How do I change the IP address of the adapter?

I want to set the IP address in the adapter. I got some links for the code below. but after doing this, when I check the adapter ip address, it doesn't change. It always shows me the old ip address. Don't specify any errors / exceptions. How do I change the IP address of the adapter?
