MySql 和实体框架代码优先

Question

MySql 和 Entity Framework Code First 有问题。

web.config.xml 中的我的连接字符串

<add name="EntityContext" connectionString="Server=127.0.0.1; port=8080 Database=simple_crud; Uid=root; Pwd=;" providerName="MySql.Data.MySqlClient" />

我的背景：

public class EntityContext : DbContext
{
    public DbSet<Pessoa> Pessoas { get; set; }
}

我的班级：

[Table("pessoa")]
public class Pessoa
{
    [Key]
    [Column("Id")]
    public int Id { get; set; }

    [Column("Nome")]
    public string Nome { get; set; }
}

我的控制器

public EntityContext db = new EntityContext();

public ActionResult Index()
{
     List<Pessoa> pessoas = db.Pessoas.ToList(); // here is the error
     return View(pessoas);
}

所以，当我按 F5 时，我得到了这个：“输入字符串的格式不正确”。

我想念什么？

Answer 1

收集所有的 cmets 来回答。

在port=3306后加分号；并检查您的 mysql 监听端口（可能是 3306，mysql 默认？）。生成的连接字符串：

<add name="EntityContext" connectionString="Server=127.0.0.1; port=3306; Database=simple_crud; Uid=root; Pwd=;" providerName="MySql.Data.MySqlClient" />

Answer 2

MySql 默认端口是 3306；所以这里就不用多说了，

例如：

<add name="DefaultConnection" providerName="MySql.Data.MySqlClient" connectionString="SERVER=localhost;DATABASE=testdb;UID=test;PASSWORD=test123;" />
