DotNetBrowser FinishLoadingFrameEvent多用途

Question

我正在尝试使用DotNetBrowser加载多个页面，我需要知道每次加载新的url时，

 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 //

};

但是这段代码只有在加载第一个页面时才会通知我

加载到网页上的每个帧都会触发FinishLoadingFrameEvent，即使在页面重新加载之后也是如此。您可以多次使用它，以便在调用LoadURL方法后浏览器已完全加载网页时收到通知。

以下是基于文档文章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
