Json forming using c#

Hi My json structure is like this

{
  "OutputParam": [
    {
      "param1": "John",
      "param2": "Doe",
      "param3": "BT",
      "param4": [
        {
          "subparam1": "00002",
          "subparam2": "True",
          "subparam3": "-",
          "subparam4": "-",
          "subparam5": "data goes here"
        },
        {
          "subparam1": "00003",
          "subparam2": "True",
          "subparam3": "-",
          "subparam4": "-",
          "subparam5": "data goes here"
        },
        {
          "subparam1": "00004",
          "subparam2": "False",
          "subparam3": "111",
          "subparam4": "message",
          "subparam5": "-"
        }
      ]
    }
  ]
}

and the classes which I get from http://json2csharp.com/ is as follows 

public class Param4
{
    public string subparam1 { get; set; }
    public string subparam2 { get; set; }
    public string subparam3 { get; set; }
    public string subparam4 { get; set; }
    public string subparam5 { get; set; }
}

public class OutputParam
{
    public string param1 { get; set; }
    public string param2 { get; set; }
    public string param3 { get; set; }
    public List<Param4> param4 { get; set; }
}

public class RootObject
{
    public List<OutputParam> OutputParam { get; set; }
}

now the issues is I want to pass above Json as API output in c# API, I tried list and var but so far not able to return the above mentioned Json, can any one help or at least give a direction?

Here is small sample of code that can help you 

public RootObject1 Get(int id)
    {
        RootObject1 rt = new RootObject1();
        OutputParam pr = new OutputParam();
        Param4 cr = new Param4();
        rt.OutputParam = new List<OutputParam>();
        pr.Param4= new List<Param4>();
        pr.Param1= "AB";
        rt.OutputParam = new List<OutputParam>();
        cr.Param6 = "aceee";
        pr.Param4.Add(cr);

        rt.OutputParam.Add(pr);
        return rt;
    }

your webservice c# prolly return an xml whith your json as string in? this is the default

so you have different choice

go for xml or add this line to your methode

[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]

If you want to return as per your example using Web API a method such as

public RootObject GetRootObject()
{
   return new RootObject();
}

Would do it, assuming the request to the API asked for JSON in the content negotiation - the web api will derserialise your object into JSON auto-magically
