在Web浏览器中返回HtmlElement的所有属性

Question

我需要从我的webbrowser中获取所有属性.当前,我正在使用GetAttribute(),但这样,我需要知道属性的名称.想象一下,我不知道我的webbrowser中有什么.我的C#代码:

        StringWriter strWriter = new StringWriter();            
        XmlWriter xWriter = XmlWriter.Create(strWriter, new XmlWriterSettings() { Indent = true });
        xWriter.WriteStartElement("Items");
        foreach (HtmlElement el in webBrowser1.Document.GetElementsByTagName("TEXTAREA"))
        {
            xWriter.WriteStartElement("Item");
            xWriter.WriteElementString("GUID", el.Id);
            xWriter.WriteElementString("Type", el.GetAttribute("type").ToUpper());
            xWriter.WriteElementString("Name", el.Name);
            xWriter.WriteElementString("Value", el.GetAttribute("value"));
            xWriter.WriteElementString("MaxLength", el.GetAttribute("maxlength"));
            xWriter.WriteEndElement();
        }

我搜索了很多,但我没有找到任何有用的东西.

我还没有尝试过，但我想这可能是一个解决方案或第一步。首先，你必须参考microsoft.mshtml

foreach (HtmlElement el in webBrowser1.Document.GetElementsByTagName("TEXTAREA"))
{

    HTMLTextAreaElement textarea = (HTMLTextAreaElement)el.DomElement;

    xWriter.WriteStartElement("Item");
    xWriter.WriteElementString("GUID", el.Id);

    foreach (var attribute in textarea.attributes)
    {
         String name = attribute.name;
         String value = attribute.value;

         xWriter.WriteElementString(name, value);
    }

    xWriter.WriteEndElement();
}
