1、用MySQLDriverCS連接MySQL數據庫

先下載和安裝MySQLDriverCS，地址：

http://sourceforge.net/projects/mysqldrivercs/

在安裝文件夾下面找到MySQLDriver.dll，然后將MySQLDriver.dll添加引用到項目中

注：我下載的是版本是 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");

            this.dataGrid1.DataSource = ds.Tables["table1"];

            conn.Close();

        }

    }

}

2、通過(guò)ODBC訪(fǎng)問(wèn)mysql數據庫：

參考：http://www.microsoft.com/china/community/Column/63.mspx

1.      安裝Microsoft ODBC.net：我安裝的是mysql-connector-odbc-3.51.22-win32.msi

2.      安裝MDAC 2.7或者更高版本：我安裝的是mdac_typ.exe 2.7簡(jiǎn)體中文版

3.      安裝MySQL的ODBC驅動(dòng)程序：我安裝的是 odbc_net.msi

4.      管理工具 -> 數據源ODBC –>配置DSN…

5.      解決方案管理中添加引用 Microsoft.Data.Odbc.dll(1.0.3300)

6.      代碼中增加引用 using Microsoft.Data.Odbc;

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Drawing;

using System.Linq;   //vs2005好像沒(méi)有這個(gè)命名空間，在c#2008下測試自動(dòng)生成的

using System.Text;

using System.Windows.Forms;

using Microsoft.Data.Odbc;

namespace mysql

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

        private void Form1_Load(object sender, EventArgs e)

        {

            string MyConString = "DRIVER={MySQL ODBC 3.51 Driver};" +

                                 "SERVER=localhost;" +

                                 "DATABASE=inv;" +

                                 "UID=root;" +

                                 "PASSWORD=831025;" +

                                 "OPTION=3";

            OdbcConnection MyConnection = new OdbcConnection(MyConString);

            MyConnection.Open();

            Console.WriteLine("\n success, connected successfully !\n");

            string query = "insert into test values( 'hello', 'lucas', 'liu')";

            OdbcCommand cmd = new OdbcCommand(query, MyConnection);

            //處理異常：插入重復記錄有異常

try{

   cmd.ExecuteNonQuery();

}

catch(Exception ex){

                 Console.WriteLine("record duplicate.");

}finally{

                 cmd.Dispose();

}

//***********************用read方法讀數據到textbox**********************

            string tmp1 = null;

            string tmp2 = null;

            string tmp3 = null;

            query = "select * from test ";

            OdbcCommand cmd2 = new OdbcCommand(query, MyConnection);

            OdbcDataReader reader = cmd2.ExecuteReader();

            while (reader.Read())

            {

                tmp1 = reader[0].ToString();

                tmp2 = reader[1].ToString();

                tmp3 = reader[2].ToString();

            }

            this.textBox1.Text = tmp1 + " " + tmp2 + " " + tmp3;

            */

//************************用datagridview控件顯示數據表**************************

string MyConString = "DRIVER={MySQL ODBC 3.51 Driver};" +

                                 "SERVER=localhost;" +

                                 "DATABASE=inv;" +

                                 "UID=root;" +

                                 "PASSWORD=831025;" +

                                 "OPTION=3";

          OdbcConnection MyConnection = new OdbcConnection(MyConString);

OdbcDataAdapter oda = new OdbcDataAdapter("select * from customer ", MyConnection);

DataSet ds = new DataSet();

          oda.Fill(ds, "employee");
          this.dataGridView1.DataSource = ds.Tables["employee"];

*/

           MyConnection.Close();

        }

    }

}
