Encrypt Connection String in App.Config (Winforms application)

I had to do this today in .NET 2.0. (Visual Studio 2005)  Found an example on David Hayden’s blog:

Configuration config = ConfigurationManager.
   OpenExeConfiguration(ConfigurationUserLevel.None);

ConfigurationSection section =
    config.GetSection(“connectionStrings“);

if (section != null)

{

    if (!section.IsReadOnly())

    {

        section.SectionInformation.ProtectSection
             (“RsaProtectedConfigurationProvider“);

        section.SectionInformation.ForceSave = true;

        config.Save(ConfigurationSaveMode.Full);

    }

}
