在WinForm中，如何获取一个Web页面元素的所有属性啊

Question

比如可以用getAttribute("Name")
来获取元素的属性，可是如果不知道这个元素有哪些属性，怎样才能把这个元素的所有属性都列出来呢。
比如
<IFRAME style="WIDTH: 100%; HEIGHT: 100%" src="showOutlookMenu.do?MenuID=2" frameBorder=no></IFRAME>
我要能获取到
WIDTH: 100%
HEIGHT: 100%
src="showOutlookMenu.do?MenuID=2
frameBorder=nowinformgetAttribute

Answer 1

连个id都没有，怎么找，你还不如获取html代码，用正则解析呢

Answer 2

用webbrowser控件加载这个页面然后： HTMLDocument doc = (HTMLDocument)webBrowser1.Document.DomDocument;
 object j;
 for (int i = 0; i < doc.parentWindow.frames.length; i++)
 {
   j = i;
   HTMLWindow2Class frame = doc.parentWindow.frames.item(ref j) as HTMLWindow2Class;
  IHTMLDocument2 doc = (IHTMLDocument2)frame.Document.DomDocument;
   //这里分析doc
  }

类似这个        private void webBrowser2_ProgressChanged(object sender, WebBrowserProgressChangedEventArgs e)
        {
            if (e.CurrentProgress == e.MaximumProgress)
            {
                HtmlElement table = webBrowser2.Document.All["insTable"];
                if (table != null && !_chang)
                {
                    _chang = true;
                    string getNumList = dgv_Reg.Rows[int.Parse(_lastNum) - 1].Cells["TZNum"].Value.ToString();
                    int deposit = int.Parse(lb_total.Text.Trim()) / getNumList.Split(',').Length;
                    HtmlElementCollection tr = table.GetElementsByTagName("tr");
                    for (int i = 1; i < tr.Count; i++)
                    {
                        if (getNumList.Contains(i.ToString()))
                        {                            foreach (HtmlElement tag in tr[i].GetElementsByTagName("input"))
                            {
                                if (tag.GetAttribute("name") == "ck_")
                                {
                                    tag.InvokeMember("click");
                                }
                                if (tag.GetAttribute("name") == "SMONEY")
                                {
                                    tag.SetAttribute("value", deposit.ToString());
                                }
                                if (tag.GetAttribute("name") == "Submit")
                                {
                                    tag.InvokeMember("click");
                                }
                                if (tag.GetAttribute("name") == "Submit2")
                                {
                                    tag.InvokeMember("click");
                                }
                            }                            dgv_Log.Rows.Insert(0, new object[] { DateTime.Now.ToString(), (int.Parse(_lastCycle) + 1), i.ToString() + "投" + deposit.ToString() });
                        }
                    }
                    foreach (HtmlElement tag in webBrowser2.Document.GetElementsByTagName("input"))
                    {
                        if (tag.GetAttribute("value") == "确认投注")
                        {
                            tag.InvokeMember("click");
                            break;
                        }
                    }
                    PageRefresh();
                    time_Refresh.Enabled = true;
                }
            }
        }
