Geckofx get specific links from a page

Question

var links = new List<GeckoElement>();
foreach (var link in geckoWebBrowser1.Document.Links)
{
    if (!String.IsNullOrEmpty(link.GetAttribute("href").ToString()))
        links.Add(link);
    }
}

I have this code to collect all links in the page, but I cant figure it out how can I filter to some specific links that starts with for example "ow.ly". Rest in the list should be ignored.

Tryed this but didnt seem to work

if (links.Count > 0)
{
    if (links.Equals("ow.ly"))
    {

    }
}

When I debug if links equals ow.ly it shows 0 reults.

Answer 1

links is a a List<GeckoElement>. So it’s unlikely that the list equals to the string "ow.ly". Instead, you want to filter the list for items, which href property contains that text.

You could do that for example like this:

var owlyLinks = geckoWebBrowser1.Document.Links.Where(link =>
{
    string hrefAttribute = link.GetAttribute("href").ToString();
    return !string.IsNullOrEmpty(hrefAttribute) && hrefAttribute.Contains("ow.ly");
}).ToList();

You might want to adjust the check so that "ow.ly" needs to appear somewhere special instead of just somewhere inside the string. For example, you could parse the whole Url, and then check that the host name equals to ow.ly.
