我所拥有的很简单，一个带有 webbrowser-controll 的表单。

该网络浏览器访问一个网站。这一切都有效。

但是当他在页面上时我不想做的是让他运行一些 javascript 代码（或 jQuery，如果可能的话）来获取<b></b>网站上标签之间的所有文本。

我该怎么做？

编辑： 感谢Birk，代码现在看起来像这样：

HtmlElementCollection bigFontTags = webBrowser1.Document.GetElementById("Frame_A").Document.GetElementsByTagName("b");
            string[] textPieces = new string[bigFontTags.Count];
            for (int i = 0; i < bigFontTags.Count; i++) {
                textPieces[i] = bigFontTags[i].InnerText;
            }
            //process text
            string bigText = String.Join(" ", textPieces);
            MessageBox.Show(bigText);

但这不起作用。那是因为我需要获取的元素在框架和框架集的深处......这是布局（简单）：

<frameset rows="0,1000" border="0" frameborder="0">

    <frame src="/mail/Login?domain=telfort.nl&amp;style=default&amp;plain=0" name="SContentFrame" id="SContentFrame" scrolling="Auto" noresize="">
    <frameset rows="88,*" framespacing="0" frameborder="0" border="0" bordercolor="#FFFFFF">

        <frameset cols="182,*" framespacing="0" frameborder="0" border="0" bordercolor="#FFFFFF" onunload="ExitLogout()" onload="LoadFrames('/mail/Navigation?sid=1FBE4F29181F18D9358ABC082C7DEE1B6C67481B&amp;userid=marcmeesters%40telfort.nl&amp;seq=+Q&amp;auth=+A&amp;style=default','/mail/MessageList?sid=1FBE4F29181F18D9358ABC082C7DEE1B6C67481B&amp;userid=marcmeesters%40telfort.nl&amp;seq=+Q&amp;auth=+A&amp;srcfolder=INBOX&amp;chk=1&amp;style=default')">

        <frame src="/supp/blank.htm" name="Frame_A" id="Frame_A" frameborder="0" scrolling="Yes" marginwidth="0" marginheight="0" bordercolor="#FFFFFF" border="0">
        <form name="phoenix" method="post" action="" onsubmit="return clickedButton">
And then are here some tables and the content that i want to get.....

那么我怎样才能从那里得到那个内容？？？（以一种很好的方式？？？）

EDIT2： 我将发布网站的生成源：（注意！我已经删除了所有不相关的内容......所以只有从开始到内容的方式）

编辑3： 感谢Birk，问题解决了，这就是答案：

HtmlWindow SContentFrame = webBrowser1.Document.Window.Frames[1];
            HtmlWindow Frame_A = SContentFrame.Document.Window.Frames[2];
            HtmlElementCollection bigFontTags = Frame_A.Document.GetElementsByTagName("b");
            string[] textPieces = new string[bigFontTags.Count];
            for (int i = 0; i < bigFontTags.Count; i++) {
            textPieces[i] = bigFontTags[i].InnerText;
            }
            string bigText = String.Join(" ", textPieces);
            MessageBox.Show(bigText);

创建一个 DocumentCompleted-event 并使用((WebBrowser)sender).Document.GetElementsByTagName("b");.

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            HtmlElementCollection bigFontTags = ((WebBrowser)sender).Document.GetElementsByTagName("b");
            string[] textPieces=new string[bigFontTags.Count];
            for (int i = 0; i < bigFontTags.Count; i++)
            {
                textPieces[i] = bigFontTags[i].InnerText;
            }
            //process text
            string bigText = String.Join(" ", textPieces);
            MessageBox.Show(bigText);
        }

这不是 JavaScript，但结果完全相同。

编辑#2：对于所有可以使用的嵌套框架：

HtmlElementCollection bigFontTags = webBrowser1.Document.GetElementById("SContentFrame").Document.GetElementById("SContentFrame").Document.GetElementById("Frame_A").Document.GetElementsByTagName("b");

如果我正确理解您的框架集结构，那应该可以。
