Chapter 10-Lesson 4

  • System.Management provides tools to check system resources using WMI (Windows Management Instrumentation)
  • ManagementObjectSearcher class is used to apply queries onto a system and retrieve useful information.
  • This object uses ManagementScope to determine the system name and Login information, and ObjectQuery to determine the SQL-like query to be used.
  • The Get( ) method invokes the query on the scope object and returns a ManaementObjectCollection.
  • Usually the query is of the form like Select * from Win32_LogicalDisk or Select * from Win32_Service WHERE Started = FALSE
  • ManagementEventWatcher class may be used to track and respond to events in the WMI context. (refer to Lab for specific example)
