Method 1: 1. In Solution Explorer, right-click reference and add a reference to system. Management.
2. Add "using system. Management ;".

Static void setnetworkadapter ()
{
Managementbaseobject inpar = NULL;
Managementbaseobject outpar = NULL;
Managementclass MC = new managementclass ("win32_networkadapterconfiguration ");
Managementobjectcollection MOC = mc. getinstances ();
Foreach (managementobject Mo in MoC)
{
If (! (Bool) Mo ["ipenabled"])
Continue;

// Set the IP address and subnet mask
Inpar = Mo. getmethodparameters ("enablestatic ");
Inpar ["IPaddress"] = new string [] {"192.168.16.248", "192.168.16.249"}; // 1. Backup 2.ip
Inpar ["subnetmask"] = new string [] {"255.255.255.0", "255.255.255.0 "};
Outpar = Mo. invokemethod ("enablestatic", inpar, null );

// Set the gateway address
Inpar = Mo. getmethodparameters ("setgateways ");
Inpar ["defaultipgateway"] = new string [] {"192.168.16.2", "192.168.16.254"}; // 1. Gateway; 2. Backup Gateway
Outpar = Mo. invokemethod ("setgateways", inpar, null );

// Set DNS
Inpar = Mo. getmethodparameters ("setdnsserversearchorder ");
Inpar ["dnsserversearchorder"] = new string [] {"211.97.168.129", "202.102.152.3"}; // 1.dns 2. Backup DNS
Outpar = Mo. invokemethod ("setdnsserversearchorder", inpar, null );
Break;
}
