[i]适用于 PowerShell 所有版本[/i]
WMI 是一个很棒很强大的技术：只需要指定一个 WMI 类名，您就可以获取该类的所有实体。[code]
PS> Get-WmiObject -Class Win32_BIOS
SMBIOSBIOSVersion : 76CN27WW
Manufacturer : LENOVO
Name : 76CN27WW
SerialNumber : 1006250300406
Version : LENOVO - 1
[/code]那么如何知道有哪些 WMI 类呢？以下是一个搜索工具函数：[code]
function Find-WMIClass
{
param
(
[Parameter(Mandatory=$true)]
$SearchTerm = 'Resolution'
)
Get-WmiObject -Class [i] -List [/i]
Where-Object { $[i].Properties.Count -ge 3 } [/i]
Where-Object { $[i].Name -notlike 'Win32[/i]Perf[i]' } [/i]
Where-Object {
$ListOfNames = $_.Properties | Select-Object -ExpandProperty Name
($ListOfNames -like "*$SearchTerm*") -ne $null
} |
Sort-Object -Property Name
}
[/code]只需要指定一个搜索条件。该函数将会查找所有属性名中包含搜索条件的 WMI 类（可以用通配符来扩大搜索范围）。
这段代码能搜索属性以“resolution”结尾的 WMI 类：[code]
PS> Find-WMIClass -SearchTerm *resolution

[/code]下一步，选择一个类名并观察它的实际数据：[code]
PS> Get-WmiObject -Class CIM[i]CacheMemory [/i] Select-Object -Property *
