Configuring TCP/IP settings by WMI. 用WMI对象访问.设置IP配置

 

WMI Extends the possibilities of .NET and simplifies the life while working on NetworkAdapters. The Following Code snippet lists all the Network adapters along with the IP Address, Subnet Mask, Default Gateway.

////////////////////////////////////////////--List Settings--////////////////////////////////////////////////////
public void ListIP() 
{
 ManagementClass objMC = new ManagementClass(
    "Win32_NetworkAdapterConfiguration"); 
 ManagementObjectCollection objMOC = objMC.GetInstances(); 
 
foreach(ManagementObject objMO in objMOC) 
{ 
          if(!(bool)objMO["ipEnabled"]) 
                 continue; 


        
          Console.WriteLine(objMO["Caption"] + "," + 
            objMO["ServiceName"] + "," + objMO["MACAddress"]) ; 
          string[] ipaddresses = (string[]) objMO["IPAddress"]; 
          string[] subnets = (string[]) objMO["IPSubnet"]; 
          string[] gateways = (string[]) objMO["DefaultIPGateway"]; 

   
          Console.WriteLine("Printing Default Gateway Info:"); 
          Console.WriteLine(objMO["DefaultIPGateway"].ToString()); 
          
          Console.WriteLine("Printing IPGateway Info:"); 
          foreach(string sGate in gateways) 
               Console.WriteLine (sGate); 

 
          Console.WriteLine("Printing Ipaddress Info:"); 

          foreach(string sIP in ipaddresses) 
               Console.WriteLine(sIP);
