Question

I want the last character from a string

I’ve got str.[str.Length - 1], but that’s ugly. There must be a better way.

Answer 1

There’s no better way to do it – what you have is fine.

If you really plan to do it a lot, you can author an F# extension property on the string type:

let s = "food"

type System.String with
    member this.Last =
        this.Chars(this.Length-1)  // may raise an exception

printfn "%c" s.Last
