I have a small problem with the WebApi.
Problem: If I want to post a model using JSON, I can add as many members I want, as long as the members defined in model are present.
Question: How can I trigger an exception, if an undefined member is present in my Json object. Is this achievable without a custom JsonConverter? What I'm looking for is a generic solution, not a convertion for every different model.
Example:
Model:
public class Person
{
[Required]
public string Name { get; set; }
}
Api Controller:
public class PersonController : ApiController
{
public HttpResponseMessage Post(Person person)
{
if (person != null)
{
if (ModelState.IsValid)
{
//do some stuff
return new HttpResponseMessage(HttpStatusCode.OK);
}
}
return new HttpResponseMessage(HttpStatusCode.BadRequest);
}
}
Json posts (body)
{"Name":"Joe"} --> valid
{"Name":"Joe","InvalidMember","test","Name","John"} --> also valid. In this case I want to trigger an Exception. Because if you look at it, it doesn't match my modeldefinition exactly.
