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();  
   }  
  }
