I am reading a file into an array like follows (note I know this is bad code):
let filename = if argv.[0] != null then argv.[0] else System.Console.ReadLine()
let data = File.ReadAllLines(filename)
I want to perform an F# map
onto the data returned in that above line. My problem is that I can only perform map
on n F# list, and not the System.String[]
that File.ReadAllLines()
returns. Can I convert a standard .Net array into an F# list. I'm sure that I could just read the file differently, or labor through manually copying the array contents to a list, but it would be a lot easier if there was a simple way to do this.
This sound is usually considered to be an allophone of /h/, which is pronounced in different ways depending upon its context; Japanese /h/ is pronounced as [ɸ] before /u/. In Welsh orthography, ⟨f⟩ represents /v/ while ⟨ff⟩ represents /f/. In Slavic languages, ⟨f⟩ is used primarily in words of foreign (Greek, Latin, or Germanic) origin.
In countries such as the United States, the letter "F" is defined as a failure in terms of academic evaluation. Other countries that use this system include Saudi Arabia, Venezuela, and the Netherlands. In the hexadecimal number system, the letter "F" or "f" is used to represent the hexadecimal digit fifteen (equivalent to 15 10 ).
In the Etruscan alphabet, 'F' probably represented /w/, as in Greek, and the Etruscans formed the digraph 'FH' to represent /f/.
It is often doubled at the end of words. Exceptionally, it represents the voiced labiodental fricative / v / in the common word "of". F is the twelfth least frequently used letter in the English language (after C, G, Y, P, B, V, K, J, X, Q, and Z ), with a frequency of about 2.23% in words.
You can use Array.toList
to do that.
let data2 = data |> Array.toList
Or you can use List.ofArray
let data2 = data |> List.ofArray
You can also do Array.map
instead of List.map
and in that case you might not need to map to list
at all.
