当然使用计时器。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..
}
}

我正在使用基于Navigating
和Navigated
事件的以下方法。观察这两个事件之间的时间重定向到家庭藻类。
//Navigation Timer
timer2.Enabled = true;
timer2.Interval = 30000;
br.DocumentCompleted += browser_DocumentCompleted;
br.DocumentCompleted += writeToTextBoxEvent;
br.Navigating += OnNavigating;
br.Navigated += OnNavigated;
br.ScriptErrorsSuppressed = true;
br.Navigate(ConfigValues.websiteUrl);
private void OnNavigating(object sender, WebBrowserNavigatingEventArgs e)
{
//Reset Timer
timer2.Stop();
timer2.Start();
WriteLogFunction("OnNavigating||||||"+e.Url.ToString());
}
private void OnNavigated(object sender, WebBrowserNavigatedEventArgs e)
{
//Stop Timer
timer2.Stop();
WriteLogFunction("NAVIGATED <><><><><><><> " + e.Url.ToString());
}
private void timer2_Tick(object sender, EventArgs e)
{
WriteLogFunction(" Navigation Timeout TICK");
br.Stop();
br.Navigate(ConfigValues.websiteUrl);
}
