Dear All:

I have a rather simple question:

#light

open System

let calcSearch (day:System.DateTime) =

match day.Day with

| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 -> day.Month

| 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 -> (day.Month * 10)

+ 1

| 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 -> (day.Month * 10)

+ 2

| _ -> (day.Month * 10)

+ 3

let dayToday = System.DateTime.Today

let monthSearch = calcSearch dayToday

let strSearch = monthSearch.ToString;;

When I run it in F# interactive, I got the error message:

monthSearch.ToString;;

^^^^^^^^^^^^^^^^^^^^

stdin(39,1): error FS0041: No overloads match for

method 'ToString'. Possible matches are shown below (or in the Error List

window).

Possible overload: 'Object.ToString() : string'.

Possible overload: 'Int32.ToString(format: string)

: string'.

Possible overload: 'Int32.ToString(provider:

IFormatProvider) : string'.

Possible overload: 'Int32.ToString(format: string,

provider: IFormatProvider) : string'.

>

Let me know if I miss anything, do I have to add any reference?

Thanks and Happy New Year to all!

.

ToString is a method, not a property. Try using...

1
2

let strSearch = monthSearch.ToString()

Notice the parentheses. A method (or function) with no inputs is invoke with a Unit, which is given by () ... Make sense?

Hello, Paulmichael Blasucci:
Thank you very much for the code and explanation.
It works!
Happy New Year to you!
