所以我有一个数据库程序，MVC4，C#，发布到 Azure。

代理将在数据库中创建记录，然后客户端将查看它们。记录只能由代理创建或编辑。

我遇到的问题是邮件功能。我想要一个功能，当代理点击保存时，无论是在编辑还是创建之后，都会向客户端发送一封电子邮件，引用记录。该电子邮件将包含一个记录定位器。客户电子邮件和记录定位器是每条记录中的项目。

我把表格弄好了，但是控制器和 System.Main.Net 有问题。我的编辑控制器代码如下。

using System;
using System.Collections.Generic;
using System.Data;
using System.Data.Entity;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using TrepPortal.Models;
using System.Net.Mail;

    //
    // GET: /AgntActions/Edit/5

    public ActionResult Edit(int id = 0)
    {
        ClientActions clientactions = db.ClientActions.Find(id);
        if (clientactions == null)
        {
            return HttpNotFound();
        }
        return View(clientactions);
    }

    //
    // POST: /AgntActions/Edit/5


    [HttpPost]
    public ActionResult Edit(ClientActions clientactions)
    {
        if (ModelState.IsValid)
        {
            db.Entry(clientactions).State = EntityState.Modified;
            db.SaveChanges();

            //mail function
            MailMessage message = new MailMessage();
            message.From = new MailAddress("nick@cooktravel.net");
            //message.To.Add(new MailAddress("nick@cooktravel.net"));
            message.To.Add(clientactions.ClientEmail);
            message.Subject = "This is my subject";
            message.Body = "Your Cook Travel reservation has been updated. The record locator is "clientactions.SabreLocator" . Please visit cooktravelportal.net to view it.";

            //SmtpClient client = new SmtpClient("smtp.cooktravel.net, 495");//old
            SmtpClient client = new SmtpClient("smtp.cooktravel.net", 25);//

            client.UseDefaultCredentials = false;
            client.EnableSsl = false;
            client.Credentials = new System.Net.NetworkCredential("nick@cooktravel.net", "Password");
            client.DeliveryMethod = SmtpDeliveryMethod.Network;

            client.Send(message); //on debug, error comes here as SmtpException unhandled

            return RedirectToAction("Index");
        }
        return View(clientactions);
    }

现在我没有很多经验。我通过阅读许多文章和示例将其放在一起。另外，如果我遗漏了任何 using 语句，请告诉我。任何反馈表示赞赏。谢谢！

也许你需要修改这行代码：

SmtpClient client = new SmtpClient("smtp.cooktravel.net, 495");

到

SmtpClient client = new SmtpClient("smtp.cooktravel.net",495);

您可以尝试更改：

  SmtpClient client = new SmtpClient("smtp.cooktravel.net, 495");

到：

SmtpClient client = new SmtpClient("smtp.cooktravel.net");
client.Port = 495;

或者您可以显示使用异常详细信息吗？

Code (Model)




I am trying to send an email inside an action. However, the action always returns a blank screen.

View:

<% using(Html.BeginForm("Sendlink", "Home")) %>
    <% { %>
     <input type="text" id="toemail" value="" />
        <input type="submit" value="Send" />
    <% } %>

Controller:

public ActionResult Sendlink()
{
    return View();
}

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Sendlink(FormCollection formCollection)
{
    try
    {
        string message = Session["link"].ToString();
        string toemail = formCollection["toemail"];
        MailEngine.Send("mail@mail.com", toemail, "link", message);
        return RedirectToAction("CanvasShare");
    }
    catch
    {

    }
    return null;
}

Class MailEngine:

public static void Send(string from, string to, string subject, string body)
{
    try
    {
        MailMessage mail = new MailMessage(from, to, subject, body);
        SmtpClient client = new SmtpClient("smtp.mymail.com");
        client.DeliveryMethod = SmtpDeliveryMethod.Network;
        client.EnableSsl = false;
        client.Send(mail);
    }
    catch
    {

    }
}`enter code here`

System.Net.Mail 仅正确支持本地主机上的 25 端口，我花了很多时间才找到一篇对这个问题有完整解释的文章。

也许它会帮助你：

            string from = "";
            string fromPass = "";

            MailMessage eMail = new MailMessage();
            eMail.IsBodyHtml = true;
            eMail.Body = message;
            eMail.From = new MailAddress(from);
            eMail.To.Add(address);
            eMail.Subject = subject;
            SmtpClient SMTP = new SmtpClient();

            SMTP.Credentials = new NetworkCredential(from, fromPass);
            SMTP.Host = "localhost";
            SMTP.Send(eMail);

编辑：如果您需要使用 465 或其他端口，您需要使用单独的库

@Jayraj

显然，您的 try 块中有一些错误。它捕获了错误，但你没有在那里做任何事情。我怀疑这是您的 Session["link"] 为空。在 ActionResult 中返回 null 将导致空白屏幕。
