ManagementClass.ManagementClass(ManagementScope, ManagementPath, ObjectGetOptions) Constructor

Initializes a new instance of the ManagementClass class for the specified WMI class in the specified scope and with the specified options. The class represents a Common Information Model (CIM) management class from WMI such as Win32_LogicalDisk, which can represent a disk drive, and Win32_Process, which represents a process such as Notepad.exe. For more information, see "Win32 Classes" in the Windows Management Instrumentation documentation in the MSDN Library at

public ManagementClass (
	ManagementScope scope,
	ManagementPath path,

public ManagementClass (

Not applicable.



A ManagementScope that specifies the scope (server and namespace) where the WMI class resides.


A ManagementPath that represents the path to the WMI class in the specified scope. The class represents a CIM management class from WMI. CIM classes represent management information including hardware, software, processes, and so on. For more information about the CIM classes available in Windows, see "Win32 classes" in the Windows Management Instrumentation documentation in the MSDN Library at


An ObjectGetOptions that specifies the options to use when retrieving the WMI class.

The path can be specified as a full path (including server and namespace). However, if a scope is specified, it will override the first portion of the full path.

Full trust for the immediate caller. This member cannot be used by partially trusted code. For more information, see Using Libraries from Partially Trusted Code.

The following example is an example of how to initialize a ManagementClass variable with a ManagementClass constructor. The example lists the methods, properties, and qualifiers (including the amended qualifiers) for the created class. You must change the scope (namespace) in the code for the example to run correctly on your computer.

using System;
using System.Management;

public class Sample 
    public static void Main() 

        // Get the WMI class
        ManagementScope s = 
            new ManagementScope("\\\\MyBox\\root\\cimv2");
        ManagementPath p = new ManagementPath("Win32_Environment");
        ObjectGetOptions o = new ObjectGetOptions(
            null, System.TimeSpan.MaxValue, true);
        ManagementClass c = new ManagementClass(s, p, o);

        // Get the methods in the class
        MethodDataCollection methods =

        // display the methods
        Console.WriteLine("Method Names: ");
        foreach (MethodData method in methods)

        // Get the properties in the class
        PropertyDataCollection properties =

        // display the properties
        Console.WriteLine("Property Names: ");
        foreach (PropertyData property in properties)

        // Get the Qualifiers in the class
        QualifierDataCollection qualifiers =

        // display the qualifiers
        Console.WriteLine("Qualifier Names: ");
        foreach (QualifierData qualifier in qualifiers)
