I was just interested in trying out threads in C#, so here's just an example usage!

threads.cs

using System.Text.RegularExpressions;

partial class Program
{
    static readonly HttpClient client = new();

    static void Main(string[] args)
    {
        int threadCount = 10;
        Thread[] threads = new Thread[threadCount];
        Console.WriteLine($"Starting {threadCount} threads to get some random wikipedia articles!\n");

        for (int i = 0; i < threadCount; i++)
        {
            threads[i] = new Thread(() => VisitRandomWikipediaPage(i));
            threads[i].Start();
        }

        foreach (var Thread in threads)
        {
            Thread.Join();
        }
        Console.WriteLine("All threads are done for.");
    }

    static void VisitRandomWikipediaPage(int threadNum)
    {
        string url = "https://en.wikipedia.org/wiki/Special:Random";
        try
        {
            HttpResponseMessage response = client.GetAsync(url).Result;
            response.EnsureSuccessStatusCode();
            string responseBody = response.Content.ReadAsStringAsync().Result;

            Console.WriteLine($"  [Thread {threadNum}] Visited a random Wikipedia page!");
            // possible dereference here
            Console.WriteLine($"  [Thread {threadNum}] Redirected URL: {response.RequestMessage?.RequestUri}");

            string title = ExtractTitle(responseBody);
            Console.WriteLine($"  [Thread {threadNum}]     Page Title: {title}\n");
        }
        catch (HttpRequestException e)
        {
            Console.WriteLine($"\n  [Thread {threadNum}] Exception caught umu!");
            Console.WriteLine($"  [Thread {threadNum}] Message :{0} ", e.Message);
        }
    }

    static string ExtractTitle(string html)
    {
        var regex = TitleRegex();
        var match = regex.Match(html);

        if (match.Success)
        {
            // innerHTML of a h1 tag
            string innerHtml = match.Groups[1].Value;

            // Remove all HTML tags
            return HTMLTagsRegex().Replace(innerHtml, "").Trim();
        }

        return "Title not found";
    }

    // Ну да, регекс для HTML, а что? Что ты мне сделаешь, а?
    [GeneratedRegex("<h1[^>]*id=['\"]firstHeading['\"][^>]*>(.*?)</h1>", RegexOptions.Singleline)]
    private static partial Regex TitleRegex();
    [GeneratedRegex("<.*?>")]
    private static partial Regex HTMLTagsRegex();
}
