我实现了一个从websitl下载文件的方法..但我想修改它以显示进度条上的下载进度：

I implemented a method that download a file from a websitl ..but I want to modify it to desplay the download progress on progress bar:

 

public static void DownloadFile(string URL, string FileName, out string responseFromServ, out string StatusDesc)
  {
   // Create a request for the URL. 
   WebRequest request = WebRequest.Create(URL+"/"+FileName);
   // Get the response.
   WebResponse response = request.GetResponse();
   // Display the status.
   StatusDesc = ((HttpWebResponse)response).StatusDescription;
   // Get the stream containing content returned by the server.
   Stream dataStream = response.GetResponseStream();
   // Open the stream using a StreamReader for easy access.
   StreamReader reader = new StreamReader(dataStream);
   // Read the content.
   responseFromServ = reader.ReadToEnd();
   // Clean up the streams and the response.
   reader.Close();
   response.Close();
  }
