Question

请协助以下代码。

当我在不需要代理的Pc上使用它并且代理设置被注释掉它工作正常但现在我必须在启用代理的网络上运行该程序，但它不断给我错误：

发生了'System.Net.WebException'类型的未处理异常 System.dll附加信息：远程服务器返回了一个错误：（407）需要代理验证。

请注意，如果您尝试运行该程序，它将无法获取数据，因为它需要从IP列在白名单上的PC上运行。

确保您的代理详细信息正确无误并向 WebProxy 对象提供凭据

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(urlDemo);
request.Credentials = new NetworkCredential("matt.luck", "Mambo88e","JOC");
WebProxy aProxy = new WebProxy();
aProxy.Address = new Uri("Http://182.155.1.205:8080",true)
aProxy.Credentials = new NetworkCredential("matt.luck", "Mambo88e","JOC");
