How to add a new JProperty to a JSON based on path? - c#

There is a large JSON file (about a thousand lines). The task is to update existing JProperties, or add new JProperties in a specific location in the structure. The location of the new texts are based on the JToken.Path property. For example, this is the start of the JSON:
"JonSnow": {
"Direwolf": {
"Name": "Ghost",
"Color": "White",
}
}
"DanaerysTargaryen": {
"Dragons": {
"Dragon1": {
"Name": "Drogon",
}
}
"Hair": {
"Color": "White"
}
}
Now the JSON must be updated using a given list of JToken paths and the corresponding values.
The first possibility is, the JProperty corresponding to the path might already exist, in which case the value needs to be updated. I am already successfully implementing this with JToken.Replace().
The second possibility is, the JProperty does not exist yet and needs to be added. For example, I need to add "DanaerysTargaryen.Dragons.Dragon1.Color" with the value "Black".
I know I can use the JSON.Net Add() method, but to use this only the final child token of the path can be missing from the JSON. For example, I can use
JObject ObjToUpdate= JObject.Parse(jsonText);
JObject Dragon = ObjToUpdate["DanaerysTargaryen"]["Dragons"]["Dragon1"] as JObject;
Dragon.Add("Color", "Black"));
But what about if I need to add "JonSnow.Weapon.Type" with the value "Longsword"? Because "Weapon" does not exist yet as a JProperty, and it needs to be added along with "Type" : "Longsword". With each path, it is unknown how much of the path already exists in the JSON. How can this be parameterised?
// from outside source: Dictionary<string, string> PathBasedDict
// key: Jtoken.Path (example: "JonSnow.Weapon.Type")
// value: new text to be added (example: "Longsword")
foreach(KeyValuePair entry in PathBasedDict)
{
string path = entry.Key;
string newText = entry.Value;
if (ObjToUpdate.SelectToken(path) != null)
{ ObjToUpdate.SelectToken(path).Replace(newText); }
else AddToJson(path, newText);
}
What should AddToJson() look like? Iterating through the entire path and checking each possible JProperty to see if it exists, and then adding the rest underneath, seems very cumbersome. Is there a better way to do this? Any Json.NET tricks I am unaware of? I am not even sure how the iteration could be parameterised.

Based on first approach from Heretic Monkey's answer, here is an extension method:
public static class JObjectExtensions
{
/// <summary>
/// Replaces value based on path. New object tokens are created for missing parts of the given path.
/// </summary>
/// <param name="self">Instance to update</param>
/// <param name="path">Dot delimited path of the new value. E.g. 'foo.bar'</param>
/// <param name="value">Value to set.</param>
public static void ReplaceNested(this JObject self, string path, JToken value)
{
if (self is null)
throw new ArgumentNullException(nameof(self));
if (string.IsNullOrEmpty(path))
throw new ArgumentException("Path cannot be null or empty", nameof(path));
var pathParts = path.Split('.');
JToken currentNode = self;
for (int i = 0; i < pathParts.Length; i++)
{
var pathPart = pathParts[i];
var isLast = i == pathParts.Length - 1;
var partNode = currentNode.SelectToken(pathPart);
if (partNode is null)
{
var nodeToAdd = isLast ? value : new JObject();
((JObject)currentNode).Add(pathPart, nodeToAdd);
currentNode = currentNode.SelectToken(pathPart);
}
else
{
currentNode = partNode;
if (isLast)
currentNode.Replace(value);
}
}
}
}

