从 Mono WebBrowser 控件访问 HTML DOM？

Question

使用 .NET 的 Windows 窗体 Webbrowser 控件，访问 DOM 非常容易。考虑这种情况

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

现在，假设您的 html 页面中有一个测试 javascript 方法，该方法接受字符串参数。因此，一旦加载完成，您就可以

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

现在，我正在尝试在 Mono 中运行它。在运行时，Mono 应该使用 Mono 的 Web 浏览器控件 - http://www.mono-project.com/WebBrowser 。我发现一些非常奇怪的行为（请参阅更新）

问题是，如何通过 Mono 的网络浏览器控件访问 HTML DOM，可能调用脚本？

更新

刚刚注意到，仅当我连接到网络时，webBrowser1.Document 才为空。否则，如果我处于离线状态，脚本实际上会被调用，但之后 Mono 运行时崩溃，并出现此错误

它应该可以工作，但不幸的是，每次 Mozilla 发布更新时，事情都会比我希望的要严重得多。你是在windows还是linux上做这个的？您安装的 xulrunner 版本是什么？
