c# - 如何关闭 Entity Framework 5 的复数表创建？

Question

我正在尝试使用 Entity Framework 5。第一个问题是 EF 会自动创建表。我试图通过包括 dbModelBuilder.Conventions.Remove<PluralizingTableNameConvention>() .第二个问题是这样的错误

The model backing the 'CountryContext' context has changed since the database was created. Consider using Code First Migrations to update the database.

我尝试通过 dbModelBuilder.Conventions.Remove<IncludeMetadataConvention>(); 修复它但没有意义。下一个数据访问层:

Table(Name = "tblCountries")]
public class Country
{
     [Column(Name = "id", IsDbGenerated = true, IsPrimaryKey = true)]
    public int Id {get;set;}

    [Column(Name = "name")]
    public string Name {get;set;}
}

public class CountryContext:DbContext
{
    public CountryContext(string connStr):base(connStr)
    {
    }

    public DbSet<Country> TblCountries { get; set; }

    protected override void OnModelCreating(DbModelBuilder dbModelBuilder)
    {
        dbModelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
        dbModelBuilder.Conventions.Remove<IncludeMetadataConvention>();
    }
}

    public class CountryDal:BaseDal
{
   public int CheckIsExist(Country country)
    {
        int id = 0;
        using (var context = new CountryContext(ConnectionString))
        {
            var first = context.TblCountries.FirstOrDefault(el => el.Name == country.Name);
            if (first != null)
            {
                id = first.Id;
            }
        }
        return id;
    }
    }

附加信息:VS 2012，框架 4.5， Entity Framework 5.0.0.0对于 EF 4，它工作完美(没有 OnModelCreating 方法)。

Answer 1

您可以在 OnModelCreating 方法中编写此代码:

modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
