如何使用mvc中的應用程序同時使用Gmail和雅虎發送郵件？

這是我的應用程序，我需要發送電子郵件。它與gmail.is工作正常，可以用yahoo郵箱做同樣的事情嗎？（如果從文本框有@ gmail.com它必須去控制器中的smtp.gmail.com步驟，如果從文本框有@ yahoo.com它必須去smtp.mail.yahoo.com - 它是可能的？）如何使用mvc中的應用程序同時使用Gmail和雅虎發送郵件？

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(); 
      } 
     } 
    }

我的模型：

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; } 
     } 
}

    Layout = null;

爲了澄清，是與雅虎發送電子郵件的問題，或者是問題「我該怎麼辦兩「？如果是這樣，你是否爲你寫的語句嘗試了一個if/else條件？（'如果從文本框有@ gmail.com它必須去控制器中的smtp.gmail.com步驟，如果從文本框有@ yahoo.com它必須去smtp.mail.yahoo.com'）？ –

@ashwanth你能解決這個話題嗎？ – GGO

是的，我得到了解決方案@GGO謝謝 – ashwanth

不能一個接一個地重寫Host和Port屬性。你必須把一個條件：

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; 
}

是的，但不喜歡你做的方式，當你做：

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

你覆蓋SMTP。

你可以做的就是這個

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";

該做的工作後...
