example from pro Asp.net book?

Question

I am working on the partyInvities (the first asp.net mvc application) example on Pro Asp.Net book.

When I try to send email to the party organizer I am getting an error saying that the smtp host is not specified. How can I get it right? Here is my code and error.

//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(
             "[email protected]", "[email protected]", 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);
         }

     }


     }

how can i get it right?

In order to be able to send an email you need an SMTP server. If you don't have an SMTP server setup you could for debugging purposes put the following in your web.config:

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

Now all emails will be stored in the c:\emails folder instead of being sent so that you can check if your code works properly.

As far as configuring a real SMTP server this is a question you might ask on Serverfault because it is off-topic for StackOverflow.

I tested it and it is working, you need to create the email folder manually before sending emails. amrelgarhy.com/blog/…

I had this same issue and was able to resolve it. The problem is when you are changing the code in the Web.config and saving it, it is not actually saving it if you still have Web Pages running with the error message as well as possibly other things running within Visual Studio.

So to fix it

Close all web pages.
Close Visual studio
Go back into VS and check the Web.config file. You will notice it doesn't have the mailSettings code in it.
Add the mailSettings code and run it again. It will run fine now.

This just sounds...weird. I have never personally witnessed this behavior.

I had the same issue and tried the solutions here. Nothing worked. I then saw there was a web.config in View folder as well as one in the root folder. Make sure you are modifying the root folder web.config.
