Imar:
This is probably a "no brainer" for you. I'm new to .NET and C# and see the following error on my browser for your Email Demo :

The specified string is not in the form required for an e-mail address.

Source Error:


Line 18: protected void Page_Load(object sender, EventArgs e)Line 19: {Line 20: MailMessage myMessage = new MailMessage();Line 21: myMessage.Subject = "Greetings";Line 22: myMessage.Body = "Hello world, from Planet Wrox";

Source File: c:\BegASPNET\Site\Demos\Email.aspx.cs Line: 20

I have used your downloaded code for this book to verify the code and the webconfig file.


The complete code for the Email.aspx.cs file on my XP computer using VWD is listed below:

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Net.Mail;
publicpartialclassEmail : BasePage
{
protectedvoid Page_Load(object sender, EventArgs e)
{
MailMessage myMessage = newMailMessage();
myMessage.Subject = "Greetings";
myMessage.Body = "Hello world, from Planet Wrox";
myMessage.From = newMailAddress("[email protected]", "myname");
myMessage.To.Add(newMailAddress("[email protected]", "myname"));
SmtpClient mySmtpClient = newSmtpClient();
mySmtpClient.Send(myMessage);
}
}

My code for the Email.aspx under the Demos folder is listed below:

<%@PageLanguage="C#"Debug="true"MasterPageFile="~/MasterPages/MasterPage.master"AutoEventWireup="true"CodeFile="Email.aspx.cs"Inherits="Email"Title="E-mail Demo" %>
<asp:ContentID="Content1"ContentPlaceHolderID="head"Runat="Server">
</asp:Content>
<asp:ContentID="Content2"ContentPlaceHolderID="cpMainContent"Runat="Server">
</asp:Content>

All feedback is appreciated.

Hi there,

Is this the actual code you're executing? Or did you modify the addresses before you posted here? The current addresses seem fine to me, so those shouldn't be a problem. The error you get is typically thrown when you enter an invalid To or From address, like "you" instead of [email protected].

And how does your <system.net /> element in web.config look?

Imar:
Thank you for your quick response.
To answer your questions from your email to me:

Is this the actual code you're executing? No

Or did you modify the addresses before you posted here? Modified the addresses.
From my email.aspx file:

public partial class Email : BasePage
{
protected void Page_Load(object sender, EventArgs e)
{
MailMessage myMessage = new MailMessage();
myMessage.Subject = "Greetings";
myMessage.Body = "Hello world, from Planet Wrox";

myMessage.From = new MailAddress("[email protected]", "Gay");
myMessage.To.Add(new MailAddress("[email protected]", "Gay Farace-Mann"));

SmtpClient mySmtpClient = new SmtpClient();
mySmtpClient.EnableSsl = false;
mySmtpClient.Send(myMessage);
}
}
The current addresses seem fine to me, so those shouldn't be a problem. The error you get is typically thrown when you enter an invalid To or From address, like "you" instead of [email protected].

And how does your <system.net /> element in web.config look?
<system.net>
<mailSettings>
<smtp deliveryMethod="Network" from="gay-faracemann&lt;@cox.net&gt;">
<network host="smtp.west.cox.net" userName="gay-faracemann" password="Boysare2!"/>
</smtp>
</mailSettings>
</system.net>
