Answer 1

Are you sure that you're using Where and not Select?

Using Where will return an IEnumerable<string> which is what you're expecting.

Using Select will return an IEnumerable<bool> which is what you say is actually happening.

Here is the answer...

foreach (var key in collection.AllKeys.Where(k => !k.Contains("Pricing")).ToArray<string>()){ ... }
