推荐答案

如果你使用 WebBrowser 类 [< a href =http://msdn.microsoft.com/en-us/library/system.windows.forms.webbrowser.aspxtarget =_ blanktitle =New Window> ^ ]，然后您可以直接从 Document 属性获取DOM，该属性是 HtmlDocument 类 [ ^ ]。

If you use the WebBrowser Class[^], then you can get the DOM direct from the Document property, which is an instance of the HtmlDocument Class[^].

此代码从一个继承自的控件中获取HTML WebBrowser，并使用DOM查找其中的特定表和项。

This code gets the HTML from a control that is inherited from WebBrowser, and uses the DOM to find particular tables and items within it.

// logout from 3Rings
HtmlElement element = Document.GetElementById("directory_list");

// get the table header collection (one element)
HtmlElementCollection trCollection = element.GetElementsByTagName("THEAD");
// get the header items collection
trCollection = trCollection[0].GetElementsByTagName("TH");
int xName = -1;
int xEmail = -1;
int nIndex = 0;
foreach (HtmlElement trItem in trCollection)
{
	Debug.WriteLine(trItem.InnerText);
	string strHeading = trItem.InnerText.Trim().ToLower();
	if (strHeading.Equals("name"))
		xName = nIndex;
	if (strHeading.Equals("email"))
		xEmail = nIndex;
	nIndex++;
}
