using System.Data;
using System.Data.SqlClient;
using System.Data.rumon;
class Program {
    static void Main(string[] args) {

        cnStrBuilder.InitialCatalog = "Cars";
        cnStrBuilder.DataSource = "(local)";
        cnStrBuilder.ConnectTimeout = 5;
        SqlConnection cn = new SqlConnection();
        cn.ConnectionString = cnStrBuilder.ConnectionString;
        cn.Open();
        ShowConnectionStatus(cn);

                Console.Write("{0} = {1} ",myDataReader.GetName(i),myDataReader.GetValue(i).ToString().Trim());
            }
        }
        myDataReader.Close();
        ShowConnectionStatus(cn);
