I'm new to F#. I'm using VS2008 shell and F# interactive. I try to split a string using "System.String.Split" but then I get the error: "Split is not a static method"
code example:
let Count text =
let words = System.String.Split [' '] text
let nWords = words.Length
(nWords)
How do I use the String methods like split in F# ?
You call them as instance methods:
let Count (text : string) =
let words = text.Split [|' '|]
let nWords = words.Length
(nWords)
(Note you need to use [| |] because Split takes an array not a list; or, as per Joel Mueller's comment, because Split takes a params array, you can just pass in the delimiters as separate arguments (e.g. text.Split(' ', '\n')).)
The function String.split is now defined in the F# Power Pack. You must add
#r "FSharp.PowerPack.dll";;
#r "FSharp.PowerPack.Compatibility.dll";;
