在很多情況下，你可能都需要得到微機的硬件信息。比如：你想給你的軟件加鎖，不讓別人隨便訪問。
最有效的辦法是獲取CPU的序列號，然后讓你的軟件只能運行在有這樣的CPU序列號的機器上。眾所周知，CPU序列號是唯一的！因此，這樣就可以為你的軟件加鎖了。powered by 25175.net
另外一個需要硬盤信息的例子是：硬盤有幾個分區，每個分區各有多少剩余空間。當你正在做一個多媒體應用程序的時候，你可能也需要獲得有關聲卡、顯卡的硬件信息。
本應用程序另一個精彩的應用是：獲取有關系統內存的信息，如內存地址，內存設備等等。
首先，你必須知道這個應用程序的功能是使用System.Management這個類得到的。因此，你需要加上下面的這句話：
using System.Management;
為了獲取硬件信息，你還需要創建一個ManagementObjectSearcher 對象。
ManagementObjectSearcher searcher = new ManagementObjectSearcher(“select * from ” + Key);
// 硬件 Win32_PRocessor, // CPU 處理器 Win32_PhysicalMemory, // 物理內存條 Win32_Keyboard, // 鍵盤 Win32_PointingDevice, // 點輸入設備，包括鼠標。 Win32_FloppyDrive, // 軟盤驅動器 Win32_DiskDrive, // 硬盤驅動器 Win32_CDROMDrive, // 光盤驅動器 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, // 多媒體設置，一般指聲卡。 Win32_SystemSlot, // 主板插槽 (ISA & PCI & AGP) Win32_USBController, // USB 控制器 Win32_NetworkAdapter, // 網絡適配器 Win32_NetworkAdapterConfiguration, // 網絡適配器設置 Win32_Printer, // 打印機 Win32_PrinterConfiguration, // 打印機設置 Win32_PrintJob, // 打印機任務 Win32_TCPipPrinterPort, // 打印機端口 Win32_POTSModem, // MODEM Win32_POTSModemToSerialPort, // MODEM 端口 Win32_DesktopMonitor, // 顯示器 Win32_DisplayConfiguration, // 顯卡 Win32_DisplayControllerConfiguration, // 顯卡設置 Win32_VideoController, // 顯卡細節。 Win32_VideoSettings, // 顯卡支持的顯示模式。

上面代碼的Key是一個將被對應正確的數據填入的值。例如，獲取CPU的信息，就需要把Key值設成Win32_Processor。所有Key可能的值，列舉如下：

首先，調用ManagementObjectSearcher實例（在本文中的例子里為searcher ）中的Get()方法，該方法將會把返回信息填在這個實例中。然后，你所要做的就是處理這個實例searcher中的數據。
foreach (ManagementObject share in searcher.Get()){// Some Codes ...}每個ManagementObject的對象中都有一些，我們所需要的數據，當然我們可以接著這么處理這些數據：
foreach (PropertyData PC in share.Properties){//some codes ...}本文中代碼的其它部分只是對于ListView控件的一些操作，很簡單，就不再詳述了！
