K works..

  // type parameter T in angle brackets
    public class GenericList<T>
    {
        // The nested class is also generic on T
        private class Node
        {

            {
                next = null;

            }

            // T as private member data type
            private T data;

            // T as return type of property
            public T Data
            {
                get { return data; }
                set { data = value; }
            }

            private Node next;
            public Node Next
            {
                get { return next; }
                set { next = value; }
            }
        }

        private Node head;

        // constructor
        public GenericList()
        {
            head = null;
        }

        // T as method parameter type:
        public void AddHead(T t)
        {
            Node n = new Node(t);
            n.Next = head;
            head = n;
        }

        /// <summary>
        /// foreach 문을 사용하기 위해 GetEnumerator 정의

            while (current != null)
            {

                current = current.Next;
            }
        }
    }

    class Program

            for (int x = 0; x < 10; x++)
