C# มา โหลด โน่น โหลดนี่กันเถอะ (โปรแกรมดาวน์โหลดด้วย C#)

string strRegex = @"(https://.*?\.png)";
//คือ pattern หรือ รูปแบบ สำหรับ Regex
Regex myRegex = new Regex(strRegex, RegexOptions.None);
เป็นการเรียกใช้ Regex 
foreach (Match myMatch in myRegex.Matches(strTargetString))
{
  if (myMatch.Success)
  {
    // Add your code here
  }
}

foreach (Match myMatch in new Regex(@"(https://.*?\.png)", RegexOptions.None).Matches(strTargetString))
{
 
}

public static void LoadFByWebClient(string link, string file)
        {
            using (WebClient webClient = new WebClient())
            {
               		 try
                {
                    webClient.DownloadFileAsync(new Uri(link), file);
                    System.Threading.Thread.Sleep(100);
                }
                		catch { }

            }
        }

public static void LoadByIDM(string link, string file)
        {
            string IDMpath = Microsoft.Win32.Registry.GetValue(@"HKEY_CURRENT_USER\Software\DownloadManager", "ExePath", true).ToString();

            System.Diagnostics.Process.Start(IDMpath, "/a /n /d " + link + "  /f \"" + file + "\"");
            System.Threading.Thread.Sleep(500);
        }

foreach (Match myMatch in new Regex(@"(https://.*?\.png)", RegexOptions.None).Matches(strTargetString))
{
   LoadFByWebClient(myMatch.Groups[1].Value,@“C:\_load\” + System.IO.Path.GetFileName(_myMatch.Groups[1].Value));
}
ยังไม่จบครับ เรายังต้องทำให้ง่ายโดยการแปลงจาก url ให้เป็น โค้ดhtml ซะก่อน
public static string getHTML(string url)
        {
            string html = "";
            try
            {
                System.Net.HttpWebRequest request = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(url.Trim());
                System.Net.HttpWebResponse response = (System.Net.HttpWebResponse)request.GetResponse();
                System.IO.StreamReader sr = new System.IO.StreamReader(response.GetResponseStream());
                html = sr.ReadToEnd();
                sr.Close();
                response.Close();
            }
            catch { }
            return html;
        }

string html = TorServices.NetWorkTOR.getHTML("https://www.iconfinder.com/search/?q=C#&price=free");
//แปลงจาก url ให้เป็น html

            foreach (Match myMatch in new Regex(@"(https://.*?\.png)", RegexOptions.None).Matches(html))
            {
                LoadFByWebClient(myMatch.Groups[1].Value,@"C:\_load\" +System.IO.Path.GetFileName(myMatch.Groups[1].Value));
            }

new List<string>() { "C#", "lab", "Chemistry", "test", "metal","lern","book","man","animal","food" }
            .ForEach(cri =>
            {
                string html = TorServices.NetWorkTOR.getHTML("https://www.iconfinder.com/search/?q=" +cri+ "&price=free");
                foreach (Match myMatch in new Regex(@"(https://.*?\.png)", RegexOptions.None).Matches(html))
                {
                    TorServices.NetWorkTOR.LoadFByWebClient(myMatch.Groups[1].Value,@"C:\_load\" +System.IO.Path.GetFileName(myMatch.Groups[1].Value));
                }
            });
