 You can use the following code:  
  Private Zero UpdateConfig (string key, string value, string fileName) {var configFile = ConfigManager.OpenExeConfiguration (fileName); Configfile.AppSettings.Settings [key] .Value = value; ConfigFile.Save (); }   
 Where: file name is the full path + application name (c: \ project \ application.exe)  
 In your case, change the app settings by section Do:  
  configfile.Sections ["nhibernateSettings"]
