c# - 如何在 Vcalendar 中动态设置“TO”字段？

Question

导出到 Vcalendar 时，我需要在“收件人”字段中设置登录用户的电子邮件地址。

public static void ExportToIcalender(HttpContext ctx, DateTime startDate, DateTime endDate, string organizer, string location, string summary, string description)
{
    string DateFormat = "yyyyMMddTHHmmssZ";
    ctx.Response.ClearContent();
    ctx.Response.ContentType = "text/calendar";
    ctx.Response.AddHeader("Content-disposition", "attachment; filename=appointment.ics");

    ctx.Response.Write("BEGIN:VCALENDAR");
    ctx.Response.Write("\nVERSION:2.0");
    ctx.Response.Write("\nMETHOD:PUBLISH");
    ctx.Response.Write("\nBEGIN:VEVENT");
    **ctx.Response.Write("\nORGANIZER:MAILTO:" + organizer);**

    ctx.Response.Write("\nDTSTART:" + startDate.ToUniversalTime().ToString(DateFormat));
    ctx.Response.Write("\nDTEND:" + endDate.ToUniversalTime().ToString(DateFormat));
    ctx.Response.Write("\nLOCATION:" + location);
    ctx.Response.Write("\nUID:" + DateTime.Now.ToUniversalTime().ToString(DateFormat) + "@mysite.com");
    ctx.Response.Write("\nDTSTAMP:" + DateTime.Now.ToUniversalTime().ToString(DateFormat));
    ctx.Response.Write("\nSUMMARY:" + summary);
    description = HtmlRemoval.StripTagsRegexCompiled(description).Replace("\r\n", "\\n");
    ctx.Response.Write("\nDESCRIPTION:" + description);
    ctx.Response.Write("\nPRIORITY:5");
    ctx.Response.Write("\nCLASS:PUBLIC");
    ctx.Response.Write("\nEND:VEVENT");
    ctx.Response.Write("\nEND:VCALENDAR");
    ctx.Response.End();
}

这条线对我没有帮助：

ctx.Response.Write("\nORGANIZER:MAILTO:" + organizer)

请提供解决方案。

您可以通过设置参加者属性来做到这一点

ctx.Response.Write("\nATTENDEE;CN=someone@email.com;RSVP=TRUE:mailto:someone@email.com");
