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= ;UserName=root;PassWord=root;Database=test;Port= ;CharSet=utf ;Allow Zero Datetime=true ; DBConn ConnectionString = connString; DBConn Open(); 二执行sql命令 string sqlstr= select * from test ; MySqlCommand mand = new MySqlCommand(sqlstr DBConn); mand 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 <%@ Page Language= C# %> <%@ Import Namespace= System Data %> <%@ Import Namespace= System IO %> <%@ Import Namespace= System Text %> <%@ Import Namespace= MySql Data MySqlClient %> <!DOCTYPE PUBLIC //W C//DTD XHTML Transitional//EN transitional dtd > < xmlns= > <head runat= server > <title> MYSQL Manager (DoNet)</title> <style type= text/CSS > body tdfont: px Arial Tahoma;line height: px;
