Get JSON child element value - c#

I'm trying to get spuCode from this JSON:
{
"msg": "success",
"state": 0,
"data": {
"result": {
"spuCode": "541426110605",
"productName": "纯黑色斜纹面料铅笔裤百搭大码小脚裤弹力打底裤休闲裤子女",
"productTitle": null,
"spuImgs": [

"https://cbu01.alicdn.com/img/ibank/2016/793/372/3617273397_1742354982.jpg",

],
"upAndDown": 1,
"updateTime": 1537096913958,
"platform": "ALIBABA",
"skus": [
{
"skuCode": "3488434133172",
"sellPrice": 3900,
"sellableNum": 905,
"productProps": [
{
"propId": 7590793702270582000,
"valueId": 5453504708925905000,
"propName": "颜色",
"valueName": "纯黑色(相同面料)"
},
{
"propId": 9000005669393888000,
"valueId": 6217370164147047000,
"propName": "尺码",
"valueName": "XXL"
}
],
As you can see there is Parent data with child result so I added this code:
string sp = "";
var obj = Newtonsoft.Json.Linq.JObject.Parse(responseFromServer);
foreach (JObject child in obj["data"]["result"].OfType<JObject>())
{
sp = child["spuCode"].ToString();
MessageBox.Show(sp);
}
But it never triggers MessageBox.Show what am I missing here?

result isn't an array so there is no need for foreach.
Try SelectToken method like this:
var spuCode = (string)obj.SelectToken("data.result.spuCode");

Filter data from deep json child

the JSON below is taken from other post. My issue is I know the id and I want to find out where is it located. Eg, I got ID 19006 and I want to get Folder2. How am I going to do this.
{
"data": {
"id": 0,
"name": "",
"childFolders": [{
"id": 19002,
"name": "Locker",
"childFolders": [{
"id": 19003,
"name": "Folder1",
"childFolders": [],
"childComponents": [{
"id": 19005,
"name": "route1",
"state": "STOPPED",
"type": "ROUTE"
}]
}, {
"id": 19004,
"name": "Folder2",
"childFolders": [],
"childComponents": [{
"id": 19008,
"name": "comm1",
"state": "STOPPED",
"type": "COMMUNICATION_POINT"
}, {
"id": 19006,
"name": "route2",
"state": "STOPPED",
"type": "ROUTE"
}, {
"id": 19007,
"name": "route3",
"state": "STOPPED",
"type": "ROUTE"
}]
}],
"childComponents": []
}],
"childComponents": []
},
"error": null
}
I write code now it is like this:
var json = GetJsonString();
var model = GetJsonModel(json);
var folderName = GetName(model.data, 19006);
I chekced and code is correct. folderName is Folder2
And the recursive code:
private string GetName(Data data, int searchValue)
{
var folderName = data.name;
foreach (var item in data.childComponents)
{
if (item.id == searchValue)
{
return folderName;
}
}
if (data.childFolders.Length > 0)
{
foreach (var item in data.childFolders)
{
var folderName1 = GetName(item, searchValue);
if (folderName1 != null)
{
return folderName1;
}
}
}
return null;
}
Your model is like this:
EDIT:
I parse Json like this.
return JsonSerializer.Deserialize<YourJson>(test);

Recursively create JSON in C# without losing the JProperties from the first iteration

Here, I am trying to create a JSON using using Newtonsoft.Json; libraries. I came up with a function which partially does my job and when the same function is called, my previous data on the JObject is lost. I am new to this items JProperty, JObject, JArray, JToken however managed to come up with this code.
The parent is initiated in the function itself and when the function is recursively called its initiated and cleaned up again. So I added another JObject head. Making it more complicated.
string statment = "(Entity.Country = 'USA' AND Entity.ShortName = 'Adele' AND (Entity.CIFNumber = '12345' OR Statement.StatementYear = '2015'))";
public static JObject ConvertToJsonObject(string text)
{
JObject parent = new JObject();
string bracketContents = getWhatsInsideBrackets(text);
parent.Add(new JProperty("operator", ReturnOperator(text)));
parent.Add(new JProperty("rules"));
string[] operators = splitWithOperator(bracketContents);
List<JObject> req = new List<JObject>();
for (int i = 0; i < splitWithOperator(bracketContents).Length; i++)
{
if (!checkIfBracketsExists(operators[i].Trim()))
{
req.Add(GetEachCondition(operators, i));
}
else if (checkIfBracketsExists(operators[i]))
{
parent["rules"] = new JArray(ConvertToJsonObject(operators[i]));
head = parent;
parent["rules"] = (ConvertToJsonObject(operators[i]));
}
}
parent["rules"] = new JArray(req);
head["rules"] = parent;
return parent;
}
I am trying to achieve this JSON output: (Only trying to achieve the key, value of DataSetCommonQuery, dont worry about the other keys on the json)
{
"context": {
"wfId": "00000000-0000-0000-0000-000000000000",

