使用Automapper进行自定义映射，其中目标中的字段是源中两个字段的串联

Question

I think that the title already quite explains the problem. I have a source type:

public class Employee
{
    public string Name { get; set; }
    public string DateOfBirth { get; set; }
    public string srcImage { get; set; }
    public string Email { get; set; }
    public string Role { get; set; }
}

and

public class EmployeeViewModel
{
    public string Name { get; set; }
    public string Surname { get; set; }
    public string DateOfBirth { get; set; }
    public string Email { get; set; }
    public string Role { get; set; }
}

I want to use automapper to convert from EmployeeViewModel to Employee and the name of Employee is the concatenation of name and surname in EmployeeViewModel.

May you kindly explain me how to set the MapperConfiguration? Thanks!

Try this:

Mapper.CreateMap<EmployeeViewModel, Employee>()
                        .ForMember(d => d.Name, d => d.MapFrom(x => string.Format("{0}{1}", x.Name, x.Surname)));
