Job ID: 33777966

Budget: $10 – $30 USD

Hi, i want to create a c sharp project to download multiple files with downloading bar progress.

the program will open a txt file and take the last number XXX.zip and start download xxx.zip+1 from URL till the file be out of loop(not exist).
StreamReader reader = new StreamReader(Directory.GetCurrentDirectory() + "\\example.txt");
var x = File.ReadAllLines("example.txt").Last();
and start to download the xxx.zip files
example (string url = "http://url/version/" + z + ".zip";)

Please use any other function instead of WebClient(); because it cant download multiple files and have to do sleep.