JSON Enum list deserialization

I have JSON Like below
{
"_id": "0FEB6D4B-8DA5-4143-B926-11A7AE4F3B12",
"device": {
"name": "test",
"family": "test"
},
"channels": [
{
"mcl": 33,
"vtype": "FLOAT",
"category": " Current"
},
{
"tag": "OperationMode",
"vtype": "BYTE",
"enums": [
{
"0": "Off"
},
{
"1": "On"
},
{
"2": "ByPass"
}
]
}
]
}
I am using Json.net to deserialize the JSON to C# object. I am not able to manage to convert the enum list. I validated if this is valid JSON. I tried with custom converter & string converter but reader value is null. Any quick help appreciated.
JObject jR = JObject.Parse(YourJsonString);
JArray oR = (JArray)jR["channels"];
JArray jA = (JArray)oR[1]["enums"];
foreach (var item in jA)
{
Dictionary<string,string> enums = Newtonsoft.Json.JsonConvert.DeserializeObject<Dictionary<string,string>>(item.ToString());
foreach (var en in enums)
{
Console.WriteLine(en.Value);
}
}

Json Searching Data Structures

This is my Data Structure and I'm trying to access it with simpleJason, through unity/c#, I have accidentally gotten the right data here and there, and otherwise gotten completely empty arrays, I'd like to know if my JSON file is improperly setup for my data structure, or if the parser is somehow falling though, or not properly matching what I'm looking for.
JSON File:
{
"categories": [
{
"name" : "entertainment",
"projects": [
{
"name": "Awards",
"description": "Awards Shows",
"credits": [
"Lead Engineer - Dave Jones",
"VFX Supervisor - John Adrian",
"CG Supervisor - Evan Klein"
],
"meta": [
"awards",
"show",
"stars",
"red carpet"
],
"assets": [
{
"name": "Screen Actors Guild Awards",
"filename": "SAG_Awards.mp4",
"icon": "sag.png",
"stereo": false,
"meta": [
"Screen",
"Actors",
"Guild"
]
},
{
"name": "No Awards",
"filename": "No_SAG_Awards.mp4",
"icon": "no_sag.png",
"stereo": false,
"meta": [
"Screen",
"Actors",
"Guild"
]
},
{
"name": "None Awds",
"filename": "None_SAG_Awards.mp4",
"icon": "none_sag.png",
"stereo": false,
"meta": [
"Screen",
"Actors",
"Guild"
]
}
]
}
]
}
]
}
This is the struct :
private struct jsonAsset {
public string category;
public string project;
public string description;
public string[] credits;
public string[] meta;
public string asset;
public FileInfo file;
public FileInfo icon;
public bool stereo;
public bool overUnder;
};
This is the function:
jsonAsset LoadSceneDataFromJSON(FileInfo jsonFile)
{
jsonAsset asset = new jsonAsset();
Debug.Log("Processing : " + jsonFile);
// Parse File for Data
var N = JSON.Parse(File.ReadAllText(jsonFile.FullName));
var cat_arr = N["categories"].AsArray;
asset.category = N["categories"]["name"].Value;
Debug.Log(N["categories"]["projects"]["assets"]["filename"].Value);
foreach (JSONNode n in cat_arr)
{
asset.project = n["name"].Value;
// Credits
var proj_credits = n["credits"].AsArray;
foreach (JSONNode pc in proj_credits)
{
asset.credits[asset.credits.Length] = pc["credits"].Value;
}
// Project Meta
var proj_meta = n["meta"].AsArray;
foreach (JSONNode pm in proj_meta)
{
asset.meta[asset.meta.Length] = pm["meta"].Value;
}
// Project Array
var proj_arr = n["projects"].AsArray;
foreach (JSONNode nn in proj_arr)
{
var asset_arr = nn["assets"].AsArray;
asset.asset = nn["assets"]["name"].Value;
foreach (JSONNode nnn in asset_arr)
{
asset.asset = nnn["name"].Value;
asset.file = new FileInfo(m_dir + nnn["filename"].Value);
asset.icon = new FileInfo(m_dir + nnn["icon"].Value);
var asset_meta = nnn["meta"].AsArray;
foreach (JSONNode am in asset_meta)
{
asset.meta[asset.meta.Length] = am.Value;
}
}
}
}
return asset;
}
You are treating projects as an object instead of an array.
I dont know what JSON library you are using to give you guidance, but something like this will probably work:
N["categories"]["projects"][0]["assets"]["filename"].Value

How can I add values to a NewtonSoft JObect?

I am usin NewtonSoft JSON.Net and I have a JObject that I need to add and remove items to and form it dynamicly from my code.
If this is my json:
{
"IgnoredInterests": [
{
"Id": 1,
"Name": "test"
},
{
"Id": 2,
"Name": "test"
}
]
}
I need to be able to add more items or even remove items from it via code.
How can I add this to the JObject:
{
"Id": 3,
"Name": "test"
}
And even remove:
{
"Id": 2,
"Name": "test"
}
I appreciate your help...
string json = #"{
'IgnoredInterests': [
{
'Id': 1,
'Name': 'test'
},
{
'Id': 2,
'Name': 'test'
}
]
}";
JObject obj = JObject.Parse(json);
string json_add = #"{
'Id': 3,
'Name': 'test'
}";
JArray array = obj.GetValue("IgnoredInterests") as JArray;
JObject obj_add = JObject.Parse(json_add);
array.Add(obj_add);
foreach (JObject item in array.Children())
{
if (item.GetValue("Id").ToString() == "2")
{
array.Remove(item);
break;
}
}
