c#多线程

public partial class Form1 : Form { Thread uithread; public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { //下面一行避免出现：线程间操作无效: 从不是创建控件 的线程访问它 Control.CheckForIllegalCrossThreadCalls = false; uithread = new Thread(new ThreadStart(this.up1)); uithread.Start(); } private void button2_Click(object sender, EventArgs e) { label2.Text = "good"; } void up1() { //Label l1 = new Label(); //Form1. for (var i = 0; i < 1000; i++) { System.Threading.Thread.Sleep(1000); this.label1.Text = i.ToString(); } } private void button3_Click(object sender, EventArgs e) { uithread.Abort(); } } 

 

还有个Application.DoEvents() 可以解决界面响应问题，不过效率低。
