用System.Managment class 試試

下面是我在網上找到的代碼

代碼如下：

// This code demonstrates how to monitor the UsbControllerDevice for

// the arrival of creation/operation events

using System;

using System.ComponentModel;

using System.Runtime.InteropServices;

using System.Management;

class WMIEvent {

public static void Main() {

WMIEvent we = new WMIEvent();

ManagementEventWatcher w= null;

WqlEventQuery q;

ManagementOperationObserver observer = new ManagementOperationObserver();

// Bind to local machine

ManagementScope scope = new ManagementScope("root\\CIMV2");

scope.Options.EnablePrivileges = true; //set required privilege

try {

q = new WqlEventQuery();

q.EventClassName = "__InstanceOperationEvent";

q.WithinInterval = new TimeSpan(0,0,3);

q.Condition = @"TargetInstance ISA 'Win32_DiskDrive' ";

w = new ManagementEventWatcher(scope, q);

w.EventArrived += new EventArrivedEventHandler(we.DiskEventArrived);

w.Start();

Console.ReadLine(); // block main thread for test purposes

}

catch(Exception e) {

Console.WriteLine(e.Message);

}

finally {

w.Stop();

}

}

public void DiskEventArrived(object sender, EventArrivedEventArgs e) {

//Get the Event object and display its properties (all)

foreach(PropertyData pd in e.NewEvent.Properties) {

ManagementBaseObject mbo = null;

if(( mbo = pd.Value as ManagementBaseObject) != null) {

Console.WriteLine("--------------Properties------------------");

foreach(PropertyData prop in mbo.Properties)

Console.WriteLine("{0} - {1}", prop.Name, prop.Value);

}

}

}

}
