让Entity Framework支持MySql数据库

转载地址：http://www.cnblogs.com/wintersun/archive/2010/12/12/1903861.html    

Entity Framework 4.0 也可以支持大名鼎鼎的MySql,这篇POST将向展示如何实现EF+MySql数据库的结构.首先,你必须下载 MySQL Connector/NET 6.3.5 ,也就是.net下连接MySql数据库的驱动程序. 还是像以往一样的,增加一个Entity data model:

 

将下面选择DataSource, 选择MySQL database 做为数据源.

接下来几步和以前一样,选择要Mapping的Tables:

好了,让我们来测试一下:

   1:  using(var context = new MySqlEntities())

   2:  {    var myEvents = from e in context.Events            

   3:          from a in e.Attendees                    

   4:            where a.Person.FirstName == "Gunnar" &&                  

   5:            a.Person.LastName == "Peipman"                

   6:      select e;     Console.WriteLine("My events: ");  

   7:     foreach(var e in myEvents)   

   8:     {      

   9:       Console.WriteLine(e.Title);  

  10:     }

  11:  }
