WebPictureDownloader

The WebPictureDownloader application solves very common problem.

#What does is solve? It downloads all the images of the webpage you want. Below I will explain the steps of the whole porcess.

• HTMLDownLoader - first it downloads the html code of the webpage(implementing IDisposable interface),
• ImageAddressExtractor - then extracts image sources using Regular Expressions,

public static void ImgCodeExtractor(string fromPath, string toPath)
 {
     string data = File.ReadAllText(fromPath);
     Regex imgRegex = new Regex("<img.+?src=[\"'](.+?)[\"'].*?>");
     MatchCollection imgMatches = imgRegex.Matches(data);
     string s = string.Empty;
     foreach (Match imgMatch in imgMatches)
     {
         s += imgMatch.Value + "\r\n";
     }
     File.WriteAllText(toPath, s.ToString());
 }


 public static string ImgCodeCorrector(string toPath, string finalPath)
 {
     string finalLine = "";
     string line;
     StreamReader file = new StreamReader(toPath);
     while ((line = file.ReadLine()) != null)
     {
         finalLine += "http://www.micarmenia.am" + Regex.Match(line, "<img.+?src=[\"'](.+?)[\"'].+?>", RegexOptions.IgnoreCase).Groups[1] + "\r\n";
     }
     File.WriteAllText(finalPath, finalLine.ToString());
     return finalLine;
 }

• ImageDownloader - after extracting images' codes, downloads all the images of the webpage using WebClient.

public static void ImgSaver(string url, int i)
{
    var desktop1 = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
    var path1 = Path.Combine(desktop1, $"img{i}.svg");

    using (var client = new WebClient())
    {
        Console.WriteLine(url);
        Uri uri = new Uri(url);
        client.DownloadFileAsync(uri, path1);
        i++;
    }
}


public static void AllImgSaver(string finalPath)
{
  Console.WriteLine(finalPath);
   StreamReader swr = new StreamReader(finalPath);
  string line = string.Empty;
  int i = 1;
  Console.WriteLine(line);
 while ((line = swr.ReadLine()) != null)
  {
      Console.WriteLine(line);

      ImgSaver(line, i);
      i++;

  }

swr.Close();
}
