    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:

    复制代码 代码如下:

    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:

    复制代码 代码如下:

    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:

    复制代码 代码如下:

    PS> Find-WMIClass -SearchTerm *resolution


       NameSpace: ROOT\cimv2

    Win32_VideoController               {SetPowerState, R... {AcceleratorCapabiliti...
    Win32_VoltageProbe                  {SetPowerState, R... {Accuracy, Availabilit...

    接着,就可以使用类名查看它的有效数据啦:

    复制代码 代码如下:

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