PS C:\Users\haife> Get-WmiObject -query "SELECT * FROM meta_class WHERE __class = 'Win32_LogicalDisk'"

   NameSpace:ROOT\cimv2

Name                                Methods              Properties
----                                -------              ----------
Win32_LogicalDisk                   {SetPowerState, R... {Access, Availability, BlockSize, Caption...}

如果执行  Get-WmiObject -query "SELECT * FROM meta_class"  ，则返回当前命名空间中所有的类定义。
