C#兩個實體資料互相轉換

1：建構實體，（注意：屬性數量一樣）
    public class C1
    {
        public string age { get; set; }
        public string name { get; set; }
    }
    public class C2
    {
        public string 年齡 { get; set; }
        public string 姓名 { get; set; }
    }

2：填充資料：
            var list = new List<C1>();
            list.Add(new C1
            {
                age = "11",
                name = "admin"
            });
            list.Add(new C1
            {
                age = "22",
                name = "張三"
            });
3：方法調用：  var newlist = ConvertToNewModel<C1, C2>(list);
4：方法：
       public static List<T2> ConvertToNewModel<T1, T2>(List<T1> list)
        {
            var t2 = new List<T2>();
            foreach (var item in list)
            {
                T2 model = default(T2);
                model = Activator.CreateInstance<T2>();

                PropertyInfo[] pi1 = typeof(T1).GetProperties();
                PropertyInfo[] propertys = model.GetType().GetProperties();
                for (int i = 0; i < propertys.Count(); i++)
                {
                    propertys[i].SetValue(model, pi1[i].GetValue(item, null), null);
                }
                t2.Add(model);
            }
            return t2;
        }
