Question

如何创建一个包含最少数据的icalendar文件，我尝试将其设为以下但有些错误，当我尝试导入到我的Google日历时，它说事件已成功导入但我无法在我的日历上看到这些事件

    strResult.Append("BEGIN:VCALENDAR" & vbCrLf)           

    strResult.Append("VERSION:2.0" & vbCrLf)

    strResult.Append("METHOD:PUBLISH" & vbCrLf)

    While rst1.Read
        strResult.Append("BEGIN:VEVENT" & vbCrLf)

        strResult.Append("DTSTART: " & CDate(getLeave_date_start(CStr(rst1.getInteger("inq_id")), g_dom_id)).ToUniversalTime().ToString("yyyyMMddTHHmmssZ") & vbCrLf)    

        strResult.Append("DTEND: " & CDate(getLeave_date_end(CStr(rst1.getInteger("inq_id")), g_dom_id)).ToUniversalTime().ToString("yyyyMMddTHHmmssZ") & vbCrLf)

        strResult.Append("SUMMARY: " & rst1.getString("inq_name") & vbCrLf)

        strResult.Append("UID: " & rst1.getInteger("inq_id") & vbCrLf)

        strResult.Append("CLASS:PUBLIC" & vbCrLf)

        strResult.Append("END:VEVENT" & vbCrLf)

    End While
    strResult.Append("END:VCALENDAR" & vbCrLf)

    WriteCalendar(strResult)

我写了一个函数WriteCalendar，如下所示

Private Sub WriteCalendar(ByVal data As String)
    Dim response As HttpResponse = Page.Response
    response.Clear()
    response.Buffer = True
    response.ContentType = "text/calendar"
    response.ContentEncoding = Encoding.UTF8
    response.Charset = "utf-8"
    response.AddHeader("Content-Disposition", "attachment;filename=""" & "icalendarTest" & ".ics""")
    response.Write(data)
    response.[End]()
End Sub

我下载该文件并查看我的活动，但在导入到Google日历时，它表示已成功导入6个事件，但我无法在我的日历上看到它们

输出icalendarTest.ics

BEGIN:VCALENDAR  
VERSION:2.0  
METHOD:PUBLISH

我没有在.ics中包含所有标签，这就是这个错误的原因。

我从Google日历中提取了自己的日历并包含了缺失的数据，现在可以使用了。 DTSTAMP似乎是必需的，虽然我发现它是不合适的，但只要它有效就可以了

    strResult.Append("BEGIN:VCALENDAR" & vbCrLf)
    strResult.Append("PRODID:-//Google Inc//Google Calendar 70.9054//EN" & vbCrLf)
    strResult.Append("VERSION:2.0" & vbCrLf)
    strResult.Append("METHOD:PUBLISH" & vbCrLf)

    While rst1.Read
        strResult.Append("BEGIN:VEVENT" & vbCrLf)
        strResult.Append("DTSTART:" & rst1.getDateTime("hly_startdate").ToUniversalTime().ToString("yyyyMMddTHHmmssZ") & vbCrLf)
        strResult.Append("DTEND:" & rst1.getDateTime("hly_enddate").ToUniversalTime().ToString("yyyyMMddTHHmmssZ") & vbCrLf)
        strResult.Append("DTSTAMP:" & rst1.getDateTime("hly_date_created").ToUniversalTime().ToString("yyyyMMddTHHmmssZ") & vbCrLf)
        strResult.Append("SEQUENCE:0" & vbCrLf)
        strResult.Append("STATUS:CONFIRMED" & vbCrLf)
        strResult.Append("SUMMARY:" & rst1.getString("hly_name") & vbCrLf)
        strResult.Append("UID:" & System.Guid.NewGuid.ToString() & vbCrLf)
        strResult.Append("CLASS:PUBLIC" & vbCrLf)
        strResult.Append("TRANSP:OPAQUE" & vbCrLf)
        strResult.Append("END:VEVENT" & vbCrLf)

    End While
    strResult.Append("END:VCALENDAR" & vbCrLf)

如何以编程方式创建.ics文件？
