创建 WMI 类并添加静态属性或默认值 [英] Create WMI class and add static property or default value

问题描述

我正在尝试创建一个 WMI 类并添加一个静态属性，或设置该属性的默认值

I'm trying to create a WMI class and add a static property, or set the default value of the property

$WMI_Class = New-Object System.Management.ManagementClass("root\default", $null, $null)
$WMI_Class.Qualifiers.Add("Static", $true)
$WMI_Class.Properties.Add("ver", [System.Management.CimType]::String, "myDefaultValue")
$WMI_Class.name = "MyCoreClass"
$WMI_Class.Put()

$obj = ([WmiClass] 'root\default:MyCoreClass')
$ver = $obj.Properties['ver'].Value
$ver

类已创建，但 $ver 为空，有什么想法吗?

The class is created but the $ver is empty, any ideas?

推荐答案

将您的代码更改为:

$WMI_Class = New-Object System.Management.ManagementClass("root\default", [String]::Empty, $null)
$WMI_Class.name = "MyCoreClass"
$WMI_Class.Properties.Add("ver", "Hi, This is sample static value")
$WMI_Class.Put()

$obj = ([WmiClass] 'root\default:MyCoreClass')
$ver = $obj.Properties['ver'].Value
$ver
