Linq Detect Non Zero GUIDs in an array?

I am having a brain freeze. I have an array of n GUIDs and either all of them will have complete zeros, or they all won't. I am trying to come 开发者_Python百科up with a succinct Linq query that will be true or false if they all contain "00000000-0000-0000-0000-000000000000" but can't, so here I am. Can anyone help?

Thanks.

Like this:

if (arr.Any(g => g != Guid.Empty))

How about:

IEnumerable<Guid> guids = ...    
bool allZeros = guids.All(guid => guid == Guid.Empty);

---

You can use:

bool allZero = array.All(guid => guid == Guid.Empty);

What about checking for Guid.Empty? It is equal to a Guid with all zeroes.
