实体框架填写虚拟属性

Question

I'm using EF 6 with code first, repository pattern + UOW pattern.

I have ca method that will return all items of a specific entity.

Ex: UnitOfWork.Customers.GetAllCustomers() that will return an IQueryable

In the Customer model I have a virtual property called Adress that will be filled in at runtime

public virtual Address Address { get; set; }

Whenever in my controller I call the GetAllCustomers, all information are there except the Address property that is null.

Any ideas how to return also the address ?

Answer 1

See Entity Framework Loading Related Entities .

Either eager-load using .Include(c => c.Address) or enable lazy loading so EF will do the work for you.

Answer 2

The Lazy Loading, load the entity only if Its accessed for the first time. You should load it manually:

.Include(c => c.Address)

OR

.Include("Address")
