The part you're looking for is Where and not Select.

var a = Straight.Where(o => (o % 4) == 0).ToArray();

Select projects your list into a new returns type which in the case of the expression (o%4) == 0 is boolean.

Where returns you the same object that fulfill the desired expression.

You need Where, not Select

var a = Straight.Where(o => o % 4 == 0).ToArray();

Select creates a projection. In your example, it turns each element of Straight into a bool.
