asp.net管理mysql数据库的小工具

来源:网络时间:2011-06-21 16:04:34

  在 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。
