Hi All: Morning.

Is there any way to change Network adapter properties from DHCP to static like IP address, Subnet, gateway & DNS using Network Interface class.

From the link, i dont see any example; there is a plenty of example to get/read ipaddress, gateway etc...but not for set ip address or i may i'm missed to read/look properly.

Could you please provide me an exeple to set static IP using NetworkInterface class? i know we can set static IP using Win32, Management Object or using Netsh. Thnaks

Hi,@Kran2022 . Welcome Microsoft Q&A.

As you said, the documentation shows that the NetworkInterface class does not have some set methods. It doesn't seem to be able to set the IP through NetworkInterface.

I agree with you finally i adapted the below code using netsh hoefully it'll be useful for someone. Thanks

string fileName = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.System), "netsh");  
            Process.Start(new ProcessStartInfo(fileName)  
            {  
                Arguments = string.Format("interface ip set address \"{0}\" static {1} {2} {3}", nicname, ipaddressstatic, ipaddresssubnet, ipaddressgateway),  
                CreateNoWindow = true,  
                WindowStyle = ProcessWindowStyle.Hidden  
            }).WaitForExit();  
            Process.Start(new ProcessStartInfo(fileName)  
            {  
                Arguments = string.Format("interface ip set dns \"{0}\" static {1} Primary", nicname, ipaddressprefdns),  
                CreateNoWindow = true,  
                WindowStyle = ProcessWindowStyle.Hidden  
            }).WaitForExit();
