Is there a better way of calling LINQ Any + NOT All?

Question

I need to check if a sequence has any items satisfying some condition but at the same time NOT all items satisfying the same condition.

For example, for a sequence of 10

Answer 1

You can use the Aggregate method to do both things at once. I would suggest to use an anonymous type for the TAccumulate, containing both counters. After the aggregation you can read both values from the resulting anonymous type.

(I can't type an example, I'm on my phone)
