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 initializes an EnumerationOptions variable with an EnumerationOptions constructor and then gets all the instances of a WMI class and its subclasses.


using System;
using System.Management;
public class RemoteConnect 
{
    public static void Main() 
    {
        EnumerationOptions opt = new EnumerationOptions();
        opt.DirectRead = false;
        // Will enumerate instances of the given class
        // and any subclasses.
        opt.EnumerateDeep = true;
        ManagementClass c = new ManagementClass("CIM_Service");
        foreach (ManagementObject o in c.GetInstances(opt))
            Console.WriteLine(o["Name"]);
    }
}
