Extract data from complex JSON and convert into a single JObject

Question

I've got some complex JSON which looks something like this:

{
  "memberdetails": [
    {
      "id": 0,
      "label": "General Details",
      "visible": true,
      "properties": [
        {
          "label": "Address",
          "description": "Residential or Postal Address",
          "view": "textarea",
          "config": {},
          "hideLabel": false,
          "validation": {
            "mandatory": false,
            "pattern": null
          },
          "id": 0,
          "value": "test 1",
          "alias": "address",
          "editor": "Umbraco.TextboxMultiple",
          "visible": "true"
        },
        {
          "label": "State",
          "description": "State of residence",
          "view": "textbox",
          "config": {},
          "hideLabel": false,
          "validation": {
            "mandatory": false,
            "pattern": null
          },
          "id": 0,
          "value": "test 2",
          "alias": "state",
          "editor": "Umbraco.Textbox",
          "visible": "true"
        }
      ]
    },
    {
      "id": 1,
      "label": "Other Details",
      "visible": true,
      "properties": [
        {
          "label": "Address",
          "description": "Residential or Postal Address",
          "view": "textarea",
          "config": {},
          "hideLabel": false,
          "validation": {
            "mandatory": false,
            "pattern": null
          },
          "id": 0,
          "value": "test_otherdetails1 ",
          "alias": "aliastest",
          "editor": "Umbraco.TextboxMultiple",
          "visible": "true"
        },
        {
          "label": "State",
          "description": "State of residence",
          "view": "textbox",
          "config": {},
          "hideLabel": false,
          "validation": {
            "mandatory": false,
            "pattern": null
          },
          "id": 0,
          "value": "test_otherdetails2",
          "alias": "aliastest2",
          "editor": "Umbraco.Textbox",
          "visible": "true"
        }
      ]
    },
    {
      "id": 2,
      "label": " Details",
      "visible": true,
      "properties": [
        {
          "label": "Address",
          "description": "Residential or Postal Address",
          "view": "textarea",
          "config": {},
          "hideLabel": false,
          "validation": {
            "mandatory": false,
            "pattern": null
          },
          "id": 0,
          "value": " Details1",
          "alias": "Details1Test",
          "editor": "Umbraco.TextboxMultiple",
          "visible": "true"
        },
        {
          "label": "State",
          "description": "State of residence",
          "view": "textbox",
          "config": {},
          "hideLabel": false,
          "validation": {
            "mandatory": false,
            "pattern": null
          },
          "id": 0,
          "value": "Details2",
          "alias": "Details12est",
          "editor": "Umbraco.Textbox",
          "visible": "true"
        }
      ]
    }
  ]
}

I'm trying to extract the alias and value items from the JSON and put them into a single JObject like this:

{
  "address": "test 1",
  "state": "test 2",
  "aliastest": "test_otherdetails1 ",
  "aliastest2": "test_otherdetails2",
  "Details1Test": " Details1",
  "Details12est": "Details2"
}

Is there an easy way to do using Json.Net? Note the alias values will all be distinct in the actual JSON.

Answer 1

Yes, you can transform your JSON like this:

JObject obj = JObject.Parse(json);

JObject result = new JObject(
    obj["memberdetails"]
        .SelectMany(jt => jt["properties"])
        .Select(jt => new JProperty((string)jt["alias"],jt["value"]))
);

Console.WriteLine(result.ToString());
