 class Program
    {
        static void Main(string[] args)
        {
            Person p = new Person();
            Console.WriteLine(p.Name);
            var a = p.GetType().GetField("_name", 
                BindingFlags.Instance | BindingFlags.GetField | BindingFlags.NonPublic | BindingFlags.ExactBinding);
            a.SetValue(p, "ghy");
            Console.WriteLine(p.Name);
        }
    }

    public class Person
    {
        private string _name = "Henley";
