在很多情况下，你可能都需要得到微机的硬件信息。比如：你想给你的软件加锁，不让别人随便访问。
最有效的办法是获取CPU的序列号，然后让你的软件只能运行在有这样的CPU序列号的机器上。众所周知，CPU序列号是唯一的！因此，这样就可以为你的软件加锁了。powered by 25175.net
另外一个需要硬盘信息的例子是：硬盘有几个分区，每个分区各有多少剩余空间。当你正在做一个多媒体应用程序的时候，你可能也需要获得有关声卡、显卡的硬件信息。
本应用程序另一个精彩的应用是：获取有关系统内存的信息，如内存地址，内存设备等等。
首先，你必须知道这个应用程序的功能是使用System.Management这个类得到的。因此，你需要加上下面的这句话：
using System.Management;
为了获取硬件信息，你还需要创建一个ManagementObjectSearcher 对象。
ManagementObjectSearcher searcher = new ManagementObjectSearcher("select * from " + Key);
// 硬件 Win32_Processor, // CPU 处理器 Win32_PhysicalMemory, // 物理内存条 Win32_Keyboard, // 键盘 Win32_PointingDevice, // 点输入设备，包括鼠标。 Win32_FloppyDrive, // 软盘驱动器 Win32_DiskDrive, // 硬盘驱动器 Win32_CDROMDrive, // 光盘驱动器 Win32_BaseBoard, // 主板 Win32_BIOS, // BIOS 芯片 Win32_ParallelPort, // 并口 Win32_SerialPort, // 串口 Win32_SerialPortConfiguration, // 串口配置 Win32_SoundDevice, // 多媒体设置，一般指声卡。 Win32_SystemSlot, // 主板插槽 (ISA & PCI & AGP) Win32_USBController, // USB 控制器 Win32_NetworkAdapter, // 网络适配器 Win32_NetworkAdapterConfiguration, // 网络适配器设置 Win32_Printer, // 打印机 Win32_PrinterConfiguration, // 打印机设置 Win32_PrintJob, // 打印机任务 Win32_TCPIPPrinterPort, // 打印机端口 Win32_POTSModem, // MODEM Win32_POTSModemToSerialPort, // MODEM 端口 Win32_DesktopMonitor, // 显示器 Win32_DisplayConfiguration, // 显卡 Win32_DisplayControllerConfiguration, // 显卡设置 Win32_VideoController, // 显卡细节。 Win32_VideoSettings, // 显卡支持的显示模式。

上面代码的Key是一个将被对应正确的数据填入的值。例如，获取CPU的信息，就需要把Key值设成Win32_Processor。所有Key可能的值，列举如下：

首先，调用ManagementObjectSearcher实例（在本文中的例子里为searcher ）中的Get()方法，该方法将会把返回信息填在这个实例中。然后，你所要做的就是处理这个实例searcher中的数据。
foreach (ManagementObject share in searcher.Get()){// Some Codes ...}
每个ManagementObject的对象中都有一些，我们所需要的数据，当然我们可以接着这么处理这些数据：
foreach (PropertyData PC in share.Properties){//some codes ...}
本文中代码的其它部分只是对于ListView控件的一些操作，很简单，就不再详述了！
