将PowerShell数组切成小数组 [英] Slice a PowerShell array into groups of smaller arrays

问题描述

我想根据一个变量将单个数组转换为一组较小的数组。因此， 0,1,2,3,4,5,6,7,8,9 将变为 0,1,2 ， 3,4,5 ， 6,7,8 ， 9 当大小为3时。

I would like to convert a single array into a group of smaller arrays, based on a variable. So, 0,1,2,3,4,5,6,7,8,9 would become 0,1,2,3,4,5,6,7,8,9 when the size is 3.

我当前的做法：

$ids=@(0,1,2,3,4,5,6,7,8,9)
$size=3

0..[math]::Round($ids.count/$size) | % { 

    # slice first elements
    $x = $ids[0..($size-1)]

    # redefine array w/ remaining values
    $ids = $ids[$size..$ids.Length]

    # return elements (as an array, which isn't happening)
    $x

} | % { "IDS: $($_ -Join ",")" }

产生：

IDS: 0
IDS: 1
IDS: 2
IDS: 3
IDS: 4
IDS: 5
IDS: 6
IDS: 7
IDS: 8
IDS: 9

我希望它是

IDS: 0,1,2
IDS: 3,4,5
IDS: 6,7,8
IDS: 9

我想念什么？

推荐答案

您可以使用，$ x 而不只是 $ x 。

<$ c文档中$ c> about_Operators 部分具有以下内容：

, Comma operator                                                  
   As a binary operator, the comma creates an array. As a unary
   operator, the comma creates an array with one member. Place the
   comma before the member.
