我正在使用 iCal.Net 发送会议邀请。它在 Gmail 上运行良好，它向我展示了如下事件：

谷歌邀请

但是在 Outlook 上，它没有向我显示任何邀请，例如接受、暂定和拒绝选项。它向我展示了：

展望邀请函

它应该像这样显示：

Outlook 应有的样子

这是我的代码：

async Task<SendResponse> CreateCalendarEventAsync(
        CalendarNotificationModel calendarNotificationModel)
{
var attendees = calendarNotificationModel.Attendees.Select(x => new 
Ical.Net.DataTypes.Attendee()
{
    CommonName = x.AttendeeName,
    ParticipationStatus = "REQ-PARTICIPANT",
    Rsvp = true,
    Role = "REQ-PARTICIPANT",
    Value = new Uri($"mailto:{x.AttendeeEmail}")
}).ToList();

var e = new CalendarEvent
{
    Summary = calendarNotificationModel.Name,
    IsAllDay = true,
    
    Organizer = new Organizer()
    {
        CommonName = "HRMatrix",
        Value = new Uri("mailto:xyz@zxy.com")
    },
    Attendees = attendees,
    Status = "Confirmed",
    Sequence = 0,
    Start = new CalDateTime(calendarNotificationModel.StartDateTime),
    End = new CalDateTime(calendarNotificationModel.EndDateTime),
    Transparency = TransparencyType.Opaque,
    Location = calendarNotificationModel.Location,
    Description = calendarNotificationModel.Description
};

var calendar = new Calendar();
calendar.AddProperty("X-MS-OLK-FORCEINSPECTOROPEN", "TRUE");
calendar.AddProperty("METHOD", "REQUEST");

calendar.Events.Add(e);

var serializer = new CalendarSerializer();
var serializedCalendar = serializer.SerializeToString(calendar);

var bytesCalendar = Encoding.ASCII.GetBytes(serializedCalendar);
MemoryStream ms = new MemoryStream(bytesCalendar);
using (ms)
{
    ms.Position = 0;


    SmtpClient smtp = new SmtpClient
    {
        //The address of the SMTP server (I'll take mailbox 126 as an example, which can 
be set according to the specific mailbox you use)
        Host = "smtp.gmail.com",
        EnableSsl = true,
        Port = 587,
        DeliveryMethod = SmtpDeliveryMethod.Network,
        //Enter the user name and password of your sending SMTP server here
        Credentials  = new NetworkCredential("xyz@xyz", "sdfsdfsdfsdf")
    };
    //Set default sending information
    Email.DefaultSender = new SmtpSender(smtp);
    var email = Email
        //Sender
        .From("xyz@xyz")
        //Addressee
        .To("denis@org.com")
        //Message title
        .Subject("Interview")
        //Email content
        .Body("You are invited.");
    //Determine whether the transmission is successful according to the transmission 
 result

    var attachment = new FluentEmail.Core.Models.Attachment
    {
        Data = ms,
        ContentType = "text/calendar",
        Filename = "invite.ics",
    };
    email.Attach(attachment);

    var result = email.Send();
    //Or send it asynchronously
    //await email.SendAsync();

    return result;
}

}

这是我的 .ics 文件：

 BEGIN:VCALENDAR
 METHOD:Request

 VERSION:2.0
 X-MS-OLK-FORCEINSPECTOROPEN:TRUE

PS：如果我从 Gmail 客户端发送上述 .ics 文件，它可以工作，但不能从我的 SMTP 客户端工作。

您好，您可以尝试在发送电子邮件或“mime”=>“文本/日历”时将附件字符集添加到“charset=UTF-8”；方法=请求；字符集=UTF-8'。
