c#-基础-数组使用方式1

1、灵活扩展使用，添加、取出

static void Main(string[] args)
        {

            Su();
            
            Console.ReadKey(true);
            Console.WriteLine("main");
        }
        public static void  Su() {
            string[] li_1 = new string[5];
            li_1[0] = "123456";
            li_1[1] = "name";
            Console.WriteLine(li_1[0].ToString());
            Console.WriteLine(li_1[1].ToString());
            Console.WriteLine("su");

        }
