How to create Models in ASP.Net for multi level Json format?

Question

Problem Specification: Build a web api in asp.net to post multi level json formatted data.

Json Format:

{
  "InfoList:"[
    {
    "Name": " Sample String 1",
    "URL": " Sample String2",
    "Info":[
        {
            "ZIP": " Sample String3 "
            "status": "Sample String4"
        }
    ]
     }
   ]
}

I tried to solve this problem. My models are given bellow:

My Models:

public class Information : InfoList
    {
        public InfoList InfoList { get; set; }
    }

public class InfoList 
        {

            public string Name { get; set; }

            public string URL { get; set; }

            public Info info { get; set; }
        }

public class Info
    {
        public string ZIP{ get; set; }

        public string status { get; set; }

    }

Those models Generates this kind of Json Format:

{
  "InfoList": {
    "Name": "sample string 1",
    "URL": "sample string 2",
    "Info": {
      "ZIP": "sample string 1",
      "status": "sample string 2"
    }
  },
  "Name": "sample string 1",
  "URL": "sample string 2",
  "Info": {
    "ZIP": "sample string 1",
    "status": "sample string 2"
  }
}

I need those parentheses exactly like the problem specification.What to do? I am working with ASP.Net Web API controller.

Answer 1

You can use http://json2csharp.com/ online tool to create c# class from json data string. Just copy your json and get classes.

Answer 2

You just copy your JSON then create C# Class file. Then click Edit -> Paste Special -> Paste JSON as Classes. Thats it...

You need Visual Studio for this.

For more information please see below link

Valid JSON

{
    "InfoList":  {
        "Name": " Sample String 1",
        "URL": " Sample String2",
        "Info": [
            {
                "ZIP": " Sample String3 ",
                "status": "Sample String4"
            }
        ]
    }
}

So your class must be like this.

public class Rootobject
{
    public Infolist InfoList { get; set; }
}

public class Infolist
{
    public string Name { get; set; }
    public string URL { get; set; }
    public Info[] Info { get; set; }
}

public class Info
{
    public string ZIP { get; set; }
    public string status { get; set; }
}

Answer 3

You're inheriting Information from InfoList so naturally it will get the fields Name, URL etc. Remove the inheritance and change the InfoList and Info members into arrays or lists and you get what you want.

public class Information
{
    public InfoList[] InfoList { get; set; }
}

public class InfoList 
{
    public string Name { get; set; }
    public string URL { get; set; }
    public Info[] info { get; set; }
}

public class Info
{
    public string ZIP{ get; set; }
    public string status { get; set; }
}
