c# - 下载文件时出现 401 网络异常

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");

每次，我都会收到此网络异常

远程服务器返回错误：(401) Unauthorized。

有什么线索吗？

Answer 1

我建议始终保持简单。尝试这个

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