关于网页内容抓取的问题

[dongyanming826]

大家好，我用如下方法抓网页，为什么时而能抓全时而不全啊

WebRequest request = WebRequest.Create("http://bbs.55bbs.com/thread-2428128-6-1.html");
WebResponse response = request.GetResponse();
//返回信息
Stream resStream = response.GetResponseStream();
StreamReader sr = new StreamReader(resStream, System.Text.Encoding.Default);
string tempCode = sr.ReadToEnd();
resStream.Close();
sr.Close();

StreamWriter sw = new StreamWriter("f:\\aaaa.txt", false, Encoding.GetEncoding("GB2312"));
sw.Write(tempCode);
sw.Flush();
sw.Close();
response.Close();

实在不知道是为什么，哪位帮我看下啊
