下面就具体的代码作一说明：
1、C#
public string CpuID
{//要引用“using System.Management;”
get
{
string strProcessorId; ManagementObjectSearcher opSearch; ManagementObjectCollection mocSystem; strProcessorId=""; try { opSearch = new ManagementObjectSearcher("SELECT * FROM Win32_Processor"); mocSystem=opSearch.Get();//Win32_Processor：在MSDN查找 foreach( ManagementObject opInfo in mocSystem) {//返回所有CPU的ID，分别返回可修改下述语句 strProcessorId+= opInfo["ProcessorId"].ToString().Trim() ; //ProcessorId：在MSDN查找更多
} } catch { //TO DO：添加异常处理 } return strProcessorId; }
}public string DiskDrive {//硬盘厂商 get { string strDiskDrive; ManagementObjectSearcher opSearch; ManagementObjectCollection mocSystem; strDiskDrive=""; try { opSearch = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive"); mocSystem=opSearch.Get(); foreach( ManagementObject opInfo in mocSystem) { strDiskDrive+= opInfo["PNPDeviceID"].ToString().Trim() ; } } catch { //TO DO：添加异常处理 } return strDiskDrive; } } 2、C++
代码框架，你所要做的仅是修改WQL语句，具体可看MSDN。以下代码为简介起见，一次返回所有的CPUID或硬盘厂商系列号。
