AutoMapper: What's the difference between ForMember () and ForPath ()?

I am reading AutoMapper ReverseMap()

and I cannot understand the difference between ForMember()

and ForPath()

. The implementations have been described here . In my experience I have achieved c ForMember()

.

See the following code where I set up the reverse mapping:

public class Customer
{
    public string Surname { get; set; }
    public string Name { get; set; }
    public int Age { get; set; }
}
public class CustomerDto
{
    public string CustomerName { get; set; }
    public int Age { get; set; }
}

static void Main(string[] args)
{
    Mapper.Initialize(cfg =>
    {
        cfg.CreateMap<Customer, CustomerDto>()
           .ForMember(dist => dist.CustomerName, opt => opt.MapFrom(src => $"{src.Surname} {src.Name}"))
            .ReverseMap()
            .ForMember(dist => dist.Surname, opt => opt.MapFrom(src => src.CustomerName.Split(' ')[0]))
            .ForMember(dist => dist.Name, opt => opt.MapFrom(src => src.CustomerName.Split(' ')[1]));
    });

    // mapping Customer -> CustomerDto            
    //... 
    //

    // mapping CustomerDto -> Customer
    var customerDto = new CustomerDto
    {
        CustomerName = "Shakhabov Adam",
        Age = 31
    };
    var newCustomer = Mapper.Map<CustomerDto, Customer>(customerDto);
}

      

        
        
        
      

    

It works.

Question

Make Do ForMember

and ForPath

the same things or when I have to use ForPath()

over ForMember()

?
