mysql-connector-net-6.3.8.msi
(2)安装mysql-connector-net
然后直接在Windows *** 作系统安装 mysql-connector-net-6.3.8.msi
(3)封装数据库访问组件DbConnectionMySQL
方法一:
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
下载地址: http://dev.mysql.com/downloads/connector/net/1.0.html
方法二:
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
方法三:
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 Systemusing 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=rootHost=localhostDatabase=qingpassword=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=MySQLUID=rootPWD=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=testData Source=localhostUser Id=rootPassword=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()
}
}
