How do I use a SqlDataReader to get two columns of data?

If I wanted the password associated with a userName, this would work:

cmd = new SqlCommand("Select pw from [userTable] where login='" + userName + "'", conn);

if (reader.Read())
{
    lookupPassword = (string)reader[0];
}

But what if I wanted the password and a second column of information?  Hw would I get this from the reader?  What if my query were:

cmd = new SqlCommand("Select pw, roleID from [userTable] where login='" + userName + "'", conn);


The first row of data would still be reader[0].  But how would I differentiate between the pw and roleID columns?

Thanks,

I think this is
 lookupRole = (string)reader[1];

You can use the title of the column to fetch the column

e.g. reader("pw") and reader("roleID")

(vb style)

Hope this helps..
