适用于 PowerShell 所有版本
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。- PS> Get-WmiObject -Class Win32_BIOS
-
-
- SMBIOSBIOSVersion : 76CN27WW
- Manufacturer : LENOVO
- Name : 76CN27WW
- SerialNumber : 1006250300406
- Version : LENOVO - 1
复制代码
那么如何知道有哪些 WMI 类呢?以下是一个搜索工具函数:- 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
- }
复制代码
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:- PS> Find-WMIClass -SearchTerm *resolution
-
-
- NameSpace: ROOT\cimv2

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