How to fetch an existing Exchange or Queue in EasyNetQ?

I am using EasyNetQ and I am wondering how to fetch an existing IExchange and IQueue without subscribing beforehand?

In the IAdvanceBus I can only see:

• ExchangeDeclareAsync
• QueueDeclareAsync

But I am not sure really whether those will override an existing queue or exchange with the same name?

Also how can I be sure that that queue or exchange exist before trying to fetch / declare it?

I did not take measurements. This is just a wrapper around RabbitMQ HTTP API. The disadvantage of this method is that an user account with elevated rights is required (It may differ from your “runtime” user account from connection string).

Actually, I have not looked at the repo for a long time. Now I see that there are methods IAdvancedBus.QueueDeclarePassiveAsync / IAdvancedBus.ExchangeDeclarePassiveAsync which, according to its description, does just what you need.

ManagementClient is the way to go, thanks @sungam3r! I’m going to close this issue.
