title: How to receive from IoT Hub the all messages a specific device sent?
body: <p>The code sends a message to the IoT Hub which stores the message in a BLOB storage.</p>
  
  <pre><code>_device = DeviceClient.Create(_iotHubUri, new 
  DeviceAuthenticationWithRegistrySymmetricKey(_deviceId, _deviceKey), 
  TransportType.Amqp_Tcp_Only);
  
  await _device.OpenAsync();
  
  await _device.SendEventAsync(message);
  </code></pre>
  
  <p>I see the message in the Azure portal. </p>
  
  <p>What I do not understand is how to get <strong>the all messages</strong> (C#) from the IoT Hub the device has sent?</p>
