Powershell - 将文本字段转换为对象

Question

我试图找到一种优雅的方式将下面的数据转换为Powershell对象的集合,但不幸的是我无法找到一种简单的方法.有人能帮助我吗？

名称:ENC1
IPv4地址:172.16.2.101
链接设置:强制,100 Mbit,全双工
名称:ENC2
IPv4地址:172.16.2.103
链接设置:强制,100 Mbit,全双工
名称:ENC3
IPv4地址:172.16.2.103
链接设置:强制,100 Mbps,全双工
名称:ENC4
IPv4地址:172.16.2.104
链接设置:强制,100 Mbps,全双工

这就是我提出的.

$ out = @()
$ text = Get-Content input.txt
$ count = 0
do {
$ line =($ text | select -Skip $ count -first 3)
$ obj =""| 选择名称,IP,设置
$ obj.Name = $ line [0] .split(":")[1]
$ obj.IP = $ line [1] .split(":")[1]
$ obj.Settings = $ line [2] .split(":")[1]
$ out + = $ obj
$ count = $ count + 3
} until($ count -eq $ text.count)
$ out

这样做有简单的方法吗？

使用开关:

$data = (@'
Name: ENC1
 IPv4 Address: 172.16.2.101
 Link Settings: Forced, 100 Mbit, Full Duplex
 Name: ENC2
 IPv4 Address: 172.16.2.103
 Link Settings: Forced, 100 Mbit, Full Duplex
 Name: ENC3
 IPv4 Address: 172.16.2.103
 Link Settings: Forced, 100 Mbps, Full Duplex
 Name: ENC4
 IPv4 Address: 172.16.2.104
 Link Settings: Forced, 100 Mbps, Full Duplex
'@).split("`n") |
foreach {$_.trim()}

Switch -Regex ($data) 
{
 '^Name: (.+)' {$obj = [PSCustomObject]@{Name=$Matches[1];IP=$null;Settings=$null}}
 '^IPv4 Address: (.+)' {$obj.IP = $matches[1]}
 '^Link Settings: (.+)' {$obj.Settings = $Matches[1];$obj}
}



Name                                 IP                                   Settings                            
----                                 --                                   --------                            
ENC1                                 172.16.2.101                         Forced, 100 Mbit, Full Duplex       
ENC2                                 172.16.2.103                         Forced, 100 Mbit, Full Duplex       
ENC3                                 172.16.2.103                         Forced, 100 Mbps, Full Duplex       
ENC4                                 172.16.2.104                         Forced, 100 Mbps, Full Duplex       

编辑:经过一番考虑后,我觉得我更喜欢这种模式:

$DefValue = 'Parse error. Check input.'
Switch -Regex ($data) 
{
 '^Name: (.+)' {$obj;$obj = [PSCustomObject]@{Name=$Matches[1];IP=$DefValue;Settings=$DefValue}}
 '^IPv4 Address: (.+)' {$obj.IP = $matches[1]}
 '^Link Settings: (.+)' {$obj.Settings = $Matches[1]}
}
