使用VCALENDAR和.NET的会议请求中缺少必需的与会者 [英] Missing Required Attendees in Meeting Request using VCALENDAR and .NET
问题描述
大家好，
我遇到了一个真正棘手的问题，我刚刚完全陷入了困境.我必须使用VCALENDAR格式通过电子邮件向Outlook创建会议请求.我可以整天创建.ics文件，它们可以很好地用作附件，但他们希望将其作为实际的会议要求，而不是附件.
我将使用用于发送电子邮件的代码，但问题是这样的:当我通过电子邮件发送日历时，无论我做什么，都不会显示必需"或可选"参与者.要了解我的意思，请单击此处:

Hey Everyone,
I have run into a real tough issue that I have just been completely stumped on. I have to create a meeting request via E-Mail to Outlook using the VCALENDAR format. I can create .ics files all day long and they work great as attachments, but they want it as an actual meeting request, not an attachment.
The code I use to send the email will follow, but the problem is this: When I send the calendar via email, no matter what I do, none of the "Required" or "Optional" attendees show. To see what I mean, click here:
Appointment Format[^]
Do any of you have any idea how to make this work?
Code:
System.Net.Mime.ContentType calendarType = new System.Net.Mime.ContentType("text/calendar");
// Add parameters to the calendar header
calendarType.Parameters.Add("method", "REQUEST");
calendarType.Parameters.Add("name", "meeting.ics");
MailMessage msg = new MailMessage();
AlternateView calendarView = AlternateView.CreateAlternateViewFromString(GetVCalendar().ToString(), calendarType);
//calendarView.TransferEncoding = TransferEncoding.SevenBit;
msg.AlternateViews.Add(calendarView);
msg.To.Add("some.recipient@myco.com");
msg.From = new MailAddress("my.service@myco.com");
// msg.Subject = "This time with Publish - still a problem";
// msg.Body = GetVCalendar().ToString();
string mailServer = "extrelay.myco.com";
SmtpClient client = new SmtpClient(mailServer);
client.Send(msg);
这是GetVCalendar()检索到的字符串-

推荐答案
好吧……事实证明，我们在ATTENDEE属性上缺少一个属性.有一个名为EXPECT = xxxx的属性，其中xxxx是FYI，REQUIRE，REQUEST或IMMEDIATE.
将这些添加到每个参与者后，它便可以正常工作.
Well... as it turns out, we were missing a property on the ATTENDEE property. There is a property called EXPECT=xxxx where xxxx is FYI, REQUIRE, REQUEST, or IMMEDIATE.
Once you add those to each ATTENDEE, it works perfectly.
