從Mono WebBrowser控件訪問HTML DOM？

對Windows窗體使用.NET的Webbrowser控件，訪問DOM非常容易。考慮這種情況從Mono WebBrowser控件訪問HTML DOM？

this.webBrowser1.Navigate 
      (Path.Combine(Application.StartupPath,"TestPage.html"));

現在，假設你已經測試JavaScript方法在你的HTML頁面，它接受一個字符串PARAM。所以，一旦加載完成，你可能會

webBrowser1.Document.InvokeScript("test", new object[] { "hi" });

現在，我試圖在單聲道中運行此。在運行時，Mono應該使用Mono的網絡瀏覽器控制 - http://www.mono-project.com/WebBrowser。我發現一些非常奇怪的行爲（請參閱更新）

問題是，如何通過Mono的webbrowser控件訪問HTML DOM，可能調用腳本？

更新

就指出，webBrowser1.Document爲空，只有當我連接到網絡。否則，如果我下線，該腳本實際上是越來越調用，但在此之後，該單聲道運行時崩潰，這個錯誤

它應該可以工作，但不幸的是，每次mozilla拋出更新時，事情都會比我想要的更多。你在windows或linux上做這個嗎？你安裝了哪個xulrunner版本？

此問題出現在Windows上，單機版本2.6.7 - 檢查Xulrunner版本後會回來。謝謝 – amazedsaint 2010-10-05 16:59:30
