Question

我正在创建一个电子邮件表单，此表单正在运行。现在我想为主题字段添加选项。如果主题取消，则应在消息（正文）字段中显示取消消息，例如您的服务已取消。如果主题是欢迎，那么它应该在消息（正文）字段中显示欢迎来到我们的团队消息。

<div class="container" style="background-color:powderblue; position:center">
    <form method="post" action="Form" style="background-color:powderblue; color:indianred">
        <span class="form-control-static" style="color:black"><h1>Email Form</h1></span>      

        <br />

        <span class="form-control-static">Receiver Email:</span>
        <input class="form-control" type="text" name="receiverEmail" />
        <span class="form-control-static"> Subject:</span>
        <select name="SelectSubject"   value="Select Subject" id="ViewBy" class=" form-control">
            <option name="cancel"      value="Cancel">Cancel</option>
            <option name="welcome"     value="Welcome">Welcome</option>
        </select>
        <span class="form-control-static">Message</span>
        <textarea class="form-control" cols="8" rows="9" name="message"></textarea>

        <br />
        <br />

        <button class="btn btn-primary" type="submit">Send Email</button>    
    </form>
</div class="container">

这是我的电子邮件表单代码

    [HttpPost]

    public ActionResult Form(string receiverEmail, string subject,  string message)
    {
        try
        {
            if (ModelState.IsValid)
            {
                var senderemail = new MailAddress("test57697@gmail.com","Test Email");
                var receiveremail = new MailAddress(receiverEmail, "Receiver");
                var password = "Test111222";

                //From view
                var sub = subject;
                var body = message;
                //var sub = subject;
                //var body = message;



                var smtp = new SmtpClient
                {
                    Host = "smtp.gmail.com",
                    Port = 587,
                    EnableSsl = true,
                    DeliveryMethod = SmtpDeliveryMethod.Network,
                    UseDefaultCredentials = false,
                    Credentials = new NetworkCredential(senderemail.Address,password)
                };

                using (var mess = new MailMessage(senderemail, receiveremail)
                {
                    Subject = sub,
                    Body = body

            })

                {
                    smtp.Send(mess);

                }
                Response.Write("Message sent successfully!");
                return View();

            }

        }
        catch (Exception)
        {
            ViewBag.Error = "Couldn't send email.";
        }
        return View();
    }
}

}

嗨！我现在有另一个问题。我使用gmail服务器发送电子邮件，但现在我想使用 django服务器，C＃而不是gmail。有什么建议吗？

Answer 1

根据我的理解，你在这里编写的代码是不合适的，但是根据我的理解，它们会为你的场景提供一个解决方案。

//来自视图

var sub = subject;
if(sub.ToLower()=="cancel")
{
 var body= "your service is cancelled";
}
else
{
var body= "Welcome Message";
}

谢谢Rajesh。这是正确的答案而且有效。我刚刚删除了最后一行。

                var sub = subject;
                var body = message;

                if (sub.ToLower() == "cancel")
                {
                     body = "your service is cancelled";
                }
                else
                {
                    body = "Welcome Message";
                }
