无限循环读取字节Xamarin Android蓝牙

Question

我正在做一个Xamarin Android应用，我的目标是在两个设备之间发送数据。我的代码基于官方蓝牙聊天

https://developer.xamarin.com/samples/monodroid/BluetoothChat/

现在我想发送文件，所以我修改了Run()类的ConnectedThread方法以接收大量字节，以模拟文件。

以下是代码：

const string TAG = "ConnectedThread";
private BluetoothSocket _socket;
Stream inStream;
Stream outStream;
private BluetoothTransactionService _service;

        public override void Run()
                {
                    Log.Info(TAG, "BEGIN mConnectedThread");
                    byte[] buffer = new byte[10240];
                    int bytes;

                    // Keep listening to the InputStream while connected
                    while (_service.GetState() == BluetoothTransactionService.STATE_CONNECTED)
                    {
                        try
                        {
                            // Read from the InputStream
                            MemoryStream memoryStream = new MemoryStream(2048);
    // Here is the bug.
                            while((bytes = inStream.Read(buffer,0, buffer.Length) ) > 0)
                            {
                                memoryStream.Write(buffer, 0, bytes);
                            }

                            buffer = memoryStream.ToArray();

                            // Send the obtained bytes to the UI Activity
                            _service._handler
                                    .ObtainMessage(BluetoothConstants.MESSAGE_READ, buffer.Length, -1, buffer)
                                   .SendToTarget();
                        }
                        catch (Java.IO.IOException e)
                        {
                            Log.Error(TAG, "disconnected", e);
                            _service.ConnectionLost();
                            break;
                        }
                    }
                }

输入流的inStream.Read方法正在等待数据，而while循环永远不会被破坏，我不明白为什么。对我来说，while循环将会中断，因为没有更多的数据可供阅读。

感谢您的帮助。
