每次用户创建新评论时，我都会尝试发送电子邮件。我已经安装了 Postal.MVC5 包

评论模型

public int Id { get; set; }

    [Required]
    [MinLength(3)]
    [MaxLength(20)]
    public string Asunto { get; set; }
    [Required]
    public string Detalle { get; set; }
    [DataType(DataType.Date)]
    public DateTime Fecha { get; set; }
    [DataType(DataType.Time)]
    public DateTime Hora { get; set; }
    public  virtual Local local { get; set; }
    public virtual string username { get; set; }

新评论电子邮件模型

public class NewCommentEmail : Email
{
    public string To { get; set; }
    public string UserName { get; set; }
    public string Comment { get; set; }
}

控制器

 [HttpPost]
    public ActionResult AgregarComentario(NotasAdjuntas nota)
    {
        try
        {
            var localId = int.Parse(Request["LocalID"]);
            nota.username = Session["Username"].ToString();

            using (var db = new AutoContex())
            {
                nota.local = db.Locales.Find(localId);
                db.Entry(nota.local).Reference(p => p.Proveedor).Load();
                db.Notas.Add(nota);
                db.SaveChanges();
            }

            var email = new NewCommentEmail();
            email.To = "emilia.lasaga@pedidosya.com";
            email.UserName = nota.username;
            email.Comment = nota.Asunto;               
            email.Send();
            return RedirectToAction("Details", new { @id = localId });                
        }
        catch
        {
            return View();
        }
    }

我也将此添加到 webconfig

<system.net>
<mailSettings>
  <smtp deliveryMethod="SpecifiedPickupDirectory">
    <specifiedPickupDirectory pickupDirectoryLocation="C:\Temp\" />
  </smtp>
</mailSettings>

我得到的错误是：Microsoft.CSharp.RuntimeBinder.RuntimeBinderException:Couldn‌​'t make connection on time of execution in a NULL reference

收到错误的行是：

@Html.ValidationSummary(true, "", new { @class = "text-danger" })

看法

@using (Html.BeginForm()) 
{
@Html.AntiForgeryToken()

<div class="form-horizontal">
    <h4>Notas Adjuntas</h4>
    <hr />
    @Html.ValidationSummary(true, "", new { @class = "text-danger" })

    <div>

我能够通过 smtps 发送电子邮件

这不是我正在寻找的第一种方法（我想通过 Postal.MVC5 来实现）

我所做的是这样的：

创建电子邮件的新类

    using System.Net.Mail;
using System.Net;

namespace AutoPlanMCV.Models
{
    public class NewCommentEmail 
    {
        public static string GmailUsername { get; set; }
        public static string GmailPassword { get; set; }
        public static string GmailHost { get; set; }
        public static int GmailPort { get; set; }
        public static bool GmailSSL { get; set; }

        public string ToEmail { get; set; }
        public string Subject { get; set; }
        public string Body { get; set; }
        public bool IsHtml { get; set; }

        static NewCommentEmail()
        {
            GmailHost = "smtp.gmail.com";
            GmailPort = 25; // Gmail can use ports 25, 465 & 587; but must be 25 for medium trust environment.
            GmailSSL = true;
        }

        public void Send()
        {
            SmtpClient smtp = new SmtpClient();
            smtp.Host = GmailHost;
            smtp.Port = GmailPort;
            smtp.EnableSsl = GmailSSL;
            smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
            smtp.UseDefaultCredentials = false;
            smtp.Credentials = new NetworkCredential(GmailUsername, GmailPassword);

            using (var message = new MailMessage(GmailUsername, ToEmail))
            {
                message.Subject = Subject;
                message.Body = Body;
                message.IsBodyHtml = IsHtml;
                smtp.Send(message);
            }
        }

}

控制器

public ActionResult AgregarComentario(NotasAdjuntas nota)
    {

        try
        {

            var localId = int.Parse(Request["LocalID"]);
            nota.username = Session["Username"].ToString();

            using (var db = new AutoContex())
            {
                nota.local = db.Locales.Find(localId);
                db.Entry(nota.local).Reference(p => p.Proveedor).Load();
                db.Notas.Add(nota);
                db.SaveChanges();

                if (nota.Asunto.Contains("capa"))
                {
                    NewCommentEmail.GmailUsername = "youremail@gmail.com";
                    NewCommentEmail.GmailPassword = "yourpassword";

                    NewCommentEmail mailer = new NewCommentEmail();
                    mailer.ToEmail = "Emailto@gmail.com";
                    mailer.Subject = nota.Asunto;
                    mailer.Body = nota.local.NuevoId + " --  --" + nota.local.NombreComercio + "<br />" + nota.Detalle + "<br /> Hora:" + nota.Hora;
                    mailer.IsHtml = true;
                    mailer.Send();
                }
            }

            return RedirectToAction("Details", new { @id = localId });

        }
        catch
        {
            return View();
        }

    }

我删除了 webconfig 中的内容，并且没有编辑我的视图。之后我没有收到任何错误
