远程注册表读取,与多线程池的应用

一般用在域环境下,读取客户机注册的配制信息.
主要代码如下:

private void button1_Click(object sender, System.EventArgs e)
        {
            tabControl1.SelectedIndex=1;

            ThreadStart threadDelegate = new ThreadStart(this.doIt);
            Thread newThread = new Thread(threadDelegate);
            newThread.Start();

        }
        private int number = 0;
        private void doIt()
        {
            int maxthread = int.Parse(txt_numThread.Text);
            string remoteName;
            progressBar1.Value = 0;
            progressBar1.Maximum =(int)n_ip2.Value-(int)n_ip1.Value;
            for(Decimal i = n_ip1.Value;i<=n_ip2.Value;i++)
            {
                remoteName = txt_ipStart.Text+"."+i.ToString();

                WaitCallback async = new WaitCallback(RunGet);
                while(true)
                {
                   
                    Monitor.Enter(number);
                    if(number>5)
                        Thread.Sleep(1000);
                    else
                        break;
                    Monitor.Exit(number);
                }
                if(ThreadPool.QueueUserWorkItem(async,remoteName))
                    Interlocked.Increment(ref number);

            //RunGet(remoteName);
            }
            while(true)
            {
                //myResetEvent.Set();
                Monitor.Enter(number);
                if( number <= 0)
                    break;
                else
                    Thread.Sleep(1000);
                Monitor.Exit(number);
            }
            MessageBox.Show("完成");

           
        }

        private void RunGet(object ip)
        {
            try
            {
                RegistryKey environmentKey = null;
