远程注册表读取,与多线程池的应用.

界面如下:


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);
                }

                    Interlocked.Increment(

            }
