Question

In F#, I am parsing a decimal string with

let foo str =
    match Decimal.TryParse str with
    | (true, result) -> Some result
    | (false, _) -> None

which uses the current system culture to parse the string. But I actually want to parse the string using CultureInfo.InvariantCulture. Can this be done in a pattern matching manner like above? If not, what is the cleanest way to do this?

Use something like:

 let foo str =
     match System.Decimal.TryParse(str, NumberStyles.AllowDecimalPoint, CultureInfo.InvariantCulture) with
     | (true, result) -> Some result
     | (false, _) -> None
