ADO.NET使用MySqlCommand实例获取数据

using MySql.Data.MySqlClient;
using System;

namespace ConsoleTest
{
    class Program
    {
        static string connectionString =
            "server=localhost;user id=lqs2011;password=******;database=toucai";
        static void Main(string[] args)
        {
            MySqlConnection connection = new MySqlConnection(connectionString);
            connection.Open();
            if (connection.State == System.Data.ConnectionState.Open)
                Console.WriteLine("connection opened!");
            MySqlCommand cmd = new MySqlCommand();
            cmd.Connection = connection;
            cmd.CommandText = "SELECT empID, empNickName FROM employee";
            cmd.CommandType = System.Data.CommandType.Text;
            MySqlDataReader dataReader = cmd.ExecuteReader();
            if (dataReader.HasRows)
                Console.WriteLine("get data successfully!");  
            while (dataReader.Read())
                Console.WriteLine(dataReader.GetString(0)+ ‘\t‘ + dataReader.GetString(1));
        }
    }
}
输出结果：

connection opened!
get data successfully!
