Chapter 9 p. 310

I'm still trying to get e-mail to go through using the Demo Email.aspx webform following steps 1-5 of the Try It Out in Chapter 9 at pages 309-310.

When I request Email.aspx in my browser (Internet Explorer 8) I receive this error message:

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS0029: Cannot implicitly convert type 'System.Net.Mail.MailMessage' to 'System.Net.Mail.MailAddress'

Source Error:

Line 22: myMessage.Body = "Hello World, from Planet Wrox";
Line 23:
Line 24: myMessage.From = new MailMessage("[email protected]", "myName");
Line 25: myMessage.To.Add(new MailAddress("[email protected]", "myName"));
Line 26:
Source File: c:\BegASPNET\Site\Demos\Email.aspx.cs Line: 24

================================================== =======
The code in Email.aspx is:

<%@ Page Language="C#" MasterPageFile="~/MasterPages/MasterPage.master" AutoEventWireup="true" CodeFile="Email.aspx.cs" Inherits="Email" Title="E-mail Demo" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="cpMainContent" Runat="Server">
</asp:Content>
================================================== ==============
The code in Email.aspx.cs is
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.Net.Mail;

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

myMessage.From = new MailMessage("[email protected]", "My Name");
myMessage.To.Add(new MailAddress("[email protected]", "My Name"));

SmtpClient mySmtpClient = new SmtpClient();
mySmtpClient.Send(myMessage);

}
}
================================================== ================
My web.config settings are:
<system.net>
<mailSettings>
<smtp deliveryMethod="Network" from="My Name <[email protected]>">
<network host="smtp.ISP.net" userName="[email protected]" password="mypassword" />
</smtp>
</mailSettings>
</system.net>
================================================== ========

The email addresses I am using are the same as the one I use with Outlook 2007 through the same smtp settings as I use in Outlook 2007. I have been through Chapter 9 so many times I'm almost sick from doing so. I have checked and rechecked multiple times.

I would sure appreciate some assistance in fixing this problem. Thanks for any clue anyone can provide.

Hi Featheriver,

Take a look at this:

myMessage.From = new MailMessage("[email protected]", "My Name");
myMessage.To.Add(new MailAddress("[email protected]", "My Name"));

You're constructing a MailMessage instead of a MailAddress. Simply change MailMessage to MailAddress:

myMessage.From = new MailAddress("[email protected]", "My Name");
myMessage.To.Add(new MailAddress("[email protected]", "My Name"));

Hope this helps,

Imar

Imar, don't know what I'd do without you. You neatly zeroed in where my error lay. You know, I've truly been through that Email.aspx section of Chapter 9 perhaps a dozen times and never saw that MailMessage vs MailAddress error.

Funny how one can look at something and not see it. Guess it is my age. I'm 76 years old and losing it.

Thank you so much. I made the change you pointed out and--voila!--the mail came through just as it should.

Thank you very very much!

Don't worry about it; it's not an age thing. I can have code like this staring me in the face as well ;-)

A second set of eyes is always very useful...
