        // bind it to a 'real' manageable entity
        o.Path =
            new ManagementPath("Win32_LogicalDisk='c:'");

        //Now it can be used
        Console.WriteLine(o["FreeSpace"]);

Source:: ManagementObject.cs

Source:: ManagementObject.cs

Source:: ManagementObject.cs

Initializes a new instance of the ManagementObject class bound to the specified WMI path that includes the specified options.

public:
 ManagementObject(System::Management::ManagementScope ^ scope, System::Management::ManagementPath ^ path, System::Management::ObjectGetOptions ^ options);

scope: ManagementScope

A ManagementScope representing the scope in which the WMI object resides. In this version, scopes can only be WMI namespaces.

path: ManagementPath

A ManagementPath representing the WMI path to the manageable object.

options: ObjectGetOptions

An ObjectGetOptions specifying additional options for getting the object.

Examples

using System;
using System.Management;

class Sample
{
    public static int Main(string[] args)
    {

        Console.WriteLine(o.Qualifiers("Description").Value)

        Return 0
    End Function
End Class

Remarks

Because WMI paths can be relative or full, a conflict between the scope and the path specified may arise. However, if a scope is specified and a relative WMI path is specified, then there is no conflict. The following are some possible conflicts:

If a scope is not specified and a relative WMI path is specified, then the scope will default to the local machine's DefaultPath.

If a scope is not specified and a full WMI path is specified, then the scope will be inferred from the scope portion of the full path. For example, the full WMI path: \\MyMachine\root\MyNamespace:MyClass.Name='abc' will represent the WMI object 'MyClass.Name='abc'" in the scope '\\MyMachine\root\MyNamespace'.

If a scope is specified and a full WMI path is specified, then the scope will override the scope portion of the full path. For example, if the following scope was specified: \\MyMachine\root\MyScope, and the following full path was specified: \\MyMachine\root\MyNamespace:MyClass.Name='abc', then look for the following object: \\MyMachine\root\MyScope:MyClass.Name= 'abc' (the scope part of the full path is ignored).
