Question

我要求使用html正文Tag发送会议请求。我已成功发送会议请求，它可以正常工作。

这是ICS文件格式

我发现了一些链接，可以通过X-ALT-DESC选项发送html链接，但它对我不起作用

Send an Outlook Meeting Request with C#

Send email to Outlook with ics meeting appointment

以下是使用ICS文件发送电子邮件的C＃代码

filePath = Path.Combine(HttpRuntime.AppDomainAppPath, "Email/calenderInvitation.ics");
                fileContent = System.IO.File.OpenText(filePath).ReadToEnd();
                fileContent = fileContent.Replace("#TO#", receiver);
                fileContent = fileContent.Replace("#FROM#", fromAddress.Address);
                fileContent = fileContent.Replace("#LOCATION#", eventVenue);
                fileContent = fileContent.Replace("#UID#", Guid.NewGuid().ToString().Replace("-", ""));
                fileContent = fileContent.Replace("#CREATED-AT#", Convert.ToDateTime(meetingDate).ToString(TimeFormat));
                fileContent = fileContent.Replace("#DTSTART#", Convert.ToDateTime(startTime).ToString(TimeFormat));
                fileContent = fileContent.Replace("#DTEND#", Convert.ToDateTime(finishTime).ToString(TimeFormat));
                filePath = Path.Combine(HttpRuntime.AppDomainAppPath, "Email/InvitationEmail.html");
                fileInviationContent = System.IO.File.OpenText(filePath).ReadToEnd();
                String body = AppendRedirectURl(fileInviationContent, callBackUrl);
                fileContent = fileContent.Replace("#X-ALT-DESC#", body);
                MailMessage message = new MailMessage();
               // message.IsBodyHtml = true;
                message.From = new MailAddress(fromAddress.Address);
                message.To.Add(new MailAddress(receiver));
                message.Subject = string.Format("{0}  {1} @ {2} {3} {4} {5} - {6}", "Invitation: ", meetingTypeName,
                    Convert.ToDateTime(meetingDate).ToString("dddd"), Convert.ToDateTime(startTime).ToString("MMMM"),
                    Convert.ToDateTime(startTime).ToString("yyyy"), startTime,
                    finishTime);

                var iCalendarContentType = new ContentType("text/calendar; method=REQUEST");
                var calendarView = AlternateView.CreateAlternateViewFromString(fileContent, iCalendarContentType);
                calendarView.TransferEncoding = TransferEncoding.SevenBit;
                message.AlternateViews.Add(calendarView);
                await smtp.SendMailAsync(message);

这是调试器响应

我在此链接（visual basic）https://social.msdn.microsoft.com/Forums/en-US/2cd0dcff-7d6c-493e-bf49-87a3e3248d01/create-meeting-request-with-html-body-in-aspnet?forum=netfxnetcom

找到了解决方案

基本上，您添加第二个AlternateView。以下是我的表现。我的身体＆＃34;字符串有我的HTML。我确实注意到如果我添加＆＃34; avCalendar＆＃34;我的会议在Outlook中被破坏了。之前＆＃34; avHtmlBody＆＃34;。所以我猜这个命令很重要。

在我的meetingRequestString中，我删除了DESCRIPTION和X-ALT-DESC的部分。

MailMessage msg = new MailMessage(from, to);

var htmlContentType = new System.Net.Mime.ContentType(System.Net.Mime.MediaTypeNames.Text.Html);
var avHtmlBody = AlternateView.CreateAlternateViewFromString(body, htmlContentType);
msg.AlternateViews.Add(avHtmlBody);

string meetingRequestString = GetMeetingRequestString(from, to, subject, body, startTime, endTime);
System.Net.Mime.ContentType ct = new System.Net.Mime.ContentType("text/calendar");
ct.Parameters.Add("method", "REQUEST");
ct.Parameters.Add("name", "meeting.ics");
AlternateView avCalendar = AlternateView.CreateAlternateViewFromString(meetingRequestString, ct);
msg.AlternateViews.Add(avCalendar);
client.Send(msg);

通过会议邀请C＃发送Html
