如何在PowerShell中向数组动态添加元素? [英] How do I dynamically add elements to arrays in PowerShell?

问题描述

我还没有太多的PowerShell经验，所以我会自学.

I don't have much PowerShell experience yet and am trying to teach myself as I go along.

我正在尝试为更大的项目做一些概念验证代码.这里的主要目标是过于动态地使用函数创建元素并将元素添加到数组中.

I'm trying to make some proof of concept code for a bigger project. The main goal here is too dynamically create and add elements to an array using a function.

这是我的代码:

$testArray = @()
function addToArray($Item1)
{
    $testArray += $Item1
    "###"
}

$tempArray = "123", "321", "453"
$foldertest = "testFolder"

foreach($item in $tempArray)
{
    addToArray $item
}
"###"

函数每次完成数组都会变为空. 请记住，我的大部分编程经验都来自Java，PHP，一些C和C ++，仅举几例，如果我使用PHP(当然，要调整语言语法)来完成此工作，就可以了.

Every time the function finishes the array becomes empty. Bear in mind most of my programming experience comes from Java, PHP, some C and C++ just to name a few, if I did this in PHP (adjusting the language syntax of course) this would have worked fine.

推荐答案

$testArray = [System.Collections.ArrayList]@()
$tempArray = "123", "321", "453"

foreach($item in $tempArray)
{
    $arrayID = $testArray.Add($item)
}
