How to neatly query corresponding object array items?

Question

I have an array of objects that\'ll be used for some process.

var x = new List() { new MyObject(), new MyObject(), ... }.ToArray();

Answer 1

Well, you can use Zip to pair them up:

var pairs = x.Zip(y, (a, b) => new { a, b })
             .Where(pair => !pair.b.IsOkay)
             .ToArray();

You can change the delegate passed to Zip to compose the two values differently if you want - for example, using a named type instead of the anonymous type I've got above.
