定时器-随机数

1.　定时器

using System.Timers;

Timer mytimer = new Timer(100);

mytimer.Elapsed += new ElapsedEventHandler(mytimer_Elapsed);
mytimer.Start();

   void mytimer_Elapsed(object sender, ElapsedEventArgs e)
    {
      可以输出控制台数据，但不能输出网站数据，为什么？
    }

2.随机数

        Random rn = new Random();
      1  rn.Next(10);0-9
      2  rn.NextDouble() 0.0-1.0
        byte[] b=new byte [10];
      3 rn.NextBytes(b);
        foreach (byte kk in b)
        {
            Response.Write(kk + "<br/>");
        }
