c#连接MySql数据库的两种方法

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”);

this.dataGrid1.DataSource = ds.Tables[“table1”];
conn.Close();

}

}
}

2、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();
}
}
}
