C#_Stack的使用方法

            // Stack存放的数据类型是Object类型，所以可以同时存放整形和字符串                Stack stack = new Stack();            stack.Push(1);            stack.Push(2);            stack.Push(3);            stack.Push(4);            stack.Push(5);            stack.Push("cxm");            foreach (var item in stack)            {                Console.WriteLine(item);            }            stack.Push(6);            stack.Pop();            Console.WriteLine("Count:" + stack.Count);            while (stack.Count > 0)            {                Object num = stack.Pop();                Console.WriteLine(num);            }            Console.ReadLine();
