The System.Int32.TryParse method has signature string * byref<int> -> bool (although F# allows you to use the method as if it returns a tuple). Quotations cannot contain uses of byref types, which unfortunately includes the implicit use in your code.
Thanks for the explanation!
There exists a workaround to overcome this problem and control the string format?

Built with WebSharper |
Hi everybody,
i need help because i don't understand what's wrong in this code:
let sum index = listValues |> List.map (fun value -> let (success, number) = Int32.TryParse(!value) number ) |> List.reduce (fun x y -> x + y)The build error (cited in the thread subject) is on line with the TryParse method.
Thanks a lot.
