How to map single object to nested object
The below one is my entity.
class Employee
{
public string name { get; set; }
public string city_name { get; set; }
public string State_name { get; set; }
}
I want to map to
class Employee
{
public string Name;
public Location Location;
}
class Location
{
public string City;
public string State;
}
Please note that the property names are different. Can any one could help to map these using AutoMapper
ForPath
1.1 Create Profile
instance with inheriting from Profile
and put the configuration in the constructor.
1.1.1 Using ForPath to map nested property.
public class EmployeeProfile : Profile
{
public EmployeeProfile()
{
CreateMap<Employee, EmployeeDto>()
.ForPath(dest => dest.Location.City, opt => opt.MapFrom(src => src.city_name))
.ForPath(dest => dest.Location.State, opt => opt.MapFrom(src => src.State_name));
}
}
1.2 Adding profile to mapper configuration
public static void Main()
{
var config = new MapperConfiguration(cfg =>
{
cfg.AddProfile<EmployeeProfile>();
// Note: Demo program to use this configuration rather with EmployeeProfile
/*
cfg.CreateMap<Employee, EmployeeDto>()
.ForPath(dest => dest.Location.City, opt => opt.MapFrom(src => src.city_name))
.ForPath(dest => dest.Location.State, opt => opt.MapFrom(src => src.State_name));
*/
});
IMapper mapper = config.CreateMapper();
var employee = new Employee{name = "Mark", city_name = "City A", State_name = "State A"};
var employeeDto = mapper.Map<Employee, EmployeeDto>(employee);
}

AfterMap
2.1 Create Profile
instance with inheriting from Profile
and put the configuration in the constructor.
2.1.1 Using AfterMap to perform mapping nested property after map occurs.
public class EmployeeProfile : Profile
{
public EmployeeProfile()
{
CreateMap<Employee, EmployeeDto>()
.AfterMap((src, dest) => { dest.Location =
new Location {
City = src.city_name,
State = src.State_name
};
});
}
}
2.2 Adding profile to mapper configuration
public static void Main()
{
var config = new MapperConfiguration(cfg =>
{
cfg.AddProfile<EmployeeProfile>();
// Note: Demo program to use this configuration rather with EmployeeProfile
/*
cfg.CreateMap<Employee, EmployeeDto>()
.AfterMap((src, dest) => { dest.Location =
new Location {
City = src.city_name,
State = src.State_name
};
});
*/
});
IMapper mapper = config.CreateMapper();
var employee = new Employee{name = "Mark", city_name = "City A", State_name = "State A"};
var employeeDto = mapper.Map<Employee, EmployeeDto>(employee);
}
