The .NET Framework 2.0 provides APIs for accessing settings in a configuration file. Here's how you access the mail settings of a config file programmatically:

C#

using System.Configuration;
using System.Web.Configuration;
using System.Net.Configuration;

Configuration configurationFile = WebConfigurationManager.OpenWebConfiguration("PathToConfigFile");

MailSettingsSectionGroup mailSettings = configurationFile.GetSectionGroup("system.net/mailSettings") as MailSettingsSectionGroup;

if (mailSettings != null)
{
    int port = mailSettings.Smtp.Network.Port;
    string host = mailSettings.Smtp.Network.Host;
    string password = mailSettings.Smtp.Network.Password;
    string username = mailSettings.Smtp.Network.UserName;
}
VB.NET

Imports System.Configuration
Imports System.Web.Configuration
Imports System.Net.Configuration

Dim configurationFile As Configuration = WebConfigurationManager.OpenWebConfiguration("PathToConfigFile")

Dim mailSettings As MailSettingsSectionGroup = configurationFile.GetSectionGroup("system.net/mailSettings")

If Not mailSettings Is Nothing Then
    Dim port As Integer = mailSettings.Smtp.Network.Port
    Dim host As String = mailSettings.Smtp.Network.Host
    Dim password As String = mailSettings.Smtp.Network.Password
    Dim username As String = mailSettings.Smtp.Network.UserName
End If

Sirz,

This is excellent codez. Thank you so much.

I agree, this is an excellent post. Thanks for the info.

Cheers,

Nice how-to, great job, even tough i use vb

Yes gr8 indeed...

Okay, when I do this:

Configuration

configurationFile = WebConfigurationManager.OpenWebConfiguration("Web.config");

The error I got is:

The relative virtual path 'Web.config' is not allowed here.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentException: The relative virtual path 'Web.config' is not allowed here.

Any help is appreciated. 

Try using

configurationFile = WebConfigurationManager.OpenWebConfiguration(HttpContext.Current.Request.ApplicationPath)

 

this will get the path to the applications web.config file.

Thanks! I will give that a try. However, it seems that if I do this:

configurationFile = WebConfigurationManager.OpenWebConfiguration("/web.config")

then it works. So I'm not sure why but it's working now.

As far as I can tell, OpenWebConfiguration() doesn't work when trust level is set to medium, which is what I'm locked into on my Godaddy shared hosting. It gets FileIOPermission errors.

 I'm trying to send mail from and to the address defined in this section of my web.config file:

<

system.net requirePermission="false"> <!-- I've tried it with and without this setting -->

<

mailSettings requirePermission="false">

<

smtp from="who@myhost.com">

<

network host="mail.myhost.net" userName="xxxxx" password="xxxx"/>

</

smtp>

</

mailSettings>

</

system.net>

In addition to OpenWebConfiguration(), I've also tried:

WebConfigurationManager.GetSection("system.net/mailSettings/smtp")  // (Which returns a null object)

I've been researching this for several days, and can't find anything that works under medium trust. The only way I've been able to control the address is to hard code it into my program.

Can anybody shed any light on this problem?  Is there some other way to send email that automatically sets the from or to address to the mailSettings/smtp from   setting?

Actually when you use the SmtpClient class to send your emails, all you need to do is to add following lines to your web.config file.

<system.net>

     <mailSettings>
           <smtp deliveryMethod="Network" from="xxxxx@yyyyy.zzz">
                <network host="smtpout.secureserver.net" userName="mmmm@nnnn.ppp" password="kkkkkkkkkkkk" />
           </smtp>
      </mailSettings>
 </system.net>

You don't need to explicitly retrieve info from your web.confg file.

I am Agree... Good Post

hi..

my problem is that "mail sending function" doesn't work on http://www.vwdhosting.net .. i don't know why!! though it works fine "locally"

 

I  use it to recover password . It works fine "locally" with the following web.config settings: <system.net>

<mailSettings>

<smtp from="myname@gmail.com" deliveryMethod="Network">

<network host="smtp.gmail.com" port="587" userName="myname@gmail.com" password="mypassword"></network>

</smtp>

</mailSettings>

</system.net>
