    private void GetInfo()

        string cpuInfo = "";//cpu序列号
        ManagementClass cimobject = new ManagementClass("Win32_Processor");
        ManagementObjectCollection moc = cimobject.GetInstances();
        foreach (ManagementObject mo in moc)
        {
            cpuInfo = mo.Properties["ProcessorId"].Value.ToString();
            Response.Write("cpu序列号：" + cpuInfo.ToString()+"<br>");
        }

        //获取硬盘ID
        String HDid;
        ManagementClass cimobject1 = new ManagementClass("Win32_DiskDrive");
        ManagementObjectCollection moc1 = cimobject1.GetInstances();
        foreach (ManagementObject mo in moc1)
        {
            HDid = (string)mo.Properties["Model"].Value;
            Response.Write("硬盘序列号：" + HDid.ToString() + "<br>");
        }


        //获取网卡硬件地址

        ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
        ManagementObjectCollection moc2 = mc.GetInstances();
        foreach (ManagementObject mo in moc2)
        {
            if ((bool)mo["IPEnabled"] == true)
                Response.Write("MAC address：" + mo["MacAddress"].ToString() + "<br>");
            mo.Dispose();
        }


        //主板
        string strbNumber = string.Empty;
        ManagementObjectSearcher mos = new ManagementObjectSearcher("select * from Win32_baseboard");
        foreach (ManagementObject mo in mos.Get())
        {
            strbNumber += mo["SerialNumber"].ToString();
            break;
        }

        Response.Write("主板序号："+strbNumber);



    }

}

运行结果：

cpu序列号：BF************
硬盘序列号：TOSHIBA ******

MAC address：**:**:**:**

主板序号：QTFSFASFASFASF
