Powershell中的哈希表 [英] hash tables in powershell

问题描述

我正在使用PowerShell开发应用程序.我将变量存储在哈希表中.如何将订单保留在哈希表中?我希望顺序与填充哈希表时的顺序相同.

I'm developing an application in PowerShell. I am storing variables in a hashtable. How can I keep the order in the hashtable? I want the order to be the same as I when I filled the hashtable.

推荐答案

哈希表本质上并不维护值的顺序. 网上已经有一些解决方法.检查这些

Hash tables by nature don't maintain the order of values. There are a few workarounds already out on the net. Check these

或尝试

PS C:\WINDOWS\system32> $OrderedList = New-Object System.Collections.Specialized.OrderedDictionary
PS C:\WINDOWS\system32> $OrderedList
PS C:\WINDOWS\system32> $OrderedList.Add("Name","Ravi")
PS C:\WINDOWS\system32> $OrderedList.Add("Age","30")
PS C:\WINDOWS\system32> $OrderedList

Name                           Value
----                           -----
Name                           Ravi
Age                            30
