C# 在HTTP客户端中使用公共代理服务器

我正在尝试使用公共代理服务器(http://www.unblockwebnow.info/)要向目标站点发送HTTP请求，请说：）

我的HTTP客户端具有以下体系结构：

string url = "http://stackoverflow.com";
HttpWebRequest HttpWRequest = (HttpWebRequest)WebRequest.Create(url);
HttpWRequest.Method = "GET";

WebProxy myProxy = new WebProxy();
myProxy.Address = new Uri("http://www.unblockwebnow.info/");
HttpWRequest.Proxy = myProxy;

HttpWebResponse HttpWResponse = (HttpWebResponse)HttpWRequest.GetResponse();
StreamReader sr = new StreamReader(HttpWResponse.GetResponseStream(), encoding);
var rawHTML = sr.ReadToEnd();
sr.Close();

执行rawHTML的代码后，我得到了“pageok-由puppet管理-hostingcms02 pageok”

---

如果我注释掉

HttpWRequest.Proxy=myProxy行，我获取站点内容。
这似乎有效，但不适用于您的代理（不知道unblockwebnow.info的端口号）。
在URI中的“：”之后添加了端口号

代理地址乱七八糟。看起来像一个垃圾网站。如果它不能与他的代理一起工作，那么这并不能回答他的问题。
