Question

您好）请帮助我，我需要按下按钮让线程睡眠，然后按下按钮1继续此线程。我处理WPF，当我在button1_click事件中调用WaitOne（）方法时，我的表单变得冻结，我无法点击任何按钮。这是我的代码示例：

AutoResetEvent objAuto = new AutoResetEvent(false);
    private void Button_Click(object sender, RoutedEventArgs e)
    {

        if (thread != null)

        {

            objAuto.Set();
        }
        thread = new Thread(new ThreadStart(zoo.FeedAnimals));
            thread.Start();
}

private void Button_Click_1(object sender, RoutedEventArgs e)
    {          
        objAuto.WaitOne();
    }

感谢您提前

冻结的原因是因为你在UI线程上调用WaitOne。你可能想要一些东西

AutoResetEvent objAuto = new AutoResetEvent(false);
private void Button_Click(object sender, RoutedEventArgs e)
{   
    thread = new Thread(new ThreadStart(zoo.FeedAnimals));
    thread.Start();
}

private void Button_Click_1(object sender, RoutedEventArgs e)
{       
    if (thread != null)
    {
        objAuto.Set(); // this is in the main UI thread
    }       
}

public void FeedAnimals()
{   
    ...
    objAuto.WaitOne(); // this blocks your other thread
    ...
}

单击按钮时停止并继续线程
