How Do I Get User Information From Active Directory

I have an ASP.NET application that uses LDAP to authenticate users against active directory. Once authenticated, I would like to get logged in user name and email so that I can send email. The log in part works, but how do I go about getting the user name (not username, but actual full name) and e-mail address? Also, how can I store the result so I can refer to it using parameters so that I can send email? Thanks in advance
