基础知识系列☞C#中数组Array、ArrayList和List三者的区别

• 数组（）

            #region 数组
            //初始化方式_0：先声明再赋值
            string[] weekDays_0 = new string[7];
            weekDays_0[0] = "Sun";
            weekDays_0[1] = "Mon";
            weekDays_0[2] = "Tue";
            weekDays_0[3] = "Wed";//...
            //初始化方式_1：声明数组时即将其初始化...
            string[] weekDays_1 = new string[] { "Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat" };
            //初始化方式_1.5：声明数组时即将其初始化...快捷方式...
            string[] weekDays_2 = { "Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat" };
            //修改
            weekDays_0[0] = "Mon";
            #endregion

 

 

学习泛型的时候翻过来再学习下基础知识...记录一下...
