Desearalising JSON with arrays in arrays

I've spent a while trying to work out how to desterilise this JSON file and get each products
ID,NAME,COLLECTION COST, AND WEATHER ITS ON OFFER
Im currently attempting this with Newtonsoft.Json in a C# class.
could someone please point me in the right direction.
Many thanks
for the JSON text visit:

How do I get UNIQUE categories from all documents in CosmosDB?

I have millions of documents in CosmosDB using SQL API, and I need to find the unique categories from all documents.
The documents looks like follows, you can see the categories array just under the description, I dont care in what order they are I just need to know all the unique ones from all documents in the collection, I need this so that later on I can create queries on the categories but thats a later question I first need to get them all out so I know what all the possible options are, but I am unable to figure out the query to do this so that I get only the category names.

Please see my test, it could get all the unique categories names.
Sample document:
[
{
"id": "1",
"locales": [
{
"categories": [
"Women",
"clothing",
"tops"
]
}
]
},
{
"id": "2",
"locales": [
{
"categories": [
"Men",
"test",
"tops"
]
}
]
}
]
SQL:
SELECT distinct cat FROM c
join l in c.locales
join cat in l.categories
Output:
[
{
"cat": "Women"
},
{
"cat": "clothing"
},
{
"cat": "tops"
},
{
"cat": "Men"
},
{
"cat": "test"
}
]
If you don't want to case sensitive,just use LOWER function in sql.
SELECT distinct Lower(cat) FROM c
join l in c.locales
join cat in l.categories
If you want to get ["Women","clothing","tops","Men","test"], it can't be parsed as an array in single sql directly, you could use stored procedure to parse the output array.
For example, add below code in stored procedure.
var returnArray = [];
for(var i=0 ;i<array.size;i++){
returnArray.push(array[i].value)
}
return returnArray;

Generic method to convert a flat JSON array to nested JSON

I have a JSON object as below
[
{
"Id": 7,
"Name": "Colocation Folder",
"ParentId": 1,
"depth": 0
},
{
"Id": 8,
"Name": "CoLo Real Estate",
"ParentId": 7,
"depth": 1
},
{
"Id": 10,
"Name": "CoLo: Burst",
"ParentId": 7,
"depth": 1
},
{
"Id": 34,
"Name": "CoLo Dedicated Bandwidth",
"ParentId": 7,
"depth": 1
},
{
"Id": 10035,
"Name": "Infrastructure as a Service",
"ParentId": 7,
"depth": 1
},
{
"Id": 10037,
"Name": "Software as a Service",
"ParentId": 7,
"depth": 1
},
{
"Id": 10038,
"Name": "IaaS Component Upgrade",
"ParentId": 7,
"depth": 1
},
{
"Id": 668,
"Name": "CoLo Misc Folder",
"ParentId": 7,
"depth": 1
},
{
"Id": 758,
"Name": "CoLo: Conduit Fee",
"ParentId": 668,
"depth": 2
},
{
"Id": 765,
"Name": "CoLo: Private VLAN",
"ParentId": 668,
"depth": 2
}
]
The Id and ParentId fields show the relation between the items. I need to make it as a nested JSON using C#.
Since there will be many such models, I don't want to create individual classes for each model. Is there a generic approach in C# that will take a flat JSON array, take the ID and ParentId fields as input and then return me a nested JSON with all other fields in the array as well? For example, I am looking for an output of nested JSON as below:
[
{
"Id": 7,
"Name": "Colocation Folder",
"items": [
{
"Id": 8,
"Name": "CoLo Real Estate",
"ParentId": 7
},
{
"Id": 10,
"Name": "CoLo: Burst",
"ParentId": 7
},
{
"Id": 34,
"Name": "CoLo Dedicated Bandwidth",
"ParentId": 7
},
{
"Id": 10035,
"Name": "Infrastructure as a Service",
"ParentId": 7
},
{
"Id": 10037,
"Name": "Software as a Service",
"ParentId": 7
},
{
"Id": 10038,
"Name": "IaaS Component Upgrade",
"ParentId": 7
},
{
"Id": 668,
"Name": "CoLo Misc Folder",
"ParentId": 7,
"items": [
{
"Id": 758,
"Name": "CoLo: Conduit Fee",
"ParentId": 668
},
{
"Id": 765,
"Name": "CoLo: Private VLAN",
"ParentId": 668
}
]
}
]
}
]

If you use Json.Net, you can do this conversion in a generic way using the LINQ-to-JSON API (JObjects). The idea is to parse the JSON array and add all the individual items to a dictionary keyed by Id. Then, loop over the dictionary items, and for each one, try to look up the parent. If the parent is found, add the item to the parent's items array (creating it if needed). Otherwise, add the item to the root array. Along the way, remove the depth property from each item, since you don't seem to want that in the output. Lastly, just dump the root array to string to get the final result.
var dict = JArray.Parse(json)
.Children<JObject>()
.ToDictionary(jo => (string)jo["Id"], jo => new JObject(jo));
var root = new JArray();
foreach (JObject obj in dict.Values)
{
JObject parent;
string parentId = (string)obj["ParentId"];
if (parentId != null && dict.TryGetValue(parentId, out parent))
{
JArray items = (JArray)parent["items"];
if (items == null)
{
items = new JArray();
parent.Add("items", items);
}
items.Add(obj);
}
else
{
root.Add(obj);
}
JProperty depth = obj.Property("depth");
if (depth != null) depth.Remove();
}
Console.WriteLine(root.ToString());
Fiddle: https://dotnetfiddle.net/Buza6T

You can use a dynamic object with JSON.Net like so to detect your properties dynamically then you could build a new json object with the desired nesting:
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
dynamic d = JArray.Parse(stringy);
foreach(var ob in d)
{
if(ob.ParentID != ob.Id)
{
string debug = "oh snapple, it's a child object";
}
}

Please help ,

I'm using Newtonsoft 8.0.2 and I was able to get what you are asking with this.
string input = File.ReadAllText("C:\\Public\\input.json");
dynamic collection = JsonConvert.DeserializeObject(input);
foreach (var dataItem in collection.data)
{
dynamic comments = dataItem.comments;
foreach (dynamic comment in comments.data)
{
string text = comment.text;
}
}
What you were missing was that you did not iterate through each comment object under your item.

As You can see, object "data" is an Array, and further we can see object "tags", which is also array. how can I check number elements array of array in C#? i tried like this:
JArray items = (JArray)jsonData["data[0].tags"];
int length = items.Count;
but it doesn't work. I parse JSON like this:
dynamic jsonData = JsonConvert.DeserializeObject<dynamic>(JSON_string);

var token = JToken.Parse(str);
var data = token.Value<JArray>("data");
var tags = data[0].Value<JArray>("tags");
var count = tags.Count;
You can also use a JsonPath:
var token = JToken.Parse(str);
var count = token.SelectTokens("$.data[0].tags[*]").Count();
