C#精髓
第二講 WMI完美秀出CPU編號廠商主頻電壓等全部信息
作者：清清月兒
主頁：http://blog.csdn.net/21aspnet/?????????? 時間：2007.3.23
關于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，看過本文后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：
