请教一个多线程的小问题

[popnet]

public partial class Form1 : Form
{
Thread myThread = null;
public Form1()
{
InitializeComponent();
Form1.CheckForIllegalCrossThreadCalls = false;
myThread = new Thread(new ThreadStart(myThreadEvent));
myThread.Start();
}

public void myThreadEvent()
{
while (true)
{
textBox1.Text += "myThread is running!\n";
Thread.Sleep(500);
}


}
private void button1_Click(object sender, EventArgs e)
{
Thread.Sleep(3000);
}
为什么单击button之后没有显示"myThread is running!"

实在不明白 大家帮忙解释下，先谢过了。

textBox1.Text += "myThread is running!\n";
这句应该用代理作

這裡是線程的同步問題
这样写的线程是同步现成，就是说如果你的Thread没有执行完事不会回到form的页面刷新中去的，你也就看不到显示的字了
你可以设置下
myThread.IsBackground = true;

这样主线程和myThread就可以异步进行了。。

我在机子上尝试是可以显示的，没设我说的那个值。。呵呵 ，反正设了肯定行的

[hhc123]

public Form1() 
        { 
            InitializeComponent(); 
            Form1.CheckForIllegalCrossThreadCalls = false; 
            myThread = new Thread(new ThreadStart(myThreadEvent)); 
            myThread.Start(); 
        } 

已经在构造里了还用得着单击吗

改到Console里面去检查吧！直观一些

[hhc123]

Thread.Sleep(3000); //你要等一下才会出现，你要等不了设成1000啊

[Quote=引用 1 楼 hhc123 的回复:]
C# codepublic Form1()
{
InitializeComponent();
Form1.CheckForIllegalCrossThreadCalls=false;
myThread=new Thread(new ThreadStart(myThreadEvent));
myThread.Start();
}已经在构造里了还用得着单击吗

就是，你要单击响应的话，改到单击事件里实现三

你要单击响应的话，改到单击事件里实现
