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();