There are a few ways of going about this. Here are two of them.
To go along with your existing code, split the path by '.', then iterate over them. If the path is not there, create it with Add. Otherwise, if we're on the last part of the path, just add the value.
var json = JObject.Parse(#"{""DanaerysTargaryen"":{""Dragons"":{""Dragon1"":{""Name"": ""Drogon""}},""Hair"": {""Color"": ""White""}}}");
var toAdd = "DanaerysTargaryen.Dragons.Dragon1.Color";
var valueToAdd = "Black";
var pathParts = toAdd.Split('.');
JToken node = json;
for (int i = 0; i < pathParts.Length; i++)
{
var pathPart = pathParts[i];
var partNode = node.SelectToken(pathPart);
if (partNode == null && i < pathParts.Length - 1)
{
((JObject)node).Add(pathPart, new JObject());
partNode = node.SelectToken(pathPart);
}
else if (partNode == null && i == pathParts.Length - 1)
{
((JObject)node).Add(pathPart, valueToAdd);
partNode = node.SelectToken(pathPart);
}
node = partNode;
}
Console.WriteLine(json.ToString());
(Example on dotnetfiddle.net)
Otherwise, you could create a separate JObject that represents the node(s) you want to add, then merge them.
var json = JObject.Parse(#"{""DanaerysTargaryen"":{""Dragons"":{""Dragon1"":{""Name"": ""Drogon""}},""Hair"": {""Color"": ""White""}}}");
var toMerge = #"{""DanaerysTargaryen"":{""Dragons"":{""Dragon1"":{""Color"":""Black""}}}}";
var jsonToMerge = JObject.Parse(toMerge);
json.Merge(jsonToMerge);
Console.WriteLine(json.ToString());

Iterate IDictionary<string, string> with dynamic nested JSON as value in C#

My application receives Kafka messages that contain a Dictionary<string,string> as one of the properties, and its values could be a nested (however dynamic) json string, and I need to iterate through this unknown json. I am struggling to find a logic and even the best data structure to do this iteration.
Examples of the dictionary (mocked data):
//could have complex nested json string as value
"reward":"{
'xp':'200',
'gp':'150',
'loot':'{
'item':'sword',
'rarity': 'low'
}'
}",
"achievement":"win_match"
// while other messages might be simple
"type":"generic_xp",
"percent":"100",
"status":"complete"
Serialized version of a real message:
"{\"player_stats\":\"{\\\"assist\\\":0,\\\"deaths\\\":0,\\\"kills\\\":0,\\\"team_index\\\":2}\",\"round_attr\":\"{\\\"max_player_count\\\":4,\\\"rdur\\\":0,\\\"round\\\":1,\\\"team_player_count\\\":{\\\"team_1\\\":1,\\\"team_2\\\":0},\\\"team_score\\\":0}\",\"custom\":\"{\\\"armor\\\":\\\"armor_pickup_lv2\\\",\\\"balance\\\":550,\\\"helmet\\\":\\\"helmet_pickup_lv2\\\",\\\"misc\\\":[{\\\"count\\\":48,\\\"item_id\\\":\\\"shotgun\\\"},{\\\"count\\\":120,\\\"item_id\\\":\\\"bullet\\\"},{\\\"count\\\":2,\\\"item_id\\\":\\\"health_pickup_combo_small\\\"},{\\\"count\\\":2,\\\"item_id\\\":\\\"health_pickup_health_small\\\"}],\\\"weapon_1\\\":\\\"mp_weapon_semipistol\\\",\\\"weapon_2\\\":\\\"mp_weapon_shotgun_pistol\\\"}\",\"gdur\":\"0\"}"
To complicate even more
Create a model class is not an option because this json is completely dynamic
Flatting the dictionary is not possible because the json may have duplicated key names, but under different hierarchy
I cant request to change the Kafka message
What I am trying to do
The end user will define rules that I need to check if I find a match. For instance, a rule could be reward.xp == 200 or reward.loot.rarity == high or status == complete. These rules will be defined by the user so it cant be hardcoded, however I can decide with data structure to use to save them. So for each Kafka message, I have to iterate through that dictionary and try to find a match with the rules.
What I have tried
I ve tried JsonConvert.Deserialize to object, dynamic, ExpandoObject and none could handle the nested json hierarchy. They just got the 1st level correct. Same result with JObject.Parse as well.
Parse the JSON using whatever parser you like (I used Newtonsoft.Json).
Then recursively visit the hierarchy and copy each property to a flat list using the full path to each property value as a key. You can then iterate that flat list.
Edit: Comment requested supporting arrays, so this version does.

