Piping a list into the line in F#

Question

Now I can add single value or tubles to the pipeline, my next question is can I add a list/array:

filesUnderFolder
|> Seq.map FileInfo  

my problem is I can't process this with pipeline |>, or can I?

Assembly.GetExecutingAssembly.GetFiles()
|>Array.map (fun file -> file.ReadAllText().Contains(keyword))

Answer 1

Looking at your comment are you trying to do this?

Assembly.GetExecutingAssembly().GetFiles() 
|> Seq.map (fun file -> 
    let stream = new StreamReader(file)
    file, stream.ReadToEnd().Contains(keyword))
|> Seq.filter snd
|> Seq.map fst
|> Seq.iter (fun file -> printfn "%s" file.Name)

Imperative style can be cleaner.

for file in Assembly.GetExecutingAssembly().GetFiles() do
    let stream = new StreamReader(file)
    if stream.ReadToEnd().Contains(keyword) then
        printfn "%s" file.Name
