InitializeComponent();
}现在用一个用U程控制的进E条来说明，大致的步骤如下：(x)
1Q创建Invoke函数Q大致如下：(x)
/// <summary>
/// Delegate function be invoked by main thread
/// </summary>
private void InvokeFun()
{
if(prgBar.Value< 100)
prgBar.Value = prgBar.Value + 1;
}
2Q子U程入口函数Q?nbsp;
/// <summary>
/// Thread function interface
/// </summary>
private void ThreadFun()
{
// Create invoke method by specific function
MethodInvoker mi = new MethodInvoker(this.InvokeFun);
for(int i=0; i<100; i++)
{
this.BeginInvoke(mi);
Thread.Sleep(100);
}
}
3.创徏子线E：(x)
Thread thdProcess = new Thread(new ThreadStart(ThreadFun));
thdProcess.Start();
Ҏ(gu)二：(x)
加入该句QControl.CheckForIllegalCrossThreadCalls = False 取消U线E安全保护模式！
Ҏ(gu)三：(x)带参?br />
使用cR类的方法或cȝ属性都可以向线E传递参敎ͼ(x)
public class UrlDownloader
{
string url;
public UrlDownloader (string url)
{
this.url = url;
}
public void Download()
{
WebClient wc = new WebClient();
Console.WriteLine("Downloading " + url);
byte[] buffer = wc.DownloadData (url);
string download = Encoding.ASCII.GetString(buffer);
Console.WriteLine(download);
Console.WriteLine("Download successful.");
//q里你可以将downloadq行保存{处?.....
}
}
[... 在另一个类中用它?..]
UrlDownloader downloader = new UrlDownloader (yourUrl);
new Thread (new ThreadStart (downloader.Download)).Start();
注意参数是如何传递的?/p>
Ҏ(gu)四：(x)带参?br />
ThreadStart starter = delegate { Download(yourUrl); };
new Thread(starter).Start();
//使用U程?br />
WaitCallback callback = delegate (object state) { Download ((string)state); };
ThreadPool.QueueUserWorkItem (callback, yourUrl);
Ҏ(gu)五：(x)带参?/strong>
Thread t = new Thread (new ParameterizedThreadStart(DownloadUrl));
t.Start (myUrl);
static void DownloadUrl(object url)
{
// ....
}
