Answer 1

当然是通过使用定时器。例如:

    public void NavigateTo(Uri url) {
        webBrowser1.Navigate(url);
        timer1.Enabled = true;
    }

    private void timer1_Tick(object sender, EventArgs e) {
        timer1.Enabled = false;
        MessageBox.Show("Timeout on navigation");
    }

    private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) {
        if (e.Url == webBrowser1.Url && timer1.Enabled) {
            timer1.Enabled = false;
            // etc..
        }
    }
