AppSettingsSection appSettings = (AppSettingsSection)config.GetSection("appSettings");
KeyValueConfigurationCollection keyValues = appSettings.Settings;

Dictionary<string, string> items = new Dictionary<string, string>();
 foreach (string key in keyValues.AllKeys)
{
       items.Add(key, keyValues[key].Value);
