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);

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！
