LINQ identity function?

Question

Just a little niggle about LINQ syntax. I\'m flattening an IEnumerable> with SelectMany(x => x).

My problem i

Answer 1

I'd go with a simple class with a single static property and add as many as required down the line

    internal class IdentityFunction
    {
        public static Func Instance
        {
            get { return x => x; }
        }
    }

    SelectMany(IdentityFunction.Instance)
