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，然後讓你的軟件只能運行在有這樣的CPU序列號的機器上。衆所周知，CPU序列號是唯一的！因此，這樣就可以爲你的軟件加鎖了。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餘空間。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：獲取有關係統內存的信息，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;

爲了獲取硬件信息，你還需要創建一個ManagementObjectSearcher 對象。

ManagementObjectSearcher searcher = new ManagementObjectSearcher("select * from " + Key);

首先，調用ManagementObjectSearcher實例（在本文中的例子裏爲searcher ）中的Get()方法，該方法將會把返回信息填在這個實例中。然後，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，當然我們可以接着這麼處理這些數據：

foreach (PropertyData PC in share.Properties){//some codes ...}

本文中代碼的其它部分只是對於ListView控件的一些操作，很簡單，就不再詳述了！
