C#获取cpu序列号,硬盘ID,网卡MAC地址

首先在添加引用中选中System.Management
再在开始部门：
using System.Management;
using System.Management.Instrumentation;
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 ()); 
   } 
   //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 ()); 
   } 
   //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\t{0}"+mo["MacAddress"].ToString()); 
    mo.Dispose(); 
   } 
  }
