C# HttpWebResponse如何获取response body的HEX格式的数据？

Question

        public static string Post(string url, string content)
        {
            string result = "";
            #region 添加Post 参数
            byte[] data = Encoding.UTF8.GetBytes(content);
            try
            {
                HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
                req.Method = "POST";
                req.KeepAlive = false;
                req.ContentType = "application/x-www-form-urlencoded";
                req.ContentLength = data.Length;

                Stream reqStream = req.GetRequestStream();
                reqStream.Write(data, 0, data.Length);
                reqStream.Close();

                #endregion

                HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
                Stream stream = resp.GetResponseStream();
                //获取响应内容
                using (StreamReader reader = new StreamReader(stream, Encoding.UTF8))
                {
                    result = reader.ReadToEnd();
                    req.Abort();
                }
                return result;

            }
            return "";
        }

请问这个代码如何修改得到HEX数据?

Answer 1

Stream stream = resp.GetResponseStream();和后面修改为

using (Stream stream = resp.GetResponseStream())
            {
                using (MemoryStream ms = new MemoryStream())
                {
                    Byte[] buffer = new Byte[1024];
                    int current = 0;
                    while ((current = stream.Read(buffer, 0, buffer.Length)) != 0)
                    {
                        ms.Write(buffer, 0, current);
                    }
                    return ms.ToArray();
                }
            }

返回值类型修改为byte[]
