How to get existing exchange binding from a queue?

[joe-agent]

We have an existing queue called QueueA with a binding of ExchangeA

Now we need to remove the binding of ExchangeA from QueueA by calling QueueUnbind method

How do we get the current binding exchange name from QueueA?
Is there any public method with example available?
Thanks

Bindings do not have any kind of ID, so queue.unbind uses a combination of source name (exchange name), destination name (in this case, queue name), routing key and (rarely used) optional binding arguments.

@michaelklishin , yes but the code where I call queue.unbind does not know what the exchange name is.

Is there any API method I can use from rabbitmq-dotnet-client to get all the existing exchange names bound to the queue name?

Then you cannot unbind that queue. Bindings do not have IDs, all operations on them are performed using source and destination names.

@joe-agent you can use the HTTP API to get queue binding information:
