I'm using an MVC 4 web API and asp.net web forms 4.0 to build a rest API. It's working great:
[HttpGet]
public HttpResponseMessage Me(string hash)
{
HttpResponseMessage httpResponseMessage;
List<Something> somethings = ...
httpResponseMessage = Request.CreateResponse(HttpStatusCode.OK,
new { result = true, somethings = somethings });
return httpResponseMessage;
}
Now I need to prevent some properties to be serialized. I know I can use some LINQ over the list and get only the properties I need, and generally it's a good approach, but in the present scenario the something object is too complex, and I need a different set of properties in different methods, so it's easier to mark, at runtime, each property to be ignored.
Is there a way to do that?

ASP.NET Web API uses Json.Net as default formatter, so if your application just only uses JSON as data format, you can use [JsonIgnore] to ignore property for serialization:
public class Foo
{
public int Id { get; set; }
public string Name { get; set; }
[JsonIgnore]
public List<Something> Somethings { get; set; }
}
But, this way does not support XML format. So, in case your application has to support XML format more (or only support XML), instead of using Json.Net, you should use [DataContract] which supports both JSON and XML:
[DataContract]
public class Foo
{
[DataMember]
public int Id { get; set; }
[DataMember]
public string Name { get; set; }
//Ignore by default
public List<Something> Somethings { get; set; }
}
