      {
       Configuration configFile = null;

        configFile = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
        ConnectionStringsSection configSection = configFile.GetSection("connectionStrings") as ConnectionStringsSection;
        if ((!(configSection.ElementInformation.IsLocked)) && (!(configSection.SectionInformation.IsLocked)))
        {
         if (encrypt && !configSection.SectionInformation.IsProtected)
         //encrypt is false to unencrypt
         {
          configSection.SectionInformation.ProtectSection("DataProtectionConfigurationProvider");
         }
         if (!encrypt && configSection.SectionInformation.IsProtected)
         //encrypt is true so encrypt
         {
          configSection.SectionInformation.UnprotectSection();
         }
         //re-save the configuration file section
         configSection.SectionInformation.ForceSave = true;
         // Save the current configuration.
         configFile.Save();
        }
