Protecting Base class object in C#

How 

 public class BaseAppConstants
    {
        public const string StLiveIdCookieName = "XYZ";
    }


public class AppConstants : BaseAppConstants
{


}

How can I make changes so user can not direct access base class they can only use like this AppConstants.StLiveIdCookieName;

You should either

  • A) move the constant to the level at which is it supposed to be used (i.e. declare it in AppConstants and remove it from BaseAppConstants) or,

  • B) use a different modifier to make it inaccessible and provide an accessor in the other class (i.e. use protected in BaseAppConstants and reimplement in AppConstants with something like public const string StLiveIdCookieName = BaseAppConstants.StLiveIdCookieName - but this kind of defies the usage of constants).

If you set the property in the base class to protected it will only be usable in derived classes.

public class BaseAppConstants
{
    protected const string StLiveIdCookieName = "XYZ";
}
