C# WMI获取硬件信息

http://hi.baidu.com/jackeyrain/blog/item/437bed7f706fa20328388a9f.html

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：

Form1.cs

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
