方法一:
使用CoreLab推出的MYSQL访问组件,面向.NET 安装完成后,引用命名空间:CoreLab.MySql; 使用命令编译时:csc /r:CoreLab.MySql.dll test.cs 以下为访问MYSQL数据库实例 编译指令:csc /r:CoreLab.MySql.dll /r:MySql.Data.dll test.cs using System; using System.Net; using System.Text; using CoreLab.MySql; using System.Data.Odbc; using MySql.Data.MySqlClient; class ConnectMySql { public void Connect_CoreLab() { string constr = "User Id=root;Host=localhost;Database=qing;password=qing"; MySqlConnection mycn = new MySqlConnection(constr); mycn.Open(); MySqlCommand mycm = new MySqlCommand("select * from shop",mycn); MySqlDataReader msdr = mycm.ExecuteReader(); while(msdr.Read()) { if (msdr.HasRows) { Console.WriteLine(msdr.GetString(0)); } } msdr.Close(); mycn.Close(); } public void Connect_Odbc() { //string MyConString ="DSN=MySQL;UID=root;PWD=qing"; string MyConString = "DRIVER={MySQL ODBC 3.51 Driver};" + "SERVER=localhost;" + "DATABASE=test;" + "UID=root;" + "PASSWORD=qing;" + "OPTION=3"; OdbcConnection MyConn = new OdbcConnection(MyConString); MyConn.Open(); OdbcCommand mycm = new OdbcCommand("select * from hello",MyConn); OdbcDataReader msdr = mycm.ExecuteReader(); while(msdr.Read()) { if (msdr.HasRows) { Console.WriteLine(msdr.GetString(0)); } } msdr.Close(); MyConn.Close(); } public void Connect_Net() { string myConnectionString = "Database=test;Data Source=localhost;User Id=root;Password=qing"; MySqlConnection mycn = new MySqlConnection(myConnectionString); mycn.Open(); MySqlCommand mycm = new MySqlCommand("select * from hello",mycn); MySqlDataReader msdr = mycm.ExecuteReader(); while(msdr.Read()) { if (msdr.HasRows) { Console.WriteLine(msdr.GetString(0)); } } msdr.Close(); mycn.Close(); } public static void Main() { ConnectMySql ms = new ConnectMySql(); ms.Connect_CoreLab(); ms.Connect_Odbc(); Connect_Net(); } } 方法二: 使用MYSQL推出的MySQL Connector/Net is an ADO.NET driver for MySQL 该组件为MYSQL为ADO.NET访问MYSQL数据库设计的.NET访问组件。 安装完成该组件后,引用命名空间MySql.Data.MySqlClient; 使用命令行编译时:csc /r:MySql.Data.dll test.cs 方法三: 通过ODBC访问MYSQL数据库 访问前要先下载两个组件:odbc.net和MYSQL的ODBC驱动(MySQL Connector/ODBC (MyODBC) driver)目前为3.51版 安装完成后,即可通过ODBC访问MYSQL数据库 |
