C#连接MySql数据库的方法

用MySQLDriverCS连接MySQL数据库

先下载和安装MySQLDriverCS，地址：

/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 ponentModel;

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", "crm", "root", "qaz").AsString);

conn.Open();

//以下两行很重要，不然中文显示为乱码

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");

DataGridView1.DataSource = ds.Tables["table1"];

conn.Close();

}

}

}
