下载链接here
2.添加MySql.Data库。
右击 项目—>添加—>引用—>扩展—>选择MySql.Data(第一个)
3.配置webconfig.xml
在configration结点下添加结点：

<connectionStrings>        <add name="connection" connectionString="Data Source=localhost;Initial Catalog=database_name;Persist Security Info=True;User ID=root;Password=123456" providerName="MySql.Data.MySqlClient"/>    </connectionStrings>

4.代码中：(label1用来显示调试信息)

using MySql.Data;using MySql.Data.MySqlClient;protected void Page_Load(object sender, EventArgs e)    {        MySqlConnection connection = new MySqlConnection(System.Web.Configuration.WebConfigurationManager.ConnectionStrings["Con"]            .ConnectionString.ToString());        try        {            connection.Open();            this.Label1.Text = "连接数据库成功!";        }        catch(Exception err)        {            Label1.Text = "连接数据库失败！";            Label1.Text += err.Message;        }        finally        {            connection.Close();        }    }
