reading web.config in Visual Studio 2005

[dcp12345678]

The code below is directly from Microsoft's help. It describes how to
read a value from the Web.config file. I tried out this code and it
does not appear to work (at least when I try it).

If my web.config file I have the following:
<appSettings>
<add key="WebServer" value="localhost"/>
</appSettings>

I want to read out the WebServer value and I used Microsoft's code
below. But again, it doesn't work. However, just doing
AppSettings.Item("WebServer") did the trick. I have no idea why
Microsoft's code below doesn't work. Anybody want to try and explain?

Dim rootWebConfig1 As System.Configuration.Configuration
rootWebConfig1 =
System.Web.Configuration.WebConfigurationManager.O penWebConfiguration(Nothing)
If (0 < rootWebConfig1.AppSettings.Settings.Count) Then
Dim customSetting As
System.Configuration.KeyValueConfigurationElement
customSetting =
rootWebConfig1.AppSettings.Settings("customsetting 1")
If Not (Nothing = customSetting.Value) Then
Console.WriteLine("customsetting1 application string = {0}",
customSetting.Value)
Else
Console.WriteLine("No customsetting1 application string")
End If
End If
