从java服务器套接字接收C#客户端套接字中的数据时出错

我正在创建一个带有C#客户端套接字和Java服务器套接字的套接字连接。当我从客户端套接字发送数据时，服务器套接字正在正确地接收该数据。但是，当我试图将数据从服务器套接字发送回客户端套接字时，它在客户端接收数据时被挂起了。

客户端代码（在C#.net中）

           clientSocket = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);
            string hostName = System.Net.Dns.GetHostName();
            System.Net.IPHostEntry hostEntry = System.Net.Dns.GetHostEntry(hostName);
            System.Net.IPAddress[] ipAddresses = hostEntry.AddressList;
            System.Net.IPEndPoint remoteEP =
                new System.Net.IPEndPoint(ipAddresses[ipAddresses.Length - 1], port);
            clientSocket.Connect(remoteEP);
             string sendData = inputFilePath;
                    byte[] byteDataSend = System.Text.Encoding.ASCII.GetBytes(sendData);
                    clientSocket.Send(byteDataSend);
                    int receivedBufferSize = clientSocket.ReceiveBufferSize;
                    byte[] recivedData = new Byte[receivedBufferSize];
                    int receivedDataLength = clientSocket.Receive(recivedData);
                    string stringData = Encoding.ASCII.GetString(recivedData, 0, receivedDataLength);
                    textFilePath = stringData;
                    Console.Write(stringData);
                    clientSocket.Close();

服务器套接字代码（Java）

           Socket connection = server.accept();
            BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream())); 
            fileName = in.readLine();
            convertedFile =runConverter.convertDocumet(fileName);
            byte[] sendingData = convertedFile.getBytes("US-ASCII");
            DataOutputStream dos = new DataOutputStream(connection.getOutputStream());
            dos.write(sendingData, 0, sendingData.length);

告诉我问题出在哪里？？请帮忙。。。
