C#精髓
第二讲 WMI完美秀出CPU编号厂商主频电压等全部信息
作者：清清月儿
主页：http://blog.csdn.net/21aspnet/ 时间：2007.3.23
关于WMI MSDN有详细说明。本文列举数例算抛砖引玉吧。WMI是个好东西，看过本文后也许你应该能举一反三参考MSDN也许自己做个优化大师也是可能的。
本文的例子在以下环境调试通过：Windows2003+AMD64双核CPU+VisualStudio2005(C#)下调试通过，无错版！
首先要添加“引用”一个dll，选择“System Management”；
再引入2个命名空间：
using System.Management;
using System.IO;
foreach循环：声明一个迭代变量自动获取数组中每个元素的值。
String.Format：格式化字符，本站就有解释。
代码：
