dynamic to concrete type with automapper

Question

I do a post with an anonymous type on an WebApi controller in the body I have this new { Firstname = "AA", Lastname = "BB"}

[HttpPost]
public IHttpActionResult Post([FromBody]dynamic person)
{
}

When I hit the controller, person is not null and I can see the the properties with their data.

In the controller I'd like convert the dynamic type to my concrete type Person

public class Person
{
    public string Firstname { get; set; }
    public string Lastname { get; set; }
}

I tried with Mapper.Initialize(cfg => cfg.CreateMap<dynamic, Person>());

When I do this

var person = Mapper.Map<dynamic, Person>(source);

All the properties of person are null.

Any idea ?

Thanks,

According to the documentation, instead of...

    var person = Mapper.Map<dynamic, Person>(source);

...just use...

    var person = Mapper.Map<Person>(source);

Full example:

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public override string ToString() { return FirstName + " " + LastName; }
}

//Main
Mapper.Initialize( cfg => {} );
dynamic source = new ExpandoObject();
source.FirstName = "Hello";
source.LastName = "World";
var person = Mapper.Map<Person>(source);

Console.WriteLine("GetType()= '{0}' ToString()= '{1}'", person.GetType().Name, person);

Output:

GetType()= 'Person' ToString()= 'Hello World'
