How do I Moq It.IsAny for an array in the setup of a method?

I'm brand new to Moq (using v 4) and am struggling a little with the documentation. What I'm trying to do is to Moq a method that takes a byte array and returns an object. Something like: ``` decoderMock.Setup(d => d.Decode(????).Returns(() => tagMock.Object); ``` The ???? is where the byte[] should be, but I can't work out how to make it so that I don't care what's in the byte array, just return the mocked object I've already set up. Moq.It.IsAny expects a generic. Any help please?
