Question

I have the following two classes.

public class Foo
{
    public Bar Args { get; set; }

    public Foo()
    {
        Args = new Bar();
    }
}

public class Bar
{
    public string Name { get; set; }
    public int Age { get; set; }
}

When using:

var foo = new Foo();
foo.Args.Name = "Mikael";
foo.Args.Age = 12;
string o = JsonConvert.SerializeObject(foo);
Console.WriteLine(o);

I get the following json:

{"Args":{"Name":"Mikael","Age":12}}

This is somewhat correct i guess … but the other end I’m sending it to expects the Args to be an array, so it needs to look like this:

{"Args":[{"Name":"Mikael","Age":12}]}

Otherwise it sees the Args as a single object and not an array.

Can this be done with json.net ?

Answer 1

public class FooWrapper
{
    private Foo myfoo;

    public Bar[] Args { get { 
      Bar[] bar=new Bar[1]();
      bar[0]=myfoo.Bar;
      return bar;
    }}

    public FooWrapper(Foo foo)
    {
        myfoo=foo;
    }
}

var foo = new Foo();
foo.Args.Name = "Mikael";
foo.Args.Age = 12;
string o = JsonConvert.SerializeObject(new FooWrapper(foo));
Console.WriteLine(o);
