我怎样才能prevent从邮件正文中显示的附件内容？ [英] How can i prevent the attachment content from displaying in the body of the message?

问题描述

我正在发送一封电子邮件，一个附件一个asp.net C＃应用程序。
附件是一个vCalendar文件。
这里的code：

I'm working on an asp.net c# application that sends an email with one attachment. The attachment is a vCalendar file. Here's the code:

            StringBuilder sbCalendar = new StringBuilder();
            DateTime dtStart = eventDate;
            DateTime dtEnd = eventDate;

            sbCalendar.AppendLine("METHOD: REQUEST");
            sbCalendar.AppendLine("BEGIN:VCALENDAR");
            sbCalendar.AppendLine("PRODID:-//DP//NET");
            sbCalendar.AppendLine("MIMEDIR//ENVERSION:1.0");
            sbCalendar.AppendLine("METHOD:REQUEST");
            sbCalendar.AppendLine("BEGIN:VEVENT");
            sbCalendar.AppendLine("DTSTAMP:" + dtStart.ToUniversalTime().ToString("yyyyMMdd\\THHmmss\\Z"));
            sbCalendar.AppendLine("DTSTART:" + dtStart.ToUniversalTime().ToString("yyyyMMdd\\THHmmss\\Z"));
            sbCalendar.AppendLine("DTEND:" + dtEnd.ToUniversalTime().ToString("yyyyMMdd\\THHmmss\\Z"));
            sbCalendar.AppendLine("LOCATION:" + eventLocation);
            sbCalendar.AppendLine("DESCRIPTION;ENCODING=QUOTED-PRINTABLE:" + eventBody);
            sbCalendar.AppendLine("SUMMARY:" + eventSubject);
            sbCalendar.AppendLine("PRIORITY:3");
            sbCalendar.AppendLine("UID:" + Guid.NewGuid().ToString());
            sbCalendar.AppendLine("ATTENDEE;ROLE=REQ-PARTICIPANT;PARTSTAT=NEEDS-ACTION:MAILTO:[e-mail]");
            sbCalendar.AppendLine("ATTENDEE;ROLE=CHAIR;PARTSTAT=ACCEPTED:MAILTO:[e-mail]");
            sbCalendar.AppendLine("CLASS:PUBLIC");
            sbCalendar.AppendLine("ORGANIZER:MAILTO:[e-mail]");
            sbCalendar.AppendLine("SEQUENCE:0");
            sbCalendar.AppendLine("STATUS:TENTATIVE");
            sbCalendar.AppendLine("END:VEVENT");
            sbCalendar.AppendLine("END:VCALENDAR");

            byte[] byteArray = Encoding.UTF8.GetBytes(sbCalendar.ToString());

            Stream contentStream = new MemoryStream(byteArray);

            SmtpClient smtp = new SmtpClient("localhost");

            MailMessage memo = new MailMessage();

            memo.IsBodyHtml = true;

            memo.From = new MailAddress("[e-mail]");

            foreach (string emailAddress in emailAddresses)
            {
                memo.To.Add(emailAddress);
            }

            memo.Body = messageBody;
            memo.Subject = messageSubject;

            Attachment attachment = new Attachment(contentStream, "termenLitigiu.ics", "text/calendar");
            attachment.TransferEncoding = System.Net.Mime.TransferEncoding.Base64;
            memo.Attachments.Add(attachment);
            smtp.Send(memo);

这工作和做什么是应该做的，它会发送一个工作vCalendar文件（由Outlook识别）。

This works and does what is supposed to do, it sends a working (recognized by outlook) vcalendar file.

的问题是，在邮件的主体，除了消息体参数的内容，附加文件的内容也会出现，是这样的：

The problem is that in the body of the mail, besides the contents of the messageBody parameter, the contents of the attached file also appear, something like this:

我想摆脱那种文字，并只显示我的消息体参数的内容与刚刚附加到邮件消息vCalendar文件。
我怎样才能做到这一点？这是一个前景问题和编码问题？

I want to get rid of that text, and display only the contents of my messageBody parameter and have the vCalendar file just attached to the mail message. How can i do this? Is this an outlook issue or a coding issue?

编辑：我只是在显示Microsoft Outlook中的邮件感兴趣。我看着到消息的来源（在Outlook中右键点击>查看源代码），我想摆脱的文字是在＆LT;身体> ＆LT; /体<消息/ code >> html标记）

I'm only interested in displaying the message in Microsoft Outlook. I've looked into the source of the message (in Outlook right click > View Source) and the text i want to get rid of is within the <body></body> html tags of the message)

推荐答案

找到了解决办法：

的http://msdn.microsoft.com/en-us/library/system.net.mime.dispositiontypenames.attachment.aspx

在我更换附件的构造文本/日历与 MediaTypeNames.Application.Octet 并集在 DispositionType 到附件，而不是内联这可能是的默认值。

In the constructor of the Attachment I replaced "text/calendar" with MediaTypeNames.Application.Octet and set the DispositionType to Attachment as opposed to Inline which was probably the default value.

            Attachment attachment = new Attachment(contentStream, "termenLitigiu.ics", MediaTypeNames.Application.Octet);
            attachment.ContentDisposition.DispositionType = DispositionTypeNames.Attachment;

现在让我用含有什么应该的邮件正文和工作的.ics附件干净的邮件。

It now gives me a clean mail message with the body of the message containing what it should and a working .ics attachment.
