求救~socket自定义TCP传输文件，只能接收4M内容，后面的数据库包获取不到啊

求救~socket 文件接收只能获得4M内容，后面的数据库包获取不到啊.

我捣鼓这个问题弄了一个星期了，实在搞不明白。真是没办法了，所以推上首页问问。阿弥陀佛

这是两个方法：

        /// <summary>

        /// 获取标示

        /// </summary>

        /// <param name="s"></param>

        /// <returns></returns>

        private static byte[] ReceiveVarFlag(Socket s)

        {

            int recv;

            byte[] datasize = new byte[4];

            recv = s.Receive(datasize, 0, 4, SocketFlags.None);

            return datasize;

        }



        /// <summary>

        /// 按照长度获取内容

        /// </summary>

        /// <param name="s"></param>

        /// <returns></returns>

        private static byte[] ReceiveVarContent(Socket s,int len)

        {

            int recv;

            byte[] datasize = new byte[len];

            recv = s.Receive(datasize, 0, len, SocketFlags.None);

            return datasize;

        }

这是main函数：

static string filesfolder = "c:\\xxx\\";

        static void Main(string[] args)

        {

  

            int port = 12345;

            //string hostip = "127.0.0.1";

            //IPAddress ip = IPAddress.Parse(hostip);

            IPEndPoint ipe = new IPEndPoint(IPAddress.Any, port);

            Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

            s.Bind(ipe);

            s.Listen(0);

            Console.WriteLine("Waitforconnect");

            while (true)

            {

                int packsiez = 4;

                Socket temp = s.Accept();

                byte[] biaoshi = new byte[4];

                byte[] nssid = new byte[4];

                byte[] urllen = new byte[4];

               

                byte[] filelen = new byte[4];

                

                //------------



                //------------



                biaoshi = ReceiveVarFlag(temp);

                nssid = ReceiveVarFlag(temp);

                urllen = ReceiveVarFlag(temp);

                int _urllen = BitConverter.ToInt32(urllen, 0);

                byte[] urlcontent = new byte[_urllen];

                urlcontent = ReceiveVarContent(temp, _urllen);

                filelen = ReceiveVarFlag(temp);



                int _biaoshi = BitConverter.ToInt32(biaoshi, 0);

                int _nssid = BitConverter.ToInt32(nssid, 0);

                string _urlcontent = Encoding.Default.GetString(urlcontent);

                Random r = new Random();

                string filename = DateTime.Now.ToString("yyyyMMddHHmmss") + r.Next();

                





                int _filelen = BitConverter.ToInt32(filelen, 0);



                int rescount = _filelen / packsiez;

                int lastpacksizi = _filelen % packsiez;

                if (lastpacksizi!=0)

                {

                    rescount++;

                }

                string SendFileName = filesfolder + filename + ".rar";

                int wcount=0;

                using (FileStream MyFileStream = new FileStream(SendFileName, FileMode.Create, FileAccess.Write))

                {

                    for (int i = 0; i <rescount; i++)

                    {

                        if (temp.Connected)

                        {

                            if (i==rescount-1)

                            {

                                packsiez = lastpacksizi;

                            }

                            byte[] t=new byte[packsiez];

                            int counts= temp.Receive(t, 0, packsiez, SocketFlags.None);

                            if (counts==0)

                            {

                                break;

                            }

                            MyFileStream.Write(t, 0, packsiez);

                            wcount+=packsiez;

                            t = null;

                        }

                        else

                        {

                            break;

                        }

                    }

                }

                Console.WriteLine("-----------------------------------------------");

                Console.WriteLine("包总长:" + _filelen.ToString() +"保存:" + wcount );

                Console.WriteLine("文件内容写入:" + SendFileName);

                WriteInfos(_biaoshi, _nssid, _urllen, _urlcontent, filename);        //写入日志信息

        

            }

        }

我每次大概只能获得4100KB的东西。

如果不退出，继续获取，那么获得的全是空。最后用UE看文件，文件大小是对上了，但是后半截内容全是0x00
