Powershell中使用WMI工具例子

支持所有版本

WMI是一个强大的技术：只需要简单的指定一个WMI类名就能返回它类的所有实例：

PS> Get-WmiObject -Class Win32_BIOS

SMBIOSBIOSVersion : 76CN27WW Manufacturer : LENOVO Name : 76CN27WW SerialNumber : 1006250300406 Version : LENOVO - 1

你如何知道它有哪些类呢？这里有一款查找工具：


function Find-WMIClass

{

   param

   (

      [Parameter(Mandatory=$true)]

      $SearchTerm = 'Resolution'

   )

   

   Get-WmiObject -Class * -List | 

   Where-Object { $_.Properties.Count -ge 3 } |

   Where-Object { $_.Name -notlike 'Win32_Perf*'  } |

   Where-Object {

      $ListOfNames = $_.Properties | Select-Object -ExpandProperty Name

      ($ListOfNames -like "*$SearchTerm*") -ne $null

   } |

   Sort-Object -Property Name  

}

设置搜索条件后，代码将搜索出包含指定属性名的类（还可以通过通配符扩大搜索范围）

下面将找出所有包含“resolution”结尾的WMI类：

PS> Find-WMIClass -SearchTerm *resolution

NameSpace: ROOT\cimv2

Win32_VoltageProbe {SetPowerState, R... {Accuracy, Availabilit...

接着，就可以使用类名查看它的有效数据啦：


PS> Get-WmiObject -Class CIM_CacheMemory | Select-Object -Property *
