f# - How to project (transform) an array of FileInfo to a list of strings with fsharp -

what trying this:

let getfiles path =  (directoryinfo path).getfiles().tolist

but gives me list of fileinfos instead of list of strings. how can project list of strings?

thx in advance

assuming want paths associated each file can do:

let getfiles path = (directoryinfo path).getfiles() |> array.map (fun fi -> fi.fullname) |> list.ofseq

note creates f# list, not system.collections.generic.list<string>. if want create 1 of these can use resizearray:

let getfiles path = (directoryinfo path).getfiles() |> array.map (fun fi -> fi.fullname) |> (fun s -> resizearray<_>(s))

edit: comment points out, since getfiles returns array, can use array.map , avoid converting list/resize array if don't need it.
