How do I divide this function of a linked list for 2 functions One to put data and one to print them???

Question

using system;
using system.collections.generic;

class Program
{
        static void Main()
        {
                LinkedList<string> linked = new LinkedList<string>();

                linked.AddFirst("111");
                linked.AddFirst("222");

                foreach (var item in linked)
                {
                        console.writeLine(item);
                }
        }
}
