C#中线程与窗体交互的多线程编程实例2014-10-13
代码：
public partial class Form1 : Form{//声明线程数组Thread[] workThreads = new Thread[10]; public Form1（）{InitializeComponent（）;} //此委托允许异步的调用为Listbox添加Itemdelegate void AddItemCallback（string text）; //这种方法演示如何在线程安全的模式下调用Windows窗体上的控件。private void AddItem（string text）{if （this.listBox1.InvokeRequired）{AddItemCallback d = new AddItemCallback（AddItem）;this.Invoke（d, new object[] { text }）;}else{this.listBox1.Items.Add（text）;}} //数据采集方法public void DataGet（）{while （true）{AddItem（"ok"）;Thread.Sleep（1000）;}//如果此方法退出了，那么这个线程也就退出了} /// <summary>/// 启动线程/// </summary>/// URL：http://www.bianceng.cn/Programming/csharp/201410/45776.htm/// <param name="sender"></param>/// <param name="e"></param>private void button1_Click（object sender, EventArgs e）{//循环创建并启动线程执行for （int i = 0; i < workThreads.Length; i++）{if （workThreads[i] == null）{//如果线程不存在，则创建workThreads[i] = new Thread（new ThreadStart（DataGet））;workThreads[i].Name = i.ToString（）;workThreads[i].Start（）;}else{//已经存在，如果没有运行，则启动if （workThreads[i].ThreadState == ThreadState.Aborted || workThreads[i].ThreadState == ThreadState.Stopped）{workThreads[i] = new Thread（new ThreadStart（DataGet））;workThreads[i].Name = i.ToString（）;workThreads[i].Start（）;}else{workThreads[i].Start（）;}}}} /// <summary>/// 停止线程/// </summary>/// <param name="sender"></param>/// <param name="e"></param>private void button2_Click（object sender, EventArgs e）{//循环停止线程执行for （int i = 0; i < workThreads.Length; i++）{//如果线程存在，并且状态不是停止也不是终止的，则终止该线程if （workThreads[i] ！= null && workThreads[i].ThreadState ！= ThreadState.Stopped && workThreads[i].ThreadState ！= ThreadState.Aborted）{workThreads[i].Abort（）;}}}}
