Filter parsed JSON object

I am making rest call and receving following JSON response:
{
"issues": [{
"id": "250271",
"self": "KeyUrl1",
"key": "Key-8622",
"fields": {
"attachment": [{
"self": "AttachmentUrl1",
"id": "106198",
"filename": "export.htm"
}
],
"customfield_11041": "Test"
}
},
{
"id": "250272",
"self": "KeyUrl2",
"key": "Key-8621",
"fields": {
"attachment": [{
"self": "AttachmentUrl2",
"id": "106199",
"filename": "lmn.htm"
}
],
"customfield_11041": "Test"
}
},
]
}
I parsed it using NewtonSoft Json to JObject.
var jObject = JObject.Parse(response);
Further I am trying to filter such records where either attachment is missing or none of the attachments contain filename like "export".
Following is the code I have written, ideally it should result in just 1 record in the records object, however its returning both the objects.
var issues = jObject["issues"] as JArray;
var records = issues.Where(x => !x["fields"]["attachment"].Any() || !x["fields"]["attachment"].Any(y => y["filename"].Contains("export")));
Need help to figure out whats going wrong.
Here's fiddle link - https://dotnetfiddle.net/AVyIHr

The problem is that you're calling Contains("export") on the result of y["filename"], which isn't a string - it's a JToken. You need to convert to a string first, to use the form of Contains that you're expecting.
Additionally, you can get rid of the first condition - an issue with no attachments doesn't have any attachments with "export" filename anyway.
That leaves this:
var records = issues
.Where(x => !x["fields"]["attachment"].Any(y => ((string) y["filename"]).Contains("export")))
.ToList();
You may well find it's simpler to deserialize to a class, however - that will reduce the risk of typos and the risk of this sort of conversion error. If you deserialized to a List<Issue> you'd have a condition of:
x => !x.Fields.Attachments.Any(y => y.Filename.Contains("export"))
... which I think is rather cleaner.

var records = issues.Where(x => !x["fields"]["attachment"].Any() || !x["fields"]["attachment"].Any(y => y["filename"].ToString().Contains("export"))).ToList();
Add .ToString() will resolve the issue.

Remove property name from Json when its array

I am converting XML to JSON.
Input:
<emp
id="17377"/>
<CustomerList>
<Customer
id="67149"/>
<Customer id="64260"/>
</CustomerList>
OutPut:
"emp": {
"id": "17377"
},
"CustomerList": {
"Customer": [
{
"id": "67149"
},
{
"id": "64260"
}
]
}
But I need the below output. But I can not remove <Customer from <CustomerList> in the input. Also Please note that I need accept dynamic name
of array input. But always i want to remove the inner property name to be removed. in this example its Customer.But I may get MarkList->Mark then I need to remove remove Mark, etc.,:
"emp": {
"id": "17377"
},
"CustomerList": [
{
"id": "67149"
},
{
"id": "64260"
}
]
Is this possible please.
I use below code to convert XML to Json:
var xml = new XmlDocument();
xml.XmlResolver = null;
xml.LoadXml(richTextBox1.Text);
var jsonText = JsonConvert.SerializeXmlNode(xml,Newtonsoft.Json.Formatting.Indented);
Note:
One solution would be find the char "[" and remove before "[" and after "{".

This is not possible, as it is simply trying to change to JSON scheme in which it was orignally built.
what you can do, is use JObject to change the value of customer to feet your needs:
JObject rss = JObject.Parse(json);
JObject customers = rss.SelectToken("CustomerList");
customers ["Customer"] = newValue;
This is the snippet, modify this in your code to feet your needs.

