Try to get short string for today.
f#

Dear All:
Happy New Year to you!
I want to have a short string for today, like: "2010-01-02".
In F# interactive, I tried this:
> open System
let dtmToday = System.DateTime.Today.ToShortDateString;;

val dtmToday : (unit -> string)

> dtmToday;;
val it : (unit -> string) = <fun:dtmToday@3>

But in SQL Server database, for a data field type as "Date", such binding works. I mean you can give a date type field a value as "System.DateTime.Today.ToShortDateString", but here it is not working.
Let me know how to get the string using not a lot of code.
Thanks,

.

ToShortDateString is an instance method of the DateTime class, which takes no parameters; as such, it should be applied with Unit...

let dtmToday = System.DateTime.Today.ToShortDateString ();;

Your code effectively creates a partial application via a closure. In other words, you could also write the following...

let dtmToday = System.DateTime.Today.ToShortDateString;;

printfn "%A" (dtmToday ())

This is exactly what FSI is telling you in the final line

val it : (unit -> string) = <fun:dtmToday@3>

If one is learning an ML-based language, its probably best for one to understand ML's rather specific type notation.

Also, off topic, what does CommunityServer discriminate against Mac users?

Hello, Paulmichael Blasucc:
Thank you very much for your code and explanation, now I understand it much better.
Thanks again!
