關於WMI MSDN有詳細說明。 本文列舉數例算拋磚引玉吧。WMI是個好東西，看過本文後也許你應該能舉一反三參考MSDN也許自己做個優化大師也是可能的。
本文的例子在以下環境調試通過：Windows2003+AMD64雙核CPU+VisualStudio2005(C#)下調試通過，無錯版！
首先要添加“引用”一個dll，選擇“System Management”；
再引入2個命名空間：
using System.Management;
using System.IO;
foreach循環：聲明一個迭代變量自動獲取數組中每個元素的值。
String.Format：格式化字符，本站就有解釋。
代碼：
Form1.cs
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Management;
