FirstOrDefault In F#

How to write FirstOrDefault Linq Query in F#? Can I use linq to sql in F# in totally?

Answer 1

Alternatively, you can define your own firstordefault easily:

let firstordefault list =
   match list with
   | head :: tail -> head 
   | [] -> 0 // some default value

Example:

let exampleList = [ 1; 2; 3 ]

using F# interactive,

firstordefault exampleList;;  
val it : int = 1
