当我使用我的代码获取网页时，我不断获取这些内容，但我可以使用 XMLhttp 和 VB 来获取整个页面，这是我的代码如下：

public static string GetPage(string Url)
{
HttpWebRequest WebRequest = (HttpWebRequest)HttpWebRequest.Create(Url);
WebRequest.Timeout = 5000;
WebRequest.AllowAutoRedirect = true;
WebRequest.Headers.Set("Pragma", "no-cache");

try
{
   using (HttpWebResponse response = (HttpWebResponse)WebRequest.GetResponse())
   {
      using (Stream stream = response.GetResponseStream())
      {
        using (StreamReader sr = new StreamReader(stream, Encoding.GetEncoding("UTF-8")))
           { return sr.ReadToEnd(); }
      }
   }
}
catch (Exception ex){ return "%ERROR%" + ex.Message; }
}
