C#多线程编程实例 线程与窗体交互
代码：
public partial class Form1 : Form { //声明线程数组 Thread[] workThreads = new Thread[10]; public Form1() { <a style="color:transparent">本文来源gao($daima.com搞@代@#码$网</a> InitializeComponent(); } //此委托允许异步的调用为Listbox添加Item delegate 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> /// <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(); } } }
