Conditionally serialize object members

Question

To serialize object to json we do as given below -

var json = new JavaScriptSerializer().Serialize(question);

then it returns given json data :-

{"que_desc":"devQuestion","qtype":3,"number_of_answer":3,"answers":[{"answer":"answer1","Question":null},{"answer":"answer2","Question":null},{"answer":"answer3","Question":null}]}

but I want to ignore "Question" property and need data as given below-

{
"que_desc": "This is Question details",
"qtype" : "1",
"number_of_answer" : "3",
"answers": [{"answer": "A", "is_default": "true"}, {"answer": "B"}, {"answer": "C"}]}

I want to ignore "Question" property while converting into json. so how we will conditionally serialize object members at run time??

Answer 1

You can use the Json.NET nuget and the [JsonIgnore] atribute at the que_desc property.

If you need more functionality, you can implemente de serialize methods by your self using Json.NET.

Answer 2

You could decorate the Question property with the [ScriptIgnore] attribute.

Supposing that Answer has a definition like the below:

public class Answer
{
    public string Answer { get; set; }

    public Question Question { get; set; }

    // rest
}

If you change it to the following:

public class Answer
{
    public string Answer { get; set; }

    [ScriptIgnore]
    public Question Question { get; set; }

    // rest 
}

You will get that you want.
