问题 Similar to this question except that no answer was given with regards to the main question of getting an object from reference. For example: PS C:\Users\admin> Get-WmiObject -Namespace $namespace -Class $class ... IsActive : 1 oA: \\.\ROOT\abc\abc\ABC:abc.xyz="tst2" oB : \\.\ROOT\abc\abc\ABC:abc.xyz="tst3" PSComputerName : admin-test2 oA and oB are references and therefore come up as strings in powershell.

I could just make a list of running processes and attach an Exited event to them through the System.Diagnostics Namespace, but there is no Event Handler for creation. 回答1: This is not exactly how you'd do it in the real world but should
