下载文件时出现401 Web异常

Question

我想从网站下载某个文件。为此，我尝试使用这个

WebProxy p = new WebProxy("192.168.10.254:8080", true);
p.Credentials = new NetworkCredential("username", "pwd");
WebRequest.DefaultWebProxy = p;
WebClient client = new WebClient();
string downloadString = client.DownloadString("myDowloadUrl");

每一次，我都会遇到此网络异常

  

远程服务器返回错误：（401）未经授权。

任何线索？

Answer 1

我建议一直保持简单。试试这个

       using (var Client = new WebClient())
        {
            Client.Credentials = new System.Net.NetworkCredential("username", "pwd");
            Client.DownloadFile("myDowloadUrl", @"downloadFilelocalpath");
        }
