使用线程的问题 [英] problem with using thread

问题描述

Hi
i想要计数0到1000并使用线程在文本框中写入

这是我的代码，但它没有做，几秒后它转到debugger.break（）;

我该怎么做才能正确运行？

Hi i want to count 0 to 1000 and write in textbox using thread
this is my code but its not doing and after a few second it go to debugger.break();
what should i do to it run correctly?

private void loop()
{
    while (check == true)
    {
        Dispatcher.BeginInvoke(() =>
           {
               for (int i = 0; i < 1000; i++)
               {
                   Thread.Sleep(100);
                   txtResult.Text = i.ToString();
               }
           });
    }
}

private void btnClick_Click(object sender, RoutedEventArgs e)
{
    check = true;
    ThreadStart st = new ThreadStart(loop);
    Thread s = new Thread(st);
    s.Start();
}

推荐答案

现在，你继续调用一个调度程序线程上的方法从0到1000循环，并且它在该循环中阻止调度程序线程100毫秒。你不应该阻止调度程序线程，只阻止你的循环线程。另外，我想你可能想要一个 if 而不是而。



试试这个：

Right now, you keep invoking a method on the dispatcher thread that loops from 0 to 1000, and it blocks the dispatcher thread 100 milliseconds while it is in that loop. You should not be blocking the dispatcher thread, only block your loop thread. Also, I think you probably want an if instead of a while.

Try this:

private void loop()
{
    if (check)
    {
        for (int i = 0; i < 1000; i++)
        {
            Thread.Sleep(100);
            Dispatcher.Invoke(() =>
            {
                txtResult.Text = i.ToString();
            }
        }
    }
}
