Here\'s the code I have:

HttpWebRequest request = (HttpWebRequest)W         


        

Answer 1

Why not use the WebClient class?

using (WebClient webClient = new WebClient())
{
    webClient.DownloadFile("url", "filePath");
}

Answer 2

Your question asks about WebClient but your code shows you using Raw HTTP Requests & Resposnses.

Why don't you actually use the System.Net.WebClient ?

using(System.Net.WebClient wc = new WebClient()) 
{
    wc.DownloadFile("http://www.site.com/file.pdf",  "C:\\Temp\\File.pdf");
}

        private void Form1_Load(object sender, EventArgs e)
        {
  
            WebClient webClient = new WebClient();
            webClient.DownloadFileCompleted += new AsyncCompletedEventHandler(Completed);
            webClient.DownloadProgressChanged += new DownloadProgressChangedEventHandler(ProgressChanged);
            webClient.DownloadFileAsync(new Uri("https://www.colorado.gov/pacific/sites/default/files/Income1.pdf"), @"output/" + DateTime.Now.Ticks ("")+ ".pdf", FileMode.Create);
        }

        private void ProgressChanged(object sender, DownloadProgressChangedEventArgs e)
        {
            progressBar = e.ProgressPercentage;
        }

        private void Completed(object sender, AsyncCompletedEventArgs e)
        {
            MessageBox.Show("Download completed!");
        }
    }
}

Answer 4

Skip the BinaryReader and BinaryWriter and just copy the input stream to the output FileStream. Briefly

var fileName = "output/" + date.ToString("yyyy-MM-dd") + ".pdf";
using (var stream = File.Create(fileName))
  resp.GetResponseStream().CopyTo(stream);
