PowerShell:格式化Get-WmiObject输出以仅返回IP地址

Question

我想使用Get-WmiObject Win32_NetworkAdapterConfiguration来返回网卡的IP地址.不幸的是,我无法弄清楚如何格式化输出以仅显示IPv.4地址.

Get-WmiObject Win32_NetworkAdapterConfiguration | Select IPAddress | Where-Object {$_.IPaddress -like "192.168*"}

显示:

IPAddress
---------
{192.168.56.1, fe80::8980:15f4:e2f4:aeca}

以上面的输出为例,我希望它只返回192.168.56.1(有些客户端有多个NIC,因此是"Where-Object")

Answer 1

该IPAddress属性是一个string[],所以下面应该这样做:

gwmi Win32_NetworkAdapterConfiguration |
    Where { $_.IPAddress } | # filter the objects where an address actually exists
    Select -Expand IPAddress | # retrieve only the property *value*
    Where { $_ -like '192.168.*' }
