Considering the abundance of information to interface with AD I am surprised that you have not stumbled upon one of the following links:

• Everything in Active Directory via C#.NET 3.5 (Using System.DirectoryServices.AccountManagement)
• Managing Directory Security Principals in the .NET Framework 3.5

These should get you started.
