How to search for an element in a c# tree?

Question

C++ / C#

Good afternoon, there is such a piece of Python code, it works fine for me, there are no problems with it, but I would like to rewrite it in c#

if 'Сменить интерфейс' in main_page.text and 'iframe-topline-table' in main_page.text:  # если активирована полная версия игры\
            print('была полная версия сайта,сменили')
            web_page = html.fromstring(main_page.content)
            for i in web_page.xpath('//a/@href'):

                if '?sr_method=changeInterface' in i:
                    change_i_link = i

What libraries do I need in this case?

As long as I don't have anything

var url = "https://steamcommunity.com/?l=russian";
            var httpClient = new HttpClient();
            var html = await httpClient.GetStringAsync(url);
            Console.WriteLine(html);

How can I go through the source (html) and extract the entire url from the href, for example, where it is - "browsefilter=mostrecent"

I'm not asking you to write for me, I need a kick (libraries, etc.)
Thanks

Use Html Agility Pack to work with html.
