Is this encapsulation? read only?

        class TestEncaps

        {

            private List<string> s;

         

            public TestEncaps()

            {

                s = new List<string>();

                s.Add("blah");

            }

            public void print()

            {

                Console.WriteLine(s[0]); 

            }

            public List<string> S

            {

                get { return s; }

            }

        }

       

        static void Main(string[] args)

        {

            TestEncaps te = new TestEncaps();

            te.S[0]= "blah!";

            te.print(); 

p.s.

this is not a solution

            public List<string> S

            {

                get {

                    string[] s2 = new string[s.Count];

                    s.CopyTo(s2);

                    return s2.ToList();

                }

            }

because CopyTo makes a shallow copy
