[英]EF Core - Entity Mapping Configuration
In previous versions of EF, you could configure all of your entity maps on the DbContext like this :- 在早期版本的EF中,您可以像这样在DbContext上配置所有实体映射:-
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Configurations.AddFromAssembly(typeof(MyDbContext).Assembly);
base.OnModelCreating(modelBuilder);
}
However in the latest EF Core it seems you have to add each mapping individually like this :- 但是,在最新的EF Core中,您似乎必须像这样单独添加每个映射:-
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.ApplyConfiguration(new UserMap());
modelBuilder.ApplyConfiguration(new AddressMap());
base.OnModelCreating(modelBuilder);
}
Is there no similar way of add Entity Maps, as this is tedious. 没有类似的添加实体贴图的方法,因为这很繁琐。
This do the same of the AddFromAssembly
of EF6: 这样做与AddFromAssembly
相同:
var configurations = typeof(MyDbContext).Assembly.GetTypes()
.Where(t => t.BaseType != null && t.BaseType.IsGenericType && t.BaseType.GetGenericTypeDefinition() == typeof(System.Data.Entity.ModelConfiguration.EntityTypeConfiguration<>));
foreach (var config in configurations)
{
dynamic instance = System.Activator.CreateInstance(config);
modelBuilder.Configurations.Add(instance);
}
