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

$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？
