我正在尝试使用 DotNetBrowser 加载多个页面，并且每次加载新的 url 时我都需要知道，

 myBro.FinishLoadingFrameEvent += delegate (object send, FinishLoadingEventArgs es)
            {        
     if (es.IsMainFrame && es.ValidatedURL.Contains("login"))
                {
                    DOMDocument document = myBro.GetDocument();
                    DOMElement user = document.GetElementById("LoginForm_login");
                    user.SetAttribute("value", "email");
                    DOMElement pass = document.GetElementById("LoginForm_password");
                    pass.SetAttribute("value", "pass");
                    DOMElement loginbtn = document.GetElementByTagName("button");
                    loginbtn.Click();

   // can't add nothing more here //

};

但是此代码仅在加载第一页时才通知我

FinishLoadingFrameEvent为网页上加载的每个框架触发 ，即使在重新加载页面之后也是如此。LoadURL调用该方法后，您可以多次使用它以在浏览器完全加载网页时收到通知。

这是基于文档文章https://dotnetbrowser.support.teamdev.com/support/solutions/articles/9000110055-loading-url-synchronously的示例代码：

ManualResetEvent waitEvent = new ManualResetEvent(false);
browser.FinishLoadingFrameEvent += delegate(object sender, FinishLoadingEventArgs e)
{
    // Wait until main document of the web page is loaded completely.
    if (e.IsMainFrame)
    {
        waitEvent.Set();
    }
};

//Load URL
browser.LoadURL("http://www.google.com");
waitEvent.WaitOne();
//The page http://www.google.com is now loaded completely

//Then, reset the event and load the next URL
waitEvent.Reset();
browser.LoadURL("http://www.microsoft.com");
waitEvent.WaitOne();
//The page http://www.microsoft.com is now loaded completely
