我正在尝试获取某个网页的 html 代码，我有一个正确的用户名和密码，但我仍然无法让它工作，这是我的代码：
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);
}

I have tried the following code and it is working.
我已经尝试了以下代码并且它正在工作。
private void Form1_Load(object sender, EventArgs e)
{
try
{
// Create Request
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(@"http://192.168.0.181/axis-cgi/com/ptz.cgi?move=up");
// Create Client
WebClient client = new WebClient();
// Assign Credentials
client.Credentials = new NetworkCredential("root", "a");
// Grab Data
string htmlCode = client.DownloadString(@"http://192.160.0.1/axis-cgi/com/ptz.cgi?move=up");
// Display Data
MessageBox.Show(htmlCode);
}
catch (WebException ex)
{
MessageBox.Show(ex.ToString());
}
}

In my case client.UseDefaultCredentials = true;did the trick.
在我的情况下client.UseDefaultCredentials = true;成功了。
