How to extract image urls from HTML File in C#

问题

Can anyone help me by explaining how to extract image urls from HTML File in C#

回答1:

The HTML Agility Pack can do this - just use a query like //img and access the src - like so:

string html;
using (WebClient client = new WebClient()) {
    html = client.DownloadString("http://www.google.com");
}
HtmlDocument doc = new HtmlDocument();        
doc.LoadHtml(html);
foreach(HtmlNode img in doc.DocumentNode.SelectNodes("//img")) {
    Console.WriteLine(img.GetAttributeValue("src", null));
}
