f＃异常在循环中引发

Question

Is there a reason why the exception is displayed before the function has even started in the following?

let listCharacters (text:string) =
    let stripv3 =  text.Split([|' '|], System.StringSplitOptions.RemoveEmptyEntries) |> System.String.Concat      

    for i in 0..2..stripv3.Length do
            let char = stripv3.Chars(i)
            if char <> ' ' then
                printfn "%c" char  

listCharacters "honey badger is a badass"

Produces the following output:-

System.IndexOutOfRangeException: Index was outside the bounds of the array.
h
n
y
a
g
r
s
b
d
s

Interestingly if I add a try..with any operations within the with occurs in order, any ideas why this is?

Answer 1

To summarise the comments above the problem is specific to the IDE and not to the language.

In this instance the issue was only seen in the Visual Studio F# Interactive view.

When executed fully or run via Visual Studio FSI.exe the exception was the last item to be output.
