asp.net連接mysql數據褲的連接文件該如何寫？

連接MYSQL數據庫的方法及示例方法壹：使用MYSQL推出的MySQL Connector/Net is an ADO.NET driver for MySQL該組件為MYSQL為ADO.NET訪問MYSQL數據庫設計的.NET訪問組件。安裝完成該組件後，引用命名空間MySql.Data.MySqlClient;使用命令行編譯時：csc /r:MySql.Data.dll test.cs方法二：通過ODBC訪問MYSQL數據庫訪問前要先下載兩個組件：odbc.net和MYSQL的ODBC驅動(MySQL Connector/ODBC (MyODBC) driver)目前為3.51版安裝完成後，即可通過ODBC訪問MYSQL數據庫方法三：使用CoreLab推出的MYSQL訪問組件，面向.NET安裝完成後，引用命名空間：CoreLab.MySql;使用命令編譯時：csc /r:CoreLab.MySql.dll test.cs以下為訪問MYSQL數據庫實例編譯指令：csc /r:CoreLab.MySql.dll /r:MySql.Data.dll test.csusing 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 c; 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 MyC; string MyC + "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 myC; 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();}}
