如何在 Powershell 中对多维数组进行排序 [英] How to sort a Multi Dimensional Array in Powershell

问题描述

我有一个脚本可以定期清理文件夹.每个月都会创建 3-4 个子文件夹；我想要完成的是每月保留一个文件夹，并删除每台服务器上该文件夹上的其余文件夹.我成功地使用了脚本，但遇到了下面的块.

I have a script to cleanup a folder regularly. Every month there are 3-4 sub folders created; what i am trying to accomplish is keep a single folder per month and delete the rest on that folder on every server. I was successfull with the script, but ran into below block.

我的数组如下所示；

$Array = ((Filepath,Timestamp2),(Filepath,Timestamp3),(Filepath,Timestamp1),(Filepath,Timestamp4))

我想做的是，按时间戳对数组中的元素进行排序；怎么做?如果对此有任何其他问题，请告诉我.

What i would like to do is, sort elements in array by timestamp; how to do that? Please let me know if any other questions regarding this.

推荐答案

我的建议是将数组数组转换为自定义对象列表，并按 Timestamp 属性对该列表进行排序:

My recommendation would be to convert the array of arrays into a list of custom objects and sort that list by the Timestamp property:

$array | ForEach-Object {
  New-Object -Type PSCustomObject -Property @{
    Filepath  = $_[0]
    Timestamp = $_[1]
  }
} | Sort-Object Timestamp
