将arp-g的输出存储到powershell变量中

我只需要存储MAC地址信息（物理地址）

我只需要48-2a-e3-28-b0-f5

这是最接近我需要的，但我相信有最简单的方法：

$macarray = @()
arp -g 10.205.128.115 | Foreach{ 

        $obj = New-Object PSObject -Property @{
        #IP  = ($_ -split "\s+")[1]
        MAC = ($_ -split "\s+")[2]
        }
IF (!($obj.MAC -eq "---" -or $obj.MAC -eq "Address" -or $obj.MAC -eq $null -or $obj.MAC -eq "ff-ff-ff-ff-ff-ff")) {$macarray += $obj}
}
$macarray






$macarray = @()
arp -g 10.205.128.115 | Foreach{ 

        $obj = New-Object PSObject -Property @{
        #IP  = ($_ -split "\s+")[1]
        MAC = ($_ -split "\s+")[2]
        }
IF (!($obj.MAC -eq "---" -or $obj.MAC -eq "Address" -or $obj.MAC -eq $null -or $obj.MAC -eq "ff-ff-ff-ff-ff-ff")) {$macarray += $obj}
}
$macarray

这管用！但我认为这个解决方案是“稳健的”

我认为您最好按照建议使用

Get-CimInstance

或

Get-WmiObject

，而不是尝试解析arp命令的输出：

Get-CimInstance -ClassName Win32_NetworkAdapterConfiguration | 
    Where-Object { $_.IPAddress -match '\S+' } | 
    Select-Object @{Name = 'Internet Address'; Expression = {$_.IPAddress[0]}}, 
                  @{Name = 'Physical Address'; Expression = {$_.MACAddress}}, 
                  @{Name = 'Type'; Expression = {if ($_.DHCPEnabled) {'dynamic'} else {'static'}}}, 
                  Description

上面的输出类似于：

上面的输出类似于：

• 您可以使用正则表达式更好地解析arp输出
• Windows 8+/Windows Server 2012+具有

  Get-NetNeighbor

  cmdlet

这是为了在您的网络上获取计算机的MAC吗？如果是这样，您可以使用

获取CimInstance

获取所需信息。这是为了获取网络上计算机的MAC吗？如果是这样，您可以使用

Get cimpinstance

获取所需信息。对于带有LAPS的远程Win10计算机，ARP是最简单的解决方案。但是，感谢您使用LAPS的远程Win10计算机是最简单的ARP解决方案。但是谢谢你