Finding all identifiers containing part of the token

I know I can get a string from resources using
Resources.GetIdentifier(token, "string", ctx.ApplicationContext.PackageName)
(sorry, this is in C#, it's part of a Xamarin.Android project).
I know that if my elements are called foo_1, foo_2, foo_3, then I can iterate and grab the strings using something like
var myList = new List<string>();
for(var i = 0; i < 4; ++i)
{
var id = AppContent.GetIdentifier(token + i.ToString(), "string", "package_name");
if (id != 0)
myList.Add(AppContext.GetString(id));
}
My issue is that my token names all begin with "posn." (the posn can denote the position of anything, so you can have "posn.left_arm" and "posn.brokenose"). I want to be able to add to the list of posn elements, so I can't really store a list of the parts after the period. I can't use a string-array for this either (specific reason means I can't do this).
Is there a way that I can use something akin to "posn.*" in the getidentifer call to return the ids?
You can use some reflection foo to get what you want. It is not pretty at all but it works. The reflection stuff is based on https://gist.github.com/atsushieno/4e66da6e492dfb6c1dd0
private List<string> _stringNames;
private IEnumerable<int> GetIdentifiers(string contains)
{
if (_stringNames == null)
{
var eass = Assembly.GetExecutingAssembly();
Func<Assembly, Type> f = ass =>
ass.GetCustomAttributes(typeof(ResourceDesignerAttribute), true)
.OfType<ResourceDesignerAttribute>()
.Where(ca => ca.IsApplication)
.Select(ca => ass.GetType(ca.FullName))
.FirstOrDefault(ty => ty != null);
var t = f(eass) ??
AppDomain.CurrentDomain.GetAssemblies().Select(ass => f(ass)).FirstOrDefault(ty => ty != null);
if (t != null)
{
var strings = t.GetNestedTypes().FirstOrDefault(n => n.Name == "String");
if (strings != null)
{
var fields = strings.GetFields();
_stringNames = new List<string>();
foreach (var field in fields)
{
_stringNames.Add(field.Name);
}
}
}
}
if (_stringNames != null)
{
var names = _stringNames.Where(s => s.Contains(contains));
foreach (var name in names)
{
yield return Resources.GetIdentifier(name, "string", ComponentName.PackageName);
}
}
}
Then somewhere in your Activity you could do:
var ids = GetIdentifiers("action").ToList();
That will give you all the String Resources, which contain the string action.

