The remote server returned an error: (401) Unauthorized
.net, c#, http-status-code-401
Solution
In my case `client.UseDefaultCredentials = true;` did the trick.
Problem
I'm trying to get the html code of certain webpage, I have a username and a password that are correct but i still can't get it to work, this is my code: ``` private void buttondownloadfile_Click(object sender, EventArgs e) { NetworkCredentials nc = new NetworkCredentials("?", "?", "http://cdrs.globalpopsvoip.com/0000069/20091229/20091228_20091228.CDR"); WebClient client = new WebClient(); client.Credentials = nc; String htmlCode = client.DownloadString("http://cdrs.globalpopsvoip.com/0000069/20091229/20091228_20091228.CDR"); MessageBox.Show(htmlCode); } ``` The MessageBox is just to test it, the problem is that every time I get to this line: ``` String htmlCode = client.DownloadString("http://cdrs.globalpopsvoip.com/0000069/20091229/20091228_20091228.CDR"); ``` I get an exception: The remote server returned an error: (401) Unauthorized. How do I fix this?
