【问题描述】：

我的目标是单独输出每个 Group 对象，但按 Start_Order 的顺序。从 Count 中可以看到同一个 Server_Name 下有多个对象。

我现在的代码正在将所有内容打包在一起。

输出应该是：

Server_Name             Service_Name
USOHCLIENT901             DISP01   #organized by Start_Order, Start_Order =1
                          DISP03   #Start_Order =2
                          DISP05   #Start_Order =3

$Sourcefile = "C:\Users\StartF.csv"

$StartProperties  = (Import-Csv $Sourcefile)  | select Ava_Zone,Environment,Server_Name,
                                                Purpose,Service_Name, Start_Order, Start_Flag, 
                                                Start_Wait
# $StartProperties

$StartProperties | Group-Object -Property Server_Name | Sort-Object -Property {$_Start_Order}

Count Name                      Group                                          
----- ----                      -----

【解决方案1】：

看看下面的代码。它会做你正在寻找的东西，但适用于所有正在运行的进程。在Group-Object 之后，您可以使用Select-Object 和自定义创建的属性@{Name = 'Id'; Expression = {($_.Group.Id | Sort-Object) -join "rn"}} 直接选择您需要的属性，该属性将从Group-Object 组中收集数据并对其进行排序。

$Processes = Get-Process
$Processes | Group-Object -Property 'ProcessName' | Select-Object -Property 'Name', @{Name = 'Id'; Expression = {($_.Group.Id | Sort-Object) -join "`r`n"}} | Format-List
