用mysql-connector-net驱动连接MySql数据库

来源：互联网发布：金牛考勤软件怎么用编辑：程序博客网时间：2024/05/21 19:43

我的环境是：VS2005

1.去http://dev.mysql.com/downloads/connector/net/5.0.html上下载一个驱动程序，我下载的是mysql-connector-net-5.0.9.exe安装文件，下载安装完成后相关的MySql.Data.dll就会加载到C:/Program Files/MySQL/MySQL Connector Net 5.0.9/Binaries/.NET 2.0路径下。

2.在项目中选择添加引用,选择.NET，找到刚安装的MySql.Data确定

3.相关的简单测试如下

using System;
using System.Collections.Generic;
using System.Text;
using System.Data;
using MySql.Data.MySqlClient;

namespace MySQLTest
{
    public class MySQLDBHelper
    {
        private static MySqlConnection conn;
        private static MySqlCommand cmd;
        public static MySqlCommand GetCommand(string sql, MySqlParameter[] param)
        {
            conn = new MySqlConnection("UserId=sa;Host=localhost;Database=school;Password=sa");
            if (conn.State == ConnectionState.Closed)
                conn.Open();
            cmd = new MySqlCommand(sql,conn);
            if (param != null)
            {
                cmd.Parameters.AddRange(param);
            }
            return cmd;
        }

        public static void Main(string[] args)
        {
            string sql = "select * from student";
            using (MySqlDataReader rd = GetDataReader(sql, null))
            {
                while (rd.Read())
                {
                    Console.WriteLine(rd["stu_name"].ToString());
                }
            }
        }
    }
}
