MVC 4 从网站向客户端发送邮件

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，以便在代理单击保存时，无论是在编辑还是创建后，都会向客户端发送电子邮件，引用记录。该电子邮件将包含一个记录定位器。客户端电子邮件和记录定位器是每条记录中的项目。

我拿到了表格，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，如果我缺少任何使用语句，请告诉我。任何反馈不胜感激。谢谢！

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`
