如何为webBrowser导航事件设置超时

webBrowser1.Navigating += new WebBrowserNavigatingEventHandler(webBrowser_Navigating);

private Timer timer;

private void webBrowser_Navigating(object sender, WebBrowserNavigatingEventArgs e)
{
    // 设置超时时间为10秒
    int timeout = 10000;

    // 创建定时器
    timer = new Timer(timeout);
    timer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
    timer.Enabled = true;
}

private void OnTimedEvent(object source, ElapsedEventArgs e)
{
    // 超时操作，例如取消导航或显示错误信息
    timer.Enabled = false;
    // 取消导航
    webBrowser1.Stop();
    // 显示错误信息
    MessageBox.Show("导航超时，请检查网络连接或重试。");
}
