Here you're doing some very imperative things like writing a statement rather than an expression (as presumably the Each method returns no value) and mutating state (which one can only assume the methods do, as they also appear to return no value) yet you're trying to pass them off as 'functional programming' by passing a collection of statements as a delegate. This code could barely be further from the ideals and idioms of functional programming, so why try to disguise it as such?
As much as I like multi-paradigm languages such as C#, I think they are easiest to understand and maintain when paradigms are mixed at a higher level (e.g. an entire method written in either a functional or an imperative style) rather than when multiple paradigms are mixed within a single statement or expression.
If you're writing imperative code just be honest about it and use a loop. It's nothing to be ashamed of. Imperative code is not an inherently bad thing.
