1.写一个控制台应用程序：

每1秒钟显示一个0到9的随机整数,并显示当前时间。
格式如下：
2 2009-6-22 14:30:22
1 2009-6-22 14:30:23
5 2009-6-22 14:30:24
6 2009-6-22 14:30:25
3 2009-6-22 14:30:26
1 2009-6-22 14:30:27

----------------------------------------------------------------
class Cula
    {
        public static void Print(object souce, ElapsedEventArgs e)
        {
            Random m = new Random();
            DateTime b = DateTime.Now;
            Console.WriteLine("{0,4}/t{1:G}", m.Next(10), b);

}
}

    class Program
    {
        static void Main(string[] args)
        {
            Timer myTimer = new Timer(1000);
            myTimer.Elapsed += new ElapsedEventHandler(Cula.Print);

myTimer.Start();
Console.ReadKey();

}
}
}
------------------------------------------------------------------------------
2.练习写一个控制台应用程序：随机产生10个0到50的不同的整数.

-------------------------------------------------------------------------------
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Timers;
namespace Test_000000
{
public delegate void ShowHandler(string mess);

    public class Produce
    {
        private   event ShowHandler ShowHandlerEvent;
        private static Timer myTimer;
        private static int temp=0;
        public Produce()
        {
            myTimer = new Timer(1000);
            myTimer.Elapsed += new ElapsedEventHandler(RanProduce);

}

        void RanProduce(object source, ElapsedEventArgs e)
        {
            Random ran = new Random();

           ShowHandlerEvent(ran.Next(50).ToString());
           if (temp++ ==9)
               myTimer.Stop();

        }
        public void Display(string mess)
        {

            Console.WriteLine(mess );
        }
        public void DoStart()
        {

            myTimer.Start();
        }

        static void Main()
        {
            Produce myProduce = new Produce();
            myProduce.ShowHandlerEvent += new ShowHandler(myProduce.Display );
            myProduce.DoStart();
            Console.ReadKey();
        }

}
