This article covers how to talk to Active Directory and should get you where you want to go: http://www.codeproject.com/KB/system/everythingInAD.aspx

To get users, you would do something like this:

public List GetUserList()
{
        string DomainName="";
        string ADUsername="";
        string ADPassword="";

        List list=new List();
        DirectoryEntry entry=new DirectoryEntry(LDAPConnectionString, ADUsername, ADPassword);
        DirectorySearcher dSearch=new DirectorySearcher(entry);
        dSearch.Filter="(&(objectClass=user))";

        foreach(SearchResult sResultSet in dSearch.FindAll())
        {
            string str=GetProperty(sResultSet, "userPrincipalName");
            if(str!="")
                list.Add(str);
        }
        return list;
}
