My take on JJS's reply: Config file:

Code to retrieve into string[]

 private void button1_Click(object sender, EventArgs e)
    {

        string[] output = CollectFromConfig("List1");
        foreach (string key in output) label1.Text += key + Environment.NewLine;
        label1.Text += Environment.NewLine;
        output = CollectFromConfig("List2");
        foreach (string key in output) label1.Text += key + Environment.NewLine;
    }
    private string[] CollectFromConfig(string key)
    {
        NameValueCollection keyCollection = (NameValueCollection)ConfigurationManager.GetSection(key);
        return keyCollection.AllKeys;
    }

IMO, that's as simple as it is going to get. Feel free to prove me wrong :)
