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);
}
MessageBox 只是为了测试它,问题是每次我到达这一行时:
String htmlCode = client.DownloadString("http://cdrs.globalpopsvoip.com/0000069/20091229/20091228_20091228.CDR");
我得到一个例外:
远程服务器返回错误:(401) Unauthorized。
我该如何解决?
