GUID：

　　产生一个不会重复的ID

        static void Main(string[] args)
        {
            //产生一个不会重复的编号
            Console.WriteLine(Guid.NewGuid().ToString());
            Console.WriteLine(Guid.NewGuid().ToString());
            Console.WriteLine(Guid.NewGuid().ToString());
            Console.WriteLine(Guid.NewGuid().ToString());
            Console.WriteLine(Guid.NewGuid().ToString());
            Console.ReadKey();
        }
