370.C#初探WMI（c#实验五）

Windows Management Instrumentation (WMI) is a robust tool in Windows for managing system data and operations. It operates on the Common Information Model (CIM), an informative model used to portray computer systems, applications, network devices etc. WMI enables administration and development roles to access vital data, monitor events, and execute tasks. This article introduces ways to use WMI to list CIM details and its benefits for system governance and automation.

Conducting CIM listings can be done via numerous instruments and scripting languages like PowerShell, VBScript or C#. Here, we will focus on utilizing PowerShell for this process.

Powershell, an efficient command line script language, offers built-in support for WMI. It enables easy listing and querying of CIM classes.

Below are basic Powershell commands for creating CIM lists:

This command provides all available CIM classes.

This shows information about all processes running in the system, as represented by Win32_Process.

This reveals all active services.

The code first defines a WMI query to select all Win32_OperatingSystem instances. Next, it uses ManagementObjectSearcher class to perform the query and traverse the results. For each operating system instance, crucial data such as name, version, maker, config path, system directory, boot device, memory info, etc., is displayed.

By delving into CIM details and executing queries, administrators and developers have several advantages they can take advantage of:

WMI and CIM present an effective technique for overseeing and automating Windows systems. PowerShell and other tools allow for simplified manipulation of CIM details, enabling automation of various tasks. Professionals across systems administration and development areas can improve their work effectiveness and system stability through better understanding and implementation of WMI and CIM.
