我对 MySql 和 Entity Framework Code First 有疑问。

我在 web.config.xml 中的连接字符串

<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; }
}

我的类(class):

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

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

我的 Controller

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？

最佳答案

将所有评论收集到答案中。

在port=3306后加分号；并检查您的 mysql 监听端口(也许是 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" />
