Initialize and assign values to list of ints without a loop

is there a shorter way to do t开发者_StackOverflowhis:

        List<int> mins = new List<int>();
        for(int i = 0; i<60; i++)
        {
            mins.Add(i+1);
        }

Functional version also appreciated if available in c#, also f# version appreciated.

F#:

open System.Collections.Generic 
let r = new List<_>( [1..60] )

C#:

var r = new List<int>(Enumerable.Range(1, 60));

In F#, I would probably write:

[ 1 .. 60 ] |> ResizeArray.ofSeq

This is the same as calling the constructor explicitly, but it has a little nicer syntax (you can use pipelining and you don't need to specify type parameter of the constructor).

This would do it for the C# version:

List<int> mins = Enumerable.Range(1, 60).ToList();

That will loop internally, admittedly. If you are happy with an IEnumerable<int> instead, just knock off the ToList call and you'll get lazy evaluation. You've already got F# versions now, I see :)

List<_> in C# is a dynamic array, not linked list. In F#, List<_> is ResizeArray<_>.

Here's the directly translated F# version:

let mins = new ResizeArray<int> ()
for i=0 to 60-1 do
    mins.Add(i+1)

You can use ResizeArray module:

#r "FSharp.PowerPack.dll"
let mins = ResizeArray.init 60 (fun i -> i+1)

Notice that the ResizeArray<_> type is defined in F# Core, the same name module is in F# PowerPack.
