c# - asp.net mvc 4 来自站点编码的字母

Question

我的 mvc 网站上有反馈表，我需要将此表发送到电子邮件。
我想测试我的表单，因此我将 MailMessage 对象作为 *.eml 文件保存到磁盘

[HttpGet]
public ActionResult Contacts()
{
    FeedbackForm temp = new FeedbackForm();
    temp.Message = @Resources.Global.Contacts_Form_Message_Field;
    return View(temp);
}

[HttpPost]
public ActionResult Contacts(FeedbackForm Model)
{    
    MailMessage msg = new MailMessage();
    msg.BodyEncoding = Encoding.UTF8;            
    msg.From = new MailAddress(Model.Email,
                              @Resources.Global.Contacts_Form_Email_Title);
    msg.To.Add("<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="3246534b5c531f535c5b4653725f535b5e1c4047" rel="noreferrer noopener nofollow">[email protected]</a>");

    string message = @Resources.Global.Contacts_Form_Name_Field + ": "
                     + Model.Name + "\n"
                     + "Email: " + Model.Email + "\n"
                     + @Resources.Global.Contacts_Form_Phone_Field + ": "
                     + Model.Phone + "\n\n"
                     + Model.Message;
    msg.Body = message;
    msg.IsBodyHtml = false;          

    SmtpClient client = new SmtpClient("mysmtphost");
    client.DeliveryMethod = SmtpDeliveryMethod.SpecifiedPickupDirectory;
    client.PickupDirectoryLocation = @"C:\test";

    try
    {
        client.Send(msg);
    }
    catch (Exception ex)
    {
    }

    FeedbackForm tempForm = new FeedbackForm();
    tempForm.Message = @Resources.Global.Contacts_Form_Message_Field;

    return View(tempForm);
}

我得到:

 X-Sender: "Letter from site" <<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="64171717171717172409050d084a1611" rel="noreferrer noopener nofollow">[email protected]</a>>

为什么信的正文看起来是这样的？

我将从网站用英语和俄语发送信件，并设置 msg.BodyEncoding = Encoding.UTF8;。

我应该怎么做才能不出现编码问题？

Answer 1

您看到的是一条用 Base-64 编码的消息。您可以从电子邮件标题中看到这一点:

Content-Transfer-Encoding: base64

据推测，您正在纯文本编辑器中打开邮件，因此电子邮件内容不会被解码。

如果您使用 Base64 Decoder 解码消息(任何电子邮件客户端都会自动执行此操作)，您会得到以下结果:
