关于 GetHttp 以及System.IO.Stream

C# code

        public static List<int> GetHttp (string httpUrl)        {            List<int> result = new List<int>();             HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create (httpUrl);            myReq.Method = "GET";            try            {                                HttpWebResponse HttpWResp = (HttpWebResponse)myReq.GetResponse ();                System.IO.Stream myStream = HttpWResp.GetResponseStream ();                int data = -1;                while ((data = myStream.ReadByte()) != -1)                {                    // 因为不清楚 myStream.Length 是否真实字节流长度. 所以用了动态数组List                    result.Add(data);                }            }            catch (Exception exp)            {                Debug.Log(exp.ToString());            }            return result ;         }

所以疑问: myStream.Length 获得的是真实长度吗? 其实我就是想获得 byte[] 返回值

[解决办法]
真实字节流长度应该通过response.ContentLength获取，我之前测试过，直接使用ResponseStream的Length会报错的，另外你每次只读一个字节，效率很差的
