我试图让我的程序通过代理工作，但它不想（System.Net.WebException：操作已超时）。没有代理一切都很好

这是一个代码：

        string proxy = "154.46.33.157";
        int port = 8080;
        ASCIIEncoding encoding = new ASCIIEncoding();
        string postData = "email=" + email + "&pass=" + pass;
        byte[] data = encoding.GetBytes(postData);
        WebProxy myproxy = new WebProxy(proxy, port);
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create("SITE");
        WebHeaderCollection myWebHeaderCollection = request.Headers;
        request.CookieContainer = sCookie;
        request.Method = "POST";
        request.Proxy = myproxy;
        request.ContentType = "application/x-www-form-urlencoded; charset=UTF-8";
        request.ContentLength = data.Length;
        request.Host = "HOST";
        request.UserAgent = "[UA]";
        request.Referer = "reffer";
        request.KeepAlive = false;
        request.Timeout = 20000;

        Stream stream = request.GetRequestStream(); // TIMEOUT HERE
        stream.Write(data, 0, data.Length);
        stream.Close();
        request.GetResponse()
            .Close();

同时这段代码运行良好

        string proxy = "154.46.33.157";
        int port = 8080;
        WebProxy myproxy = new WebProxy(proxy, port);
        WebRequest req = WebRequest.Create("SITE");
        req.Timeout = 5000;
        req.GetResponse();

代理还活着，我已经通过 IE 对其进行了测试。我应该怎么做才能解决它？

尝试将以下内容添加到您的web.config或app.config取决于应用程序类型：

<configuration>

    <system.net>
        <defaultProxy>
            <proxy
                usesystemdefaults="true"
                proxyaddress="http://154.46.33.157:8080"
                bypassonlocal="true" />
              <bypasslist
                <add address="[a-z]+\.contoso\.com" />
            </bypasslist>
        </defaultProxy>
    </system.net>          

     <!-- The rest of your config here ... -->

</configuration>

几点建议：

  1. 您是否使用 IP 地址作为代理？
  2. 您需要登录该代理吗？proxy.Credentials = new NetworkCredential（用户，密码）；
  3. 尝试更少的标题，从少数开始，如果有效，请继续一一添加

UPD：对于主机 - 它是有效的 URL 吗？你输入了一个有效的端口号吗？像 www.contoso.com:8080
