About partten matching
f#

let test ('a) () =

match typeof ('a) with

| x when x = typeof( int ) -> () //right way

| typeof( int ) -> () //error way

Why this " typeof( int ) > -> () " is error?

.

You don't have to use the typeof - function at all - just do something like

1
2
3
4
5
6
7
8
9
10
11

 

let test (t : obj) = 

   match t with

   | :? int -> () // ... its an integer 

   | :? string -> () // ... its an string 

   | _ -> () // ... whatever

To preempt a possible next question, you can bind to a variable like so:

1
2
3
4

let test (t : obj) = 
   match t with
   | :? int as x -> () // ... x is an integer 
   | :? string as x -> () // ... x is a string 
   | _ -> () // ... whatever
