How can I reuse expressions with WhenAny

[Martin H. Andersen]

I have this:

var canAddSimpleControl = this.WhenAny(x => x.SelectedItem, x => x.SelectedItem.Children.Count, (i, c) => i.Value != null && CanAddNoneContainerControl);

I want to reuse this

var reuse = (x => x.SelectedItem, x => x.SelectedItem.Children.Count, (i, c) => i.Value != null

So I can write 

var canAddSimpleControl = this.WhenAny(reuse && CanAddNoneContainerControl);

How about:

var reuse = this.WhenAny(x => x.SelectedItem, x => x.SelectedItem.Children.Count, (i, c) => i.Value != null);
canAddSimpleControl = reuse.Where(x => CanAddNoneContainerControl());
