HttpWebRespone 获取图片只有一半的问题

[yren]

下面的程序在下载网页上的一张17K 的照片，却只有下载了8K,请高手指教。
public byte[] GetHtml(Uri myUri)
{
byte[] mybuffer=new byte[38192];

HttpWebRequest myHttpWebRequest=(HttpWebRequest)WebRequest.Create(myUri);

HttpWebResponse myHttpWebResponse=(HttpWebResponse)myHttpWebRequest.GetResponse();

Stream myResponseStream=myHttpWebResponse.GetResponseStream;

int length=myResponseStream.Read(mybuffer,0,mybuffer.Length);

byte[] blob=new byte[length];
for(int i=0;i<length;i++)
{
blob[i]=mybuffer[i];
}

return blob;
}

我用两行

byte[] GetHttpFile(string url)
{
WebClient w = new WebClient();
return w.DownloadData(url);
}

要用HttpWebRespone类，因为会用到Cookies

[sdd330]

private string DownLoad(){
HttpWebRequest oRequest = (HttpWebRequest)WebRequest.Create(m_Url);
oRequest.Timeout = 1800000;
HttpWebResponse oResponse = (HttpWebResponse)oRequest.GetResponse();
StreamReader sr = new StreamReader(oResponse.GetResponseStream(), System.Text.Encoding.GetEncoding("GB2312"));
m_Contents = sr.ReadToEnd();
sr.Close();
oResponse.Close();
return Contents;
}

下载的是一张17K 的照片 必须return byte[]
