Question

在发送包含阿拉伯字符（显示为????）的附件文件时出现问题用于文件名。但是，如果文件名是英语，则不会出现此问题。我尝试使用UTF-8来回编码，但无法正常工作。

    private static void GenerateAndSendMail(string subject, string body, List<string> filesFullPath = null)
    {
        try
        {
            var mailMessage = new MailMessage();
            mailMessage.From = new MailAddress(MyAppConfigService.CurrentUser.Email);
            mailMessage.Subject = subject;
            mailMessage.IsBodyHtml = true;
            mailMessage.Body = body;
            mailMessage.SubjectEncoding = Encoding.Unicode;
            mailMessage.HeadersEncoding = Encoding.Unicode;
            mailMessage.BodyEncoding = Encoding.Unicode;

            if (filesFullPath != null && filesFullPath.Count > 0)
            {
                foreach (var item in filesFullPath)
                {
                    var Attachment = new Attachment(item);
                    Attachment.NameEncoding = Encoding.Unicode;
                    mailMessage.Attachments.Add(Attachment);
                }
            }
            //save the MailMessage to the filesystem
            var filename = Path.GetTempPath() + "mymessage.eml";
            mailMessage.Save(filename);
            //Open the file with the default associated application registered on the local machine
            Process.Start(filename);
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }

经过6个小时的互联网研究，并尝试使用不同类型的编码（例如UTF-8，UTF-16和Unicode），我找到了解决方案。

问题出在附件编码中，无法正确编码阿拉伯字符，并且编码结果错误。解决方案是在NameEncoding下添加以下行代码：

 Attachment.ContentType.CharSet = "UTF-8";

C＃附件和MailMessage阿拉伯字符
