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 could try this:

var result = mySequence.Select(item => item.SomeStatus == SomeConst)
                      .Distinct().Count() > 1 ? false : true;

Basically I select true or false for each value, get distinct to only get one of each, then count those.
