There are no easy answers. This question has been asked many times. There have been very many very long discussions. One way to answer the question is to say that you can make it difficult for some people to use your software without paying for it but it is nearly impossible to prevent everyone from doing that. It is a matter of how complicated you want to be and how technical you want to make it for others to figure out the protection. You don't want to make it difficult for your paying customers. Also with C# and .Net you need to protect your source code from people that want to see hows you do that you do. That is different from what you are asking here.
