站点间传送文件不匹配

需求是要在A站点中传送ZIP包到B站点中去。
可是传送的文件无法匹配。连大小都不一样。接收到的总是小。

A站点代码：



                //fileName为文件路径

                FileInfo zipFile = new FileInfo(fileName);



                FileStream r = zipFile.OpenRead();



                context.Response.Buffer = false;

                context.Response.HeaderEncoding = Encoding.Default;

                context.Response.ContentEncoding = Encoding.Default;

                context.Response.AddHeader("Connection", "Keep-Alive");

                context.Response.ContentType = "application/octet-stream";

                context.Response.AddHeader("Content-Disposition", "attachment;filename=" + System.IO.Path.GetFileName(HttpUtility.UrlEncode(tempUrl.Replace("/", "") + ".zip", Encoding.Default))); // 此处文件名如果是中文在浏览器默认是筹码,应该加HttpUtility.UrlEncode(filename) 

                context.Response.AddHeader("Content-Length", r.Length.ToString());



                while (true)    //如果文件大于缓冲区，通过while循环多次加载文件 

                {

                    //开辟缓冲区空间   

                    byte[] buffer = new byte[1024];  //读取文件的数据   

                    int leng = r.Read(buffer, 0, 1024);

                    if (leng == 0)//到文件尾，结束 

                    {

                        break;

                    }

                    if (leng == 1024)//读出的文件数据长度等于缓冲区长度，直接将缓冲区数据写入 

                    {

                        context.Response.BinaryWrite(buffer);//向客户端发送数据流 

                    }

                    else

                    {

                        //读出文件数据比缓冲区小，重新定义缓冲区大小，只用于读取文件的最后一个数据块  

                        byte[] b = new byte[leng]; for (int i = 0; i < leng; i++)

                            b[i] = buffer[i];

                        context.Response.BinaryWrite(b);

                    }

                }

                r.Flush();

                r.Close();//关闭下载文件  

                //context.Response.End();//结束文件下载

B站点代码：

//url为A站对应handler地址，postData为参数

            string result = ValuePageHelper.Post(url, postData);



            string savePath = (context.Server.MapPath(StringHelper.Remove(tempUrl, "/") + ".zip"));





            if (File.Exists(savePath))

            {

                File.Delete(savePath);

            }



            //File.Create(savePath);



            MemoryStream memoryStream = new MemoryStream(Encoding.Default.GetBytes(result));



            FileStream zipFile = new FileStream(savePath, FileMode.Create);



            memoryStream.WriteTo(zipFile);



            memoryStream.Close();



            zipFile.Close();



            memoryStream = null;



            zipFile = null;



 /// <summary>

        /// 后台Post提交

        /// </summary>

        /// <param name="url">要提交的URL</param>

        /// <param name="postData">request传递格式.Example:a=1&b=2</param>

        /// <returns></returns>

        public static string Post(string url, string postData)

        {

            try

            {

                byte[] byteArray = Encoding.Default.GetBytes(postData);

                HttpWebRequest objWebRequest = (HttpWebRequest)WebRequest.Create(url); //发送地址

                objWebRequest.Method = "POST";//提交方式

                objWebRequest.ContentType = "application/x-www-form-urlencoded";

                objWebRequest.ContentLength = byteArray.Length;

                Stream newStream = objWebRequest.GetRequestStream(); // Send the data.

                newStream.Write(byteArray, 0, byteArray.Length); //写入参数

                newStream.Close();

                HttpWebResponse response = (HttpWebResponse)objWebRequest.GetResponse();

                //获取响应

                StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.Default);

                return sr.ReadToEnd(); // 返回的数据



            }

            catch (Exception)

            {

                return "false";

            }

        }
