Question

How do I create and initialize an array in F# based on a given record type?
Suppose I want to create an Array of 100 record1 records.

e.g.

type record1 = {
  value1:string;
  value2:string
}

let myArray = Array.init 100 ?

But it appears the Array.init does not allow for this, is there a way to do this?

Edited to add:

Of course I could do something like this:

let myArray = [|for i in 0..99 -> { value1="x"; value2="y" }|]

This should do what you need. Hope it helps.

type record1 = {
  value1:string;
  value2:string
}

let myArray  = Array.init 100 (fun x -> {value1 = "x"; value2 = "y"})

or using Generics

let myArray  = Array.init<record1> 100 (fun x -> {value1 = "x"; value2 = "y"})
