AutoMapper不会将ViewModel映射到Model

Question

I have ViewModel:

public class EmployeeViewModel
    {
        public Developer Developer { get; set; }
        public Administrator Administrator { get; set; }
    }

and Model:

public class Developer 
        {
            //some stuff
        }

I'm trying to map it in the Action:

public ActionResult AddDeveloper(EmployeeViewModel employee)
        {
            AutoMapper.Mapper.CreateMap<EmployeeViewModel, Developer>();
            Developer developer = AutoMapper.Mapper.Map<EmployeeViewModel, Developer>(employee);
            .......
        }

after that developer variable has no values for parameters that employee has. Could you please help me?

You are simply trying to map a class to a property effectively. You need to explicitly tell how to bring both element onto the same level, for example:

public ActionResult AddDeveloper(EmployeeViewModel employee)
        {
            AutoMapper.Mapper.CreateMap<EmployeeViewModel, Developer>()
                      .ForMember(destination => destination, option => option.MapFrom(source => source.Developer));
            Developer developer = AutoMapper.Mapper.Map<EmployeeViewModel, Developer>(employee);
        }

Now the same thing should work. I have never tried doing the mapping at that level, I suspect you may have to try using the "AfterMap" function like here: https://stackoverflow.com/a/4750709/3002953 .
