从WMI获取网络接口IP信息(摘抄)

本文摘抄自《C#网络应用编程》 电子工业出版社  [美]Richard Blum著

根据需要做了些小小变动。

PS：WMI的详信息可以看MSDN

using  System.Management; 
 
class  WMICardGrab 
{ 
      public   static   void  Main() 
      { 
          string  _getIPcmd  =   " SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled = 'TRUE' " ; 
 
         ManagementObjectSearcher query  =   new  ManagementObjectSearcher(_getIPcmd); 
         ManagementObjectCollection queryCollection  =  query.Get(); 
 
          foreach (ManagementObject mo  in  queryCollection) 
          { 
              string [] addresses  =  ( string [])mo[ " IPAddress " ]; 
              string [] subnets  =  ( string [])mo[ " IPSubnet " ]; 
              string [] defaultgateways  =  ( string [])mo[ " DefaultIPGateway " ]; 
 
             Console.WriteLine( " 网卡: {0} " , mo[ " Description " ]); 
             Console.WriteLine( " \tMAC地址: {0} " , mo[ " MACAddress " ]); 
 
              foreach ( string  ipaddress  in  addresses) 
              { 
                 Console.WriteLine( " \tIP地址: {0} " , ipaddress); 
             }  
 
              foreach ( string  subnet  in  subnets) 
              { 
                 Console.WriteLine( " \t子网掩码: {0} " , subnet); 
             }  
 
              foreach ( string  defaultgateway  in  defaultgateways) 
              { 
                 Console.WriteLine( " \t默认网关: {0} " , defaultgateway); 
             }  
         }  
         Console.ReadLine(); 
     }
