Update Web.config + Asp.net VB.net

Ever needed to update the web.config dynamically?

Make sure you add a reference at the top of the page to

Imports System.Web.Configuration

  Dim value As String = "mskilton@gmail.com"

        Dim config As Configuration = 
 webConfigurationManager.OpenWebConfiguration("~")
        Dim appsetting As AppSettingsSection = 
  config.GetSection("appSettings")

        appsetting.Settings("emailaddress").Value = value

        config.Save()

Have fun updating your web.config programmatically!
