Asp.Net 2.0 操作mysql 数据基类(读取,删除,插入,更新)

mysql for C#数据源驱动

第一步:请引用此压缩包中的MySql.Data.dll. 放在(bin)目录中

第二步:web.config 中的连接字符串:

<add key="mysqlconn" value="server=IP地址;database=数据库名;uid=登陆帐号;pwd=登陆密码;"></add>

第三步:

using System;
using System.Data;
using System.Configuration;
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.Types;
using MySql.Data.MySqlClient;
