How to extract image urls from HTML File in C#

Question

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

Answer 1

I think I need more information about your problem... But try to search for a regular expression containing "img src= ..>"

maybe something like '#<\s*img [^>]src\s=\s*(["\'])(.*?)\1#im'

You can read something about this problem in this article

Answer 2

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));
}
