Question

这是我的应用程序，我需要发送电子邮件。它可以正常使用gmail.is有可能对雅虎邮件做同样的事情吗？（如果来自textbox有@gmail.com它必须转到控制器中的smtp.gmail.com步骤，如果从textbox有@yahoo.com它必须转到smtp.mail.yahoo.com - 这是可能的吗？）

我的控制器：

 using emailtest1.Models;
    using System.IO;
    using System.Net;
    using System.Net.Mail;
    using System.Web.Mvc;
    namespace emailtest1.Controllers
    {

        public class HomeController : Controller
        {
            // GET: Home
            public ActionResult Index()
            {
                return View();
            }
            [HttpPost]
            public ActionResult Index(EmailModel model)
            {
                using (MailMessage mm = new MailMessage(model.Email, model.To))
                {
                    mm.Subject = model.Subject;
                    mm.Body = model.Body;
                    if (model.Attachment.ContentLength > 0)
                    {
                        string fileName = Path.GetFileName(model.Attachment.FileName);
                        mm.Attachments.Add(new Attachment(model.Attachment.InputStream, fileName));
                    }
                    mm.IsBodyHtml = false;
                    using (SmtpClient smtp = new SmtpClient())
                    {
                        smtp.Host = "smtp.gmail.com";
                        smtp.Host = "smtp.mail.yahoo.com";
                        smtp.EnableSsl = true;
                        NetworkCredential NetworkCred = new NetworkCredential(model.Email, model.Password);
                        smtp.UseDefaultCredentials = false;
                        smtp.Credentials = NetworkCred;
                        smtp.Port = 587;
                        smtp.Port = 25;
                        smtp.Send(mm);
                        ViewBag.Message = "Email sent.";
                    }
                }
                return View();
            }
        }
    }

我的模特：

using System.Web;
namespace emailtest1.Models
{
        public class EmailModel
        {
            public string To { get; set; }
            public string Subject { get; set; }
            public string Body { get; set; }
            public HttpPostedFileBase Attachment { get; set; }
            public string Email { get; set; }
            public string Password { get; set; }
        }
}

Answer 1

您无法一个接一个地覆盖Host和Port属性。你必须提出一个条件：

if(model.Email.contains("@gmail.com")){
     smtp.Host = "smtp.gmail.com";
     smtp.Port = 587;
} else if(model.Email.contains("@yahoo.fr")) {
     smtp.Host = "smtp.mail.yahoo.com";
     smtp.Port = 587;
}

Answer 2

是的，但不像你做的那样，当你做的时候：

smtp.Host = "smtp.gmail.com";
smtp.Host = "smtp.mail.yahoo.com";

您正在覆盖SMTP。

你能做的就是这个

    smtp.Port = 587;
    if (textbox.value.contains("@gmail.com"))
            smtp.Host = "smtp.gmail.com";
    ELSE (textbox.value.contains("@yahoo.com"))
             smtp.Host = "smtp.mail.yahoo.com";

之后做了工作......

如何使用mvc中的应用程序使用gmail和yahoo发送邮件？
