您可能需要使用一些第三方工具. HTMLAgilityPack是一种开放式源工具，可以用于此目的.
例如，要获取描述，您只需编写一小段代码

You probably need to use some third party tool. HTMLAgilityPack is one open soure tool which can be useful for the purpose.
For example to get description you can simply write a small code

HtmlDocument myDoc = new HtmlDocument();
myDoc.Load(path);
HtmlNode descNode = doc.DocumentNode.SelectSingleNode("//meta[@name='description']");
if (descNode != null) 
{
    string desc = descNode.GetAttributeValue("content", "");
}
