namespace doctor_inheritance
{
    class nurse:doctor
    {
        private void ret()
        {
            Console.WriteLine("hello");
            records();
        }
    }
    class doctor
    {
        //this is the secret message applied only to the doctors
        int name, specialization;
        private void records()
        {
            Console.WriteLine("these are the records maintained by doctors which cannot be accessed by others");
        }
    }
    class patient:doctor
    {
       public void patients()
        {
          //  doctor d = new doctor();
            records();
            Console.WriteLine("PATIENTS ");
        }
    }
    class Program
    {
        static void Main(string[] args)
        {
            patient p = new patient();
              doctor d = new doctor();
            d.records();
            // p.records();
            p.patients();
            Console.ReadLine();
    }

    }
}

在此部分代码中，我为医生做了单独的课程，病人可以访问医生的信息，但是当我尝试编译代码时，如果显示错误，则病人无法访问医生的信息，请帮助我解决错误
