修改ASP.NET Web API反序列化过程

Question

I created a Webserver based on the OWIN / Katana. Currently I have problems about understanding the JSON deserialization process...

This is the simple POST-Method:

public IHttpActionResult Post([FromBody] Person person) {
// do some stuff
return Ok();
}

Now the question: Why are all Getters of the Model called by default, also if there are attributed as "JsonIgnore" or no "DataMember".

Model:

[DataContract]
public class Person
{
    private string firstName;

    //This property-getter should not be called
    public string FirstName{
        get {
            return firstName;
        }
        set {
            firstName = value;
        }
    }

    //This property-getter should be called
    [DataMember]
    public string LastName { get;set; }
}

Is is possible to change this process?

Solved.

I detected that the getter is called during Web API model validator (see class "DefaultBodyModelValidator")
