[Question] How to create a ByteBuffer from an array of bytes?

Hi everyone 👋,

I’m having some trouble getting an instance of Amqp.Message when receiving a message from a AMQP broker (RabbitMQ in this case). All I have in the receiving end is an array of bytes, here is a code snippet:

byte[] body = //something...
Amqp.Message message = Amqp.Message.Decode(new ByteBuffer(body, 0, body.Length, body.Length));

This results in this error: System.InvalidOperationException: 'buffer too small'.

I’ve also tried doing Message.Decode(new ByteBuffer(body, 0, 0, body.Length)) instead, but I get a System.NullReferenceException in another line of code since all fields in the Amqp.Message are null. For further context on my use case, I’m using CloudNative.CloudEvents and CloudNative.CloudEvents.Amqp which uses AMQP.Net Lite, so I’m trying to get an Amqp.Message in order to get a CloudEvent instance: CloudEvent decodedMessage = message.ToCloudEvent(new JsonEventFormatter());

Any help is much appreciated, Thank you!

That is fine if it is not too much work for you. Since you have it in code, you could also encode it as BASE64 string and post the string here.

@xinchen10 thank you, it works with ReadOnlyMemory 👍. Not sure why it wasn’t working with the snippet I sent before for decoding, but your explanation makes sense. I’ll close this issue since it’s now resolved, thanks again for all the help 😃
