asp.net管理mysql数据库的小工具

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。
