先,我们到官方下载mysql-connector-net-5.5
Mysql的connector/net5.0下载地址:
http://dev.mysql.com/get/Downloads/Connector-Net/mysql-connector-net-5.0.6.zip/from/pick
安装好以后,
点属性,然后点查找目标,点向上一层目录,找到Binaries.NET 2.0,然后将这个文件复制到你的工程目录下,一般这样的DLL文件会保存到bin目录下.
在 代码页里输入using Mysql.Data.MysqlClient;然后再在Page_Load函数里写MysqlConnection,在单词写到一半时提示就出来了,下 面的就不用写了吧?都已经出现”代码智能完成了”,随便写一段代码试试就可以了,和Sqlserver完全相似.
下面提供两段代码供参考,一个代码页
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using MySql.Data.MySqlClient;
public partial class Default2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string query = "select * from guestbook";
MySqlConnection myConnection = new MySqlConnection("server=localhost;user id=root;password=;database=guestbook");
MySqlCommand myCommand=new MySqlCommand(query,myConnection);
myConnection.Open();
myCommand.ExecuteNonQuery();
MySqlDataReader myDataReader = myCommand.ExecuteReader();
string bookres="";
while (myDataReader.Read()==true)
{
bookres+=myDataReader["id"];
bookres+=myDataReader["user"];
bookres += myDataReader["pass"];
}
myDataReader.Close();
myConnection.Close();
lb1.Text = bookres;
}
}
1、下载MySQL数据库,地址:http://www.mysql.com/,大小只有几十个兆而已,安装很方便,接提示即可。
2、 MySQL安装后默认是没有客户端工具的(像SQLServer的企业管理器,查询分析器等),只是一个服务器存储数据,为了方便你要再下载一个客户端工 具,有很多,推荐使用SQL Manager for MySQL,简洁小巧,功能也强大。下载:http://www.sqlmanager.net/en/products/mysql/manager /download
3、ASP.NET连接MySQL需要一个组件(.net本身不提供访问MySQL的驱 动)MySQL.Data.Dll,此为官方提供(纯C#开发,开源噢),有多个版本选择,采用的数据访问模式为ADO.NET,跟asp.net访问 sqlserver很像,非常简单。下载(里边有个demo):http://dev.mysql.com/downloads/connector /net/5.1.html
c#连接MySql数据库的两种方法
测试环境:Windows XP + MySql 5.0.24 + Visual C# 2008 Exdivss Edition

一、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″);
this.dataGrid1.DataSource = ds.Tables[“table1″];
conn.Close();
}
}
}
二、通过ODBC访问mysql数据库:
参考:http://www.microsoft.com/china/community/Column/63.mspx
1. 安装Microsoft ODBC.net:我安装的是mysql-connector-odbc-3.51.22-win32.msi
2. 安装MDAC 2.7或者更高版本:我安装的是mdac_typ.exe 2.7简体中文版
3. 安装MySQL的ODBC驱动程序:我安装的是 odbc_net.msi
4. 管理工具 -> 数据源ODBC ?>配置DSN…
5. 解决方案管理中添加引用 Microsoft.Data.Odbc.dll(1.0.3300)
6. 代码中增加引用 using Microsoft.Data.Odbc;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Linq; //vs2005好像没有这个命名空间,在c#2008下测试自动生成的
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);
//处理异常:插入重复记录有异常
try{
cmd.ExecuteNonQuery();
}
catch(Exception ex){
Console.WriteLine(“record duplicate.”);
}finally{
cmd.Dispose();
}
//***********************用read方法读数据到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控件显示数据表**************************
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();
}
}
}
