C#之索引器

实际中不使用这个东西，只做了解

using System.Threading.Tasks;

namespace 索引器 {
    class Program {
        static void Main(string[] args) {
            person p = new person();
            p[] = ;
            p[] = ;
            p[] = ;
            p[] = ;
            p[] = ;
            foreach(var item in p.Numbers) {
                Console.WriteLine(item);
            }
            p[""] = "";
            p[""] = "";
            p[""] = "";
            p[""] = "";
            p[""] = "";
            Console.WriteLine(p[""]);
            Console.ReadLine();
        }
    }
    class person {

        private int[] _numbers = new int[];
        public int[] Numbers {
            get { return _numbers; }
            set { _numbers = value; }
        }
        //索引器，让对象以索引的方式操作数组
        public int this[int index] {
            get { return _numbers[index]; }
            set { _numbers[index] = value; }
        }

        Dictionary<string, string> dic = new Dictionary<string, string>();
        public string this[string index] {
            set { dic[index] = value; }
            get { return dic[index]; }
        }
    }
