Question about creating an array...
f#

What's the best way to create an array of, say, bytes, with a specific size? I'm looking for something akin to 

1

let response = new Array<byte>(1024) in ...

Thanks!

.

Posting here must have had a catalytic effect, as I figured it out already, using:

1
2

let resp = Array.create 1034 0uy in

Hi Tamerlin

1

let response :byte array= Array.create 1024 0uy;;

Hope this helps.

I just realised you don't need to infer the type. Thanks to type inference.

let response = Array.create 1024 0uy

Hello,
depending on the way you want to initialize elements of the array, you can use one of the following three functions:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15

 

// Initialize an array with the default value (zero or 'null')
// Note, you may need to use type annotations, because 
// it may be difficult for the compiler to figure out the type
let ar = (Array.zero_create 1024 : int[])

// Initialize an array with a constant value (1 in this case)
let ar = Array.create 1024 1

// Initialize an array using a function that generates
// a value for every element - in this sample we build an array
// with values [| 0; 2; 4; 6; 8; ...; 2046 |]
let ar = Array.init 1024 (fun n -> n*2)

Good timing! Thanks for the help, even though I figured it out while you were posting the response, apparently :)

I appreciate the effort nonetheless.
