OrderBy和OrderByDescending排序

昨天有練習對數字陣列進行排序，《C#陣列Array排序》https://www.cnblogs.com/insus/p/10825174.html

其實一切都弄得很複雜，array已經有2個方法OrderBy和OrderByDescending：

參考下麵代碼演示：

 int[] ints = { 10, 45, 15, 39, 21, 26 };
           
            foreach (var i in ints.OrderBy(g => g))
            {
                System.Console.Write(i + " ");
            }


            Console.WriteLine();
            var str = new string('-', 10);
            Console.Write(str);
            Console.WriteLine();

            
            foreach (var i in ints.OrderByDescending(g => g))
            {
                System.Console.Write(i + " ");
            }
            Console.WriteLine();

按Ctrl + F5運行控制台程式：
