感谢指出。我看到通过实现.same结果，但后来又看了一个评论谁说使用IE引擎我转过来并做了一个小应用程序完成工作。我添加了IE并导航到网站并阅读内容这是代码

  private void webBrowser1_DocumentCompleted(object sender, System.Windows.Forms.WebBrowserDocumentCompletedEventArgs e) { System.Windows.Forms.HtmlElementCollection elementsforViewPost = webBrowser1.Document.GetElementsByTagName("font"); foreach (System.Windows.Forms.HtmlElement current2 in elementsforViewPost) { if (current2.InnerText != null && CheckForValidProxyAddress(current2.InnerText) && ObtainedProxies.Where(index=>index.ProxyAddress == current2.InnerText.Trim()).ToList().Count == 0) { Proxy data = new Proxy(); data.IsRetired = false; data.IsActive = true; int result = 1; data.DomainsVisited = 0; data.ProxyAddress = current2.InnerText.Trim(); ObtainedProxies.Add(data); } 

并且为了检查收到的文本是否有效代理，这是我很久以前通过谷歌搜索从一些页面获得它

  private bool CheckForValidProxyAddress(string address) { //create our match pattern //string pattern = @"^([1-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])(.([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])){3}$:([0-9][0-9][0-9][0-9])"; string pattern = @"b(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)b:[0-9]{0,4}"; //create our Regular Expression object Regex check = new Regex(pattern); //boolean variable to hold the status bool valid = false; //check to make sure an ip address was provided if (address == "") { //no address provided so return false valid = false; } else { //address provided so use the IsMatch Method //of the Regular Expression object valid = check.IsMatch(address, 0); } //return the results return valid; } 

我认为你不得不以某种方式使用IE引擎。
