Thread Safe 替代 Thread.Sleep，允许 C# 中的浏览器活动

我需要一个简单的等待函数，它允许浏览器事件处理并且是线程安全的。一位同事说，在使用多个线程时，永远不要使用 DoEvents。

我注意到当我使用Thread.Sleep(10000);时，我的浏览器活动会暂停，直到睡眠完成。

任何人都可以推荐替代方案吗？

下面是一些要查看的代码：

    public static int f_sleep(int time)
    {
        System.DateTime now = System.DateTime.Now;
        System.TimeSpan duration = new System.TimeSpan(0, 0, 0, time);
        System.DateTime then = now.Add(duration);

        Thread this_thread = Thread.CurrentThread;
        while (then > DateTime.Now)
        {
            //MessageBox.Show("NewTime:" + then + "Now:" + DateTime.Now);
            //we do not want to use this because it's said to mess up multithreading
            Application.DoEvents();
            //Thread.CurrentThread.Sleep(10);
            Thread.Sleep(10);
        }           
        return 1;
    }
    private void f_run_selected_campaigns(object sender, EventArgs e)
    {
        jobs_datagrid.EndEdit();
        int count_active = 0;
        foreach (DataGridViewRow row in jobs_datagrid.Rows)
        {
            //MessageBox.Show(row.Cells[1].Value.ToString());
            if (row.Cells[1].Value.ToString() == "True")
            {
                count_active++;

                //troubleshooting
                Thread this_thread = new Thread(() =>
                    this.Invoke((MethodInvoker)delegate
                    {
                        test("hello");
                    }
                ));
                //threading properties
                this_thread.Name = "thread_" + row.Cells[0].Value.ToString();
                this_thread.IsBackground = true;
                this_thread.Start();
            }
        }
        if (count_active == 0)
        {
            MessageBox.Show("No campaigns are selected!");
        }
    }
    private void test(string this_string)
    {
        MessageBox.Show(this_string);
        //Thread.Sleep(1000);
        f_sleep(10); //for some reason Thread.Sleep does not work well with my browser loading waiting so I drew this up to create a temp pause in the code logic, but it's causing my threads to not run asychronously
        MessageBox.Show("Thread Done");
    }

我仍然无法找到解决方案。我认为会有一个简单的方法可以暂停逻辑流，同时允许UI元素和Web浏览器处理。

现在我正在使用这两个来满足我的处理需求，当我多线程时，这是否会回来咬我......我不知道。

    private int WaitBrowserLoading(Control browser)
    {
        lock(_locker)
        {
            tabcontrol_browser.Invoke((MethodInvoker) delegate {
                for (int i = 0; i < 1000000; i++)
                {
                    if(((WebBrowser)browser).ReadyState != WebBrowserReadyState.Complete)
                    {
                        Application.DoEvents();
                        Thread.Sleep(10);
                    }else
                    {
                    break;
                    }
                } 
            });
            return 1;
        }
    }
    public static int f_sleep(int time)
    {
        System.DateTime now = System.DateTime.Now;
        System.TimeSpan duration = new System.TimeSpan(0, 0, 0, time);
        System.DateTime then = now.Add(duration);
        while (then > DateTime.Now)
        {
            Application.DoEvents();
            Thread.Sleep(10);
        }
        return 1;
    }

System.Windows.Forms.Timer myTimer = new System.Windows.Forms.Timer();
public Form1()
{
    myTimer.Interval = 1000;
    myTimer.Tick += new EventHandler(myTimer_Tick);
    myTimer.Start();
    //Do stuff. 
}
void myTimer_Tick(object sender, EventArgs e)
{
    myTimer.Stop();
    //Do stuff when it ticks.
}

new Thread(() =>
{
    Thread.Sleep(10000);
    // do stuff
}).Start();
// and we're back, immediately
