//第一个program类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Collections;
using System.IO;
using System.Text;
using System.Threading;

namespace AboutTheardTest

        {
            Thread t_W, t_R;

            t_W = new Thread(new ThreadStart(wt.first));
            t_R = new Thread(new ThreadStart(rf.Reader));
            t_W.Priority = ThreadPriority.Highest;
            t_R.Priority = ThreadPriority.Normal;
            t_W.Start();
