How to set folder security permissions?

Question

I am writing a program to simplify the creation of user accounts. Currently it creates an account in the specified OU, fills in all the pertinent user information such as first/last name, password, login script, home folder, and adds the user to a group. It also creates the indicated home folder (located at \\server\users\username). The one thing I have not been able to figure out is how to set the security permissions for the home directory. I want to give the user full rights to his home directory, but can't find any sample code on how to do that operation in a C#.NET environment. I've also been told that it's helpful to set the owner of the home folder to the assigned user. Any pointers on this topic would be greatly appreciated!
