在Asp.net 中，可以通过MySql.Data.dll来操作mysql数据库，写法跟操作SQL数据库类似，下面是相关的例子。
一、打开mysql数据库：
MySqlConnection DBConn = new MySqlConnection();
string connString ="Host=127.0.0.1;UserName=root;Password=root;Database=test;Port=3306;CharSet=utf8;Allow Zero Datetime=true";
DBConn.ConnectionString = connString;
DBConn.Open();
二、执行sql命令
string sqlstr="select * from test";
MySqlCommand command = new MySqlCommand(sqlstr, DBConn);
command.ExecuteNonQuery();
从上面可以看出，用法跟操作SQL数据库的SqlConnection、SqlCommand非常相似，下面我这里有一个完整的例子来实现对mysql数据库进行管理，包括浏览表结构和数据、查询-修改-插入-删除数据，导出数据和表结构等，供大家参考和互相学习。代码写得不规范，还请大家指正。
