EF4 Code First和EF6 Code First链接mysql的方法

1、首先需要下载安装.Net的Mysql驱动

下载地址如下：

2、配置Web.Config

EF6:

配置链接字符串

<connectionStrings>
     <add name="sqldata" connectionString="server=地址;Character Set=utf8;User Id=用户名;password=密码;Persist Security Info=True;database=数据库名称" providerName="MySql.Data.MySqlClient" />
</connectionStrings>

配置驱动

<system.data>
    <DbProviderFactories>
      <remove invariant="MySql.Data.MySqlClient"></remove><!--预防Machine.config中已经配置了MySql.Data.MySqlClient-->
      <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient"
      description=".Net Framework Data Provider for MySQL"
      type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data,
        Version=6.9.5.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
    </DbProviderFactories>
</system.data>

 配置EF6的驱动

<entityFramework>
   <providers>
      <provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6" />
   </providers>
</entityFramework>

EF4.1:

配置链接字符串

<connectionStrings>
     <add name="sqldata" connectionString="server=地址;Character Set=utf8;User Id=用户名;password=密码;Persist Security Info=True;database=数据库名称" providerName="MySql.Data.MySqlClient" />
</connectionStrings>

配置驱动

<system.data>
    <DbProviderFactories>
      <remove invariant="MySql.Data.MySqlClient"></remove><!--预防Machine.config中已经配置了MySql.Data.MySqlClient-->
      <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient"
      description=".Net Framework Data Provider for MySQL"
      type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data,
        Version=6.9.5.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
    </DbProviderFactories>
</system.data>

配置完这些就可以使用Mysql了  ！