Identifying that a property's value is an array

I have a JSON file:
{
"abn":"63119059513",
"acn":"119059513",
"business_structure":"Private Company",
"ngr_number":"1231231",
"cbh_number":"1231231",
"main_name":"Brickworks Building Products Pty Ltd",
"trading_name":"Brickworks",
"other_trading_names":"Austral Bricks",
"directors":[
{
"ID":"12114",
"ae_forms_filled_in_ID":"22739",
"name":"John Smith",
"dob":"1983-10-29",
"address_line_1":"123 Fake Street",
"address_line_2":"",
"address_line_city":"Fakeland",
"address_line_postcode":"2000",
"address_line_state":"New South Wales",
"address_line_country":"Australia",
"order_extract_id":null,
"director_found":null,
"drivers_lic":"",
"home_mortgage":"",
"phone":"",
"mobile":"",
"director_email":"",
"director_title":"Mr",
"director_position":"Director",
"dir_pdf_url":null
}
],
}
I want to determine if the value of any property has a structure of an array. The best I can come up with so far is:
StreamReader streamrr = new StreamReader("C:\\temp\\agfarm_example_udate.json", Encoding.UTF8);
string JSON = streamrr.ReadToEnd();
JObject CWFile = JObject.Parse(JSON);
foreach (JProperty property in CWFile.Properties())
{
// Do something
if (property.Value.ToString().Contains("["))
{
// Do something with the array
JArray items = (JArray)CWFile[property.Name];
foreach (JObject o in items.Children<JObject>())
{
foreach (JProperty p in o.Properties())
{
// Do something
}
}
}
}
To determine whether or not a property value has an array, I used the condition:
if (property.Value.ToString().Contains("["))
I'm just wondering if there is a better way of doing this check?
One way to do this is to check the JToken.Type property. Arrays are of type JTokenType.Array:
if (property.Value.Type == JTokenType.Array)
{
var items = (JArray)property.Value;
// Proceed as before.
}
Or, you can just try to cast to JArray:
if (property.Value is JArray)
{
var items = (JArray)property.Value;
// Proceed as before.
}
Both are preferable to checking property.Value.ToString().Contains("[") since a nested property might have an array value, thus causing a bracket to appear somewhere in the ToString() return.
If you want to recursively find every property with an array value, you can introduce an extension method:
public static class JsonExtensions
{
public static IEnumerable<JToken> WalkTokens(this JToken node)
{
if (node == null)
yield break;
yield return node;
foreach (var child in node.Children())
foreach (var childNode in child.WalkTokens())
yield return childNode;
}
}
And then do:
var CWFile = JToken.Parse(JSON)
var arrayProperties = CWFile.WalkTokens().OfType<JProperty>().Where(prop => prop.Value.Type == JTokenType.Array);
public void Traverse(string name, JToken j)
{
foreach (JToken token in j.AsJEnumerable())
if (token.Type == JTokenType.Object)
{
foreach (var pair in token as JObject)
{
string name_ = pair.Key;
JToken child = pair.Value;
Traverse(name, child);
}
}
else if (token.Type == JTokenType.Array) //an array property found
{
foreach (var child in token.Children())
Traverse(((JProperty)j).Name, child);
}
else if (token.Type == JTokenType.Property)
{
var property = token as JProperty; //current level property
Traverse(name, (JContainer)token);
}
else //current level property name & value
{
var nm = "";
var t = "";
if (j is JProperty)
{
nm = ((JProperty)j).Name;
t = Convert.ToString(((JProperty)j).Value);
}
t = Convert.ToString(token);
}
}
Call:
JSON = JObject.Parse(...);
Traverse("", JSON);
To parse and already parsed text for the same reason is not very wise :
if (property.Value.ToString().Contains("["))
Json structure is simple : objects, arrays, properties, values
http://www.json.org/
So array is a wellknown object for json and we are looking for it :
if (token.Type == JTokenType.Array) //an array property

C#. Set a member object value using reflection

I need your help with the following code below. Basically I have a class called "Job" which has some public fields. I'm passing to my method "ApplyFilter" two parameters "job_in" and "job_filters". First parameter contains actual data, and the second one has instructions (if any). I need to iterate through "job_in" object, read it's data, apply any instructions by reading "job_filters", modify data (if needed) and return it in a new "job_out" object. Everything works fine till i need to store my data in "job_out" object:
public class Job
{
public string job_id = "";
public string description = "";
public string address = "";
public string details = "";
}
...
private Job ApplyFilters(Job job_in, Job job_filters)
{
Type type = typeof(Job);
Job job_out = new Job();
FieldInfo[] fields = type.GetFields();
// iterate through all fields of Job class
for (int i = 0; i < fields.Length; i++)
{
List<string> filterslist = new List<string>();
string filters = (string)fields[i].GetValue(job_filters);
// if job_filters contaisn magic word "$" for the field, then do something with a field, otherwise just copy it to job_out object
if (filters.Contains("$"))
{
filters = filters.Substring(filters.IndexOf("$") + 1, filters.Length - filters.IndexOf("$") - 1);
// MessageBox.Show(filters);
// do sothing useful...
}
else
{
// this is my current field value
var str_value = fields[i].GetValue(job_in);
// this is my current filed name
var field_name = fields[i].Name;
// I got stuck here :(
// I need to save (copy) data "str_value" from job_in.field_name to job_out.field_name
// HELP!!!
}
}
return job_out;
}
Please help. I've seen a few samples by using properties, but i'm pretty sure it is possible to do the same with fields as well. Thanks!
Try this
public static void MapAllFields(object source, object dst)
{
System.Reflection.FieldInfo[] ps = source.GetType().GetFields();
foreach (var item in ps)
{
var o = item.GetValue(source);
var p = dst.GetType().GetField(item.Name);
if (p != null)
{
Type t = Nullable.GetUnderlyingType(p.FieldType) ?? p.FieldType;
object safeValue = (o == null) ? null : Convert.ChangeType(o, t);
p.SetValue(dst, safeValue);
}
}
}
fields[i].SetValue(job_out, str_value);
