Question

I am wondering if the following code is an old approach for working with database. Or I can use more modern and productive approach?

using(SqlConnection con = new SqlConnection(Properties.Settings.Default.EventLogPrinterConnectionString))
{
    SqlCommand com = new SqlCommand("", con);

    string sql_com_sel = "";
    sql_com_sel = @"SELECT DISTINCT Users, Pages, Date FROM View_lastactiveUser WHERE (Date >= @ds AND Date <= @dp AND Pages > 0) ORDER BY Date";
    com.CommandText = sql_com_sel;
    com.Parameters.Clear();
    com.Parameters.Add("@ds", SqlDbType.DateTime).Value = ds;
    com.Parameters.Add("@dp", SqlDbType.DateTime).Value = dp;
    con.Open();
    SqlDataReader dr = com.ExecuteReader();
    while (dr.Read())
    {
        users.Add(new UserDemo() { LastActivity = dr["Date"].ToString(), Pages = int.Parse(dr["Pages"].ToString()), User = dr["Users"].ToString() });
    }
    con.Close();
    return users;
}

you could use LinqtoSQL or The ADO.NET Entity Framework Overview

There are also some other solutions like nHibernate, but the first to come nativly with .NET
