如何通过属性名称获取对象的属性值? [英] How to get an object's property's value by property name?

问题描述

在 PowerShell 中，如何通过指定名称(字符串)来获取对象的属性值?我想要类似以下内容:

In PowerShell, how do you get an object's property value by specifying its name (a string)? I want something like the following:

$obj = get-something

# View the object's members:
$obj | gm

# I could retrieve a property by doing so:
write-host $obj.SomeProp

# But for many purposes, I would really want to:
write-host $obj | Get-PropertyByName "SomeProp"

PowerShell 中是否有类似于Get-PropertyByName"的东西?

Is there something similar to "Get-PropertyByName" in PowerShell?

推荐答案

当然

write-host ($obj | Select -ExpandProperty "SomeProp")

或者就此而言:

$obj."SomeProp"
