How to publish selected Web Method in Web Service c#

Question

how to publish selected methods in web services c# i.e. in my web service there are 3 web method present. I want to handle this method manually like on running web service only web method i choose should be run or published only and rest shouldn't be published. for eg say method1 is selected to run only so on running web service only method1 should be published on localhost and rest methods shouldn't be published. Please give me some idea.
