如何从 MVC 5 应用程序发送电子邮件

Question

我有一个客户需要填写的表格。提交表单后，我想将表单索引视图中的基本信息（名字、姓氏、电话号码等）发送到电子邮件。我目前正在使用 GoDaddy 作为我的托管站点。这有关系吗，或者我可以直接从我的 MVC 应用程序发送电子邮件吗？我的模型、视图、控制器有以下内容。我以前从来没有这样做过，我真的不知道该怎么做。

型号：

public class Application
{
    public int Id { get; set; }

    [DisplayName("Marital Status")]
    public bool? MaritalStatus { get; set; }


    [Required]
    [DisplayName("First Name")]
    public string FirstName { get; set; }

    [DisplayName("Middle Initial")]
    public string MiddleInitial { get; set; }
     [Required]
    [DisplayName("Last Name")]
    public string LastName { get; set; }
}

控制器：

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

// POST: Applications/Create
// To protect from overposting attacks, please enable the specific properties you want to bind to, for 
// more details see http://go.microsoft.com/fwlink/?LinkId=317598.
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Index([Bind(Include = "Id,FirstName,MiddleInitial,LastName")] Application application)
{
    ViewBag.SubmitDate = DateTime.Now;

    if (ModelState.IsValid)
    {
        application.GetDate = DateTime.Now;
        db.Applications.Add(application);
        db.SaveChanges();
        return RedirectToAction("Thanks");
    }

    return View(application);
}

<table class="table table-striped">
    <tr>
        <th>
           @Html.ActionLink("First Name", "Index", new { sortOrder = ViewBag.NameSortParm })
        </th>

        <th>
            @Html.ActionLink("Last Name", "Index", new { sortOrder = ViewBag.NameSortParm })
        </th>

        <th>
            @Html.ActionLink("Date Submitted", "Index", new { sortOrder = ViewBag.NameSortParm})
        </th>
    </tr>

@foreach (var item in Model) {
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.FirstName)
        </td>

        <td>
            @Html.DisplayFor(modelItem => item.LastName)
        </td>

        <td>
            @Html.DisplayFor(modelItem => item.GetDate)
        </td>
    </tr>
}

Answer 1

您需要一个 SMTP 服务器来发送电子邮件。不知道 GoDaddy 是如何工作的，但我相信他们会提供一些东西。

要从 MVC 应用程序发送电子邮件，您可以在代码或 web.config 中指定 SMTP 详细信息。我建议在配置文件中，因为这意味着它更容易更改。使用 web.config 中的所有内容：

SmtpClient client=new SmtpClient();

否则，在代码中执行：

SmtpClient client=new SmtpClient("some.server.com");
//If you need to authenticate
client.Credentials=new NetworkCredential("username", "password");

现在你创建你的消息：

MailMessage mailMessage = new MailMessage();
mailMessage.From = "someone@somewhere.com";
mailMessage.To.Add("someone.else@somewhere-else.com");
mailMessage.Subject = "Hello There";
mailMessage.Body = "Hello my friend!";

终于发了：

client.Send(mailMessage);

web.config 设置示例：

<system.net>
    <mailSettings>
        <smtp>
            <network host="your.smtp.server.com" port="25" />
        </smtp>
     </mailSettings>
</system.net>

// This example uses SendGrid SMTP via Microsoft Azure
