分享如何取到http流的长度？
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
httpWebRequest.KeepAlive = false;
HttpWebResponse httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse();
Stream streamResponse=httpWebResponse.GetResponseStream();
BinaryReader binaryReader = new BinaryReader(streamResponse);
buffer = new byte[streamResponse.Length];
最后一行代码有问题！我该怎么取呢？我要建立一个缓冲区，byte[]类型的。
