请高手进来帮忙

程序如下：
class sqlAccess{
private static Stream receiveStream = null;
private static StreamReader readStream = null;
private static HttpWebResponse response = null;
private static HttpWebRequest request = null;

static void Main(String []args){
try{
request = (HttpWebRequest)WebRequest.Creat(args[0]);
response = (HttpWebResponse)request.GetResponse();
receiveStream = response.GetResponseStream();
Encoding encode = System.Text.Encoding.GetEncoding("gb2312");
readStream = new StreamReader(receiveStream, encode);
Console.WriteLine(readStream.ReadToEnd());
}catch(Exception e){
Console.WriteLine(e);
}finally{
if(readStream != null)
readStream.Close();
if(receiveStream != null)
receiveStream.Close();
if(response != null)
response.Close();
}
}
}
获取很多网页都没问题，但"http://www.s1338.com/app/member/"，又不发生异常，输出就是一段空白。我用JAVA去获取，一切正常。
请问是什么原因啊？
