HOW TO: Accessing Config File Programmatically

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 such as example…

C#

using System.Configuration;

using System.Web.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
