Model.GetTimeString(evnt.EndTime)%>
TRANSP:OPAQUE
SEQUENCE:0
UID:<%=evnt.UID%>
DESCRIPTION:<%=evnt.Desc%>
SUMMARY:<%=evnt.Title%>
END:VEVENT<%}%>

解决方法

ical feed的问题在于,不同的日历对于不同的东西都很挑剔,而且至少在我看来,这个规范有点难以理解.但是,Kanzaki在为像我这样的程序员制定规范方面做得很好.

现在,你的feed feed还需要精确到换行符(Apple的不会导入最后错误的换行符)并且我发现这3个验证器的组合效果最好：

>最基本的：http://severinghaus.org/projects/icv/?url=
>更好：http://icalvalid.cloudapp.net/Default.aspx
>最严格：http://ical-validator.herokuapp.com/validate/

最严格的验证器实际上对我有误报(即,它根据规范报告了实际上没有错误的错误),但是前两个没有发现错误,这就是为什么我建议通过所有三个运行您的Feed他们
