Entity Framework + AutoMapper ( Entity to DTO and DTO to Entity )
- by vbobruisk
Hello.
i got some problems using EF with AutoMapper. =/
for example :
i got 2 related entities ( Customers and Orders )
and theyr DTO classes :
class CustomerDTO
{
public string CustomerID {get;set;}
public string CustomerName {get;set;}
public IList< OrderDTO Orders {get;set;}
}
class OrderDTO
{
public string OrderID {get;set;}
public string OrderDetails {get;set;}
public CustomerDTO Customers {get;set;}
}
//when mapping Entity to DTO the code works
Customers cust = getCustomer(id);
Mapper.CreateMap< Customers, CustomerDTO ();
Mapper.CreateMap< Orders, OrderDTO ();
CustomerDTO custDTO = Mapper.Map(cust);
//but when i try to map back from DTO to Entity it fails with AutoMapperMappingException.
Mapper.Reset();
Mapper.CreateMap< CustomerDTO , Customers ();
Mapper.CreateMap< OrderDTO , Orders ();
Customers customerModel = Mapper.Map< CustomerDTO ,Customers (custDTO); // exception is thrown here
Am i doeing something wrong ?
Thanks in Advance !
