C#连接MySql数据库方法 宇兰

1、用MySQLDriverCS连接MySQL数据库
先下载和安装MySQLDriverCS，地址：http://sourceforge.net/projects/mysqldrivercs/在安装文件夹下面找到MySQLDriver.dll，然后将MySQLDriver.dll添加引用到项目中注：我下载的是版本是 MySQLDriverCS-n-EasyQueryTools-4.0.1-DotNet2.0.exe using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Data.Odbc;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;using MySQLDriverCS;  namespace mysql{    public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();        }         private void Form1_Load(object sender, EventArgs e)        {             MySQLConnection conn = null;            conn = new MySQLConnection(new MySQLConnectionString("localhost", "inv", "root", "831025").AsString);            conn.Open();             MySQLCommand commn = new MySQLCommand("set names gb2312", conn);            commn.ExecuteNonQuery();             string sql = "select * from exchange ";            MySQLDataAdapter mda = new MySQLDataAdapter(sql, conn);             DataSet ds = new DataSet();            mda.Fill(ds, "table1");      &n
