EntityFramework 6.0< Code First > 连接 Mysql数据库

一,安装:

1、开发环境: VS2013与EF6

2、Mysql数据库为:Mysql Server 6.0

3、安装:Mysql for Visual Studio 1.1.1

下载位置:https://cdn.mysql.com/Downloads/MySQLInstaller/mysql-visualstudio-plugin-1.1.1.msi

4、安装 Mysql Connector/Net 6.8.3 GA

下载位置:http://dev.mysql.com/downloads/connector/net/

二,引用dll:

1、采用Nuget安装EF6.0.2;

2、采用Nuget安装MySql.Data.Entity.EF6

注意:要采用Nuget进行安装,否则可能会缺少相应的dll或者是配置信息

三、配置 web.config或app.config

1、将entitframework节点替代为:

<entityFramework codeConfigurationType="MySql.Data.Entity.MySqlEFConfiguration, MySql.Data.Entity.EF6">
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework"/>
    <providers>
        <provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6" />
        <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    </providers>
</entityFramework>

2、添加 ConnectionString节点:

<connectionStrings>

<add name="MyContext" connectionString="Data Source=localhost;port=3306;Initial Catalog=数据库名称;user id=Mysql的登录用户名;password=Mysql server密码;" providerName="MySql.Data.MySqlClient"/>

</connectionStrings>

四、测试C#代码

using System.Data.Entity;

namespace StudyEF{
    public class MyContext : DbContext{
    public MyContext() : base("name=MyContext"){
    }
    public DbSet<Data> Datas {
        get; set; 
    }
  }
  public class Data{
     public int Id { 
        get; set; 
     }
     public string Name { 
        get; set; 
    }
}
  class Program{
     static void Main(string[] args){
     Database.SetInitializer(new DropCreateDatabaseAlways<MyContext>());
     var context = new MyContext();
     context.Datas.Add(new Data{Name="EF6-MySql"});
     context.SaveChanges();
     }
  }
}

五、在Mysql的cmd下查询:
