从亲Asp.net书的例子？

Question

我正在研究Pro Asp.Net上的partyInvities（第一个asp.net mvc应用程序）示例。

当我尝试发送电子邮件给派对管理器时，我收到一条错误消息，指出未指定smtp主机。我怎样才能解决它？这是我的代码和错误。

//code guestresponse 

public class GuestResponse 
    { 
    [Required(ErrorMessage="* Please Enter Your Name")] 
    public string Name { get; set; } 

    [Required(ErrorMessage="* Please Enter Your Email Id")] 
    [RegularExpression(".+\\@.+\\...+",ErrorMessage=" * Please Enter Valid Email Id")] 
    public string Email {get; set; } 

    [Required(ErrorMessage = "* Please Enter Your Phone Number")] 
    public string Phone { get; set; } 

    [Required(ErrorMessage = "* Please Specify Whether You Will Attend or Not")] 
    public bool? WillAttend { get; set; } 


    private MailMessage BuildMailMessage() 
    { 
     var message = new StringBuilder(); 

     message.AppendFormat("Date: {0: yyyy-MM-dd hh:mm}\n", DateTime.Now); 
     message.AppendFormat("RSVP from : {0}\n", Name); 
     message.AppendFormat("Email: {0}\n", Email); 
     message.AppendFormat("Phone: {0}\n", Phone); 
     message.AppendFormat("Can Come: {0}\n", WillAttend.Value ? "yes" : "No"); 

     return new MailMessage(
      "rsvps@example.com", "party@example.com", Name + (WillAttend.Value ? "will attend" : "Won't attend"), message.ToString()); //From, To, Subject, Body 
    } 

    public void Submit() 
    { 
     using (var smtpClient= new SmtpClient()) 
     using (var mailMessage = BuildMailMessage()) 
     { 
      smtpClient.Send(mailMessage); 
     } 

    } 


    }

     Enabling request validation in view pages would cause validation to occur

Answer 1

how can i get it right?

为了能够送你需要一个SMTP服务器的电子邮件。如果你没有一个SMTP服务器设置你可以为调试目的放在你的web.config以下：

<system.net> 
    <mailSettings> 
     <smtp deliveryMethod="SpecifiedPickupDirectory"> 
      <specifiedPickupDirectory pickupDirectoryLocation="c:\email"/> 
      <network host="localhost"/> 
     </smtp> 
    </mailSettings> 
</system.net> 

现在，所有的电子邮件将被存储在c:\emails文件夹，而不是发送，这样就可以检查如果你的代码正常工作。

至于配置真正的SMTP服务器，这是一个问题，你可能会问Serverfault，因为它是StackOverflow的主题。

Answer 2

我有这个相同的问题，并能够解决它。问题在于，当您更改Web.config中的代码并将其保存时，如果您仍然有运行Web页面的错误消息以及可能在Visual Studio中运行的其他内容，实际上并未保存它。

因此，要解决这个问题

1. 关闭所有网页。
2. 关闭Visual Studio
3. 回到VS并检查Web.config文件。你会注意到它没有mailSettings代码。
4. 添加mailSettings代码并再次运行。它现在运行良好。

Answer 3

我有同样的问题，并尝试在这里的解决方案。没有工作。然后我看到View文件夹中有一个web.config文件，并且在根文件夹中有一个web.config文件。确保你修改了根文件夹web.config。
