本文在ASP.NET程序中實現了獲取CPU編號、硬盤編號等與系統有關環境屬性，這個方法也可以移植到其他程序當中。

CpuInfo.cs

using System;
using System.Configuration;
using System.Runtime.InteropServices;

/**//**
* LayoutKind.Automatic：為了提高效率允許運行態對類型成員重新排序
* 注意：永遠不要使用這個選項來調用不受管轄的動態鏈接庫函數。
* LayoutKind.Explicit：對每個域按照FieldOffset屬性對類型成員排序
* LayoutKind.Sequential：對出現在受管轄類型定義地方的不受管轄內存中的類型成員進行排序。
*/

另外還定義了一個調用類SystemInfo.cs，代碼如下：
using System;
using System.Configuration;
using System.Runtime.InteropServices;
using System.Management;
using System.Text;

 foreach (ManagementObject mo in moc)
 ...{

 }
 return cpuId;

 return hardDiskID;

以下是調用實例，為了簡單，我在一個aspx頁面中輸出，不過這個程序可以在WinForm中調用：
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Collections.Specialized;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Runtime.InteropServices;

public partial class Index : System.Web.UI.Page
...{

 ...{
 if (!Page.IsPostBack)
 ...{
 SystemInfo systemInfo = new SystemInfo();
 Response.Write("操作系統：" + systemInfo.GetOperationSystemInName() + " ");

 Response.Write("系統目錄所在位置：" + systemInfo.GetWinDirectory() + " ");
 MemoryInfo memoryInfo = systemInfo.GetMemoryInfo();

 }
}
說明：前臺aspx頁面沒有任何控件。