Accesing child value in JSON

How can i acces the first item id?
using (var http = new HttpClient())
{
var res = JArray.Parse(await http.GetStringAsync("http://api.champion.gg/champion/Gragas?api_key=????").ConfigureAwait(false));
^^^^^^ // Also tried with JObject instead of JArray, both don't work
var champion = (Uri.EscapeUriString(res[0]["items"][0]["mostGames"][0]["items"][0]["id"].ToString()));
Console.WriteLine(champion); // ^ [0] here because the JSON starts with an [
}
Example JSON result (made it smaller because the original JSON is over 21500 characters, made sure its valid with https://jsonlint.com, here is the original JSON response: https://hastebin.com/sacikozano.json)
[{
"key": "Gragas",
"role": "Jungle",
"overallPosition": {
"change": 1,
"position": 13
},
"items": {
"mostGames": {
"items": [{
"id": 1402,
"name": "Enchantment: Runic Echoes"
},
{
"id": 3158,
"name": "Ionian Boots of Lucidity"
},
{
"id": 3025,
"name": "Iceborn Gauntlet"
},
{
"id": 3065,
"name": "Spirit Visage"
},
{
"id": 3742,
"name": "Dead Man's Plate"
},
{
"id": 3026,
"name": "Guardian Angel"
}
],
"winPercent": 50.45,
"games": 300
}
}
}]
With JArray i get the following error: Accessed JObject values with invalid key value: 0. Object property name expected.
With JObject i get the following error: Error reading JObject from JsonReader. Current JsonReader item is not an object: StartArray. Path '', line 1, position 1.
Thanks in advance, i hope i explained it well

It should be:
var champion = (Uri.EscapeUriString(res[0]["items"]["mostGames"]["items"][0]["id"].ToString()));
The outermost "items" property has a single object as its value, not an array, so [0] is not needed in ["items"][0]. Similarly "mostGames" has a single object value so the [0] is not needed in ["mostGames"][0].
Sample fiddle.
Note that if "items" is sometimes an array of objects, but sometimes is a single object instead of an array of one object, you can introduce the following extension method:
public static class JsonExtensions
{
public static IEnumerable<JToken> AsArray(this JToken item)
{
if (item is JArray)
return (JArray)item;
return new[] { item };
}
}
And do:
var champion = (Uri.EscapeUriString(res[0]["items"].AsArray().First()["mostGames"]["items"][0]["id"].ToString()));

Deserialize Facebook Json result in C#

I'm getting the following Json format string as a result from a Facebook graph search request :
{
"data": [
{
"name": "Event A",
"start_time": "2013-11-08T19:00:00+0200",
"end_time": "2013-11-10T00:00:00+0200",
"timezone": "Europe/Bucharest",
"id": "232252355126"
},
{
"name": "Event B",
"start_time": "2013-11-08T13:00:00+0200",
"end_time": "2013-11-09T16:00:00+0200",
"timezone": "Europe/Bucharest",
"location": "Bucharest",
"id": "414334343426"
},
{
"name": "Event C",
"start_time": "2013-10-30T18:30:00+0200",
"timezone": "Europe/Bucharest",
"location": "Bucharest",
"id": "44315995273"
}
],
"paging": {
"previous": "https://graph.facebook.com/search?limit=3&type=event&q=Bucharest&since=1383930000&__paging_token=22251255126",
"next": "https://graph.facebook.com/search?limit=3&type=event&q=Bucharest&until=1383150600&__paging_token=44115995273"
}
}
I'm encountering some errors while trying to retrieve data from this JSON. I've tried with
dynamic jsonData = await facebookClient.GetTaskAsync(string.Format("https://graph.facebook.com/search?q={0}&type=event&limit={1}&offset={2}", locationKeyword, limit, offset));
dynamic result = JsonConvert.DeserializeObject(jsonData.ToString());
Some answers direct me to use JavaScriptSerializer but I don't have the namespace for that class, as I'm using API for developing Windows 8 Apps.
I can't manage how to get the events as somehow from data object.
I tried accessing the values in the immediate windows in VS as result.data but it's not working.
I search on how to make this but most answers seem to say to create a class in which the json data will fit.
Can't I achieve this with dynamic? (something like result.data.name, result.paging.previous etc)

I have done this exact thing before, except I converted into an XML, My Example:
(1 - JavaScript) var finalStr = JSON.stringify(facebookString)
(2 - ASP.NET) JsonConvert.DeserializeXmlNode("{\"root\":" + received_json + "}","root");

I managed at last to access the members...
To access name for example, or start_time, I did the following :
dynamic jsonData = await facebookClient.GetTaskAsync(string.Format("https://graph.facebook.com/search?q={0}&type=event&limit={1}&offset={2}", locationKeyword, limit, offset));
var result = JObject.Parse(jsonData.ToString());
var array = new JArray(result["data"]);
var a = array[0];
string name = (string) a.SelectToken("name");
var date = (DateTime?) a.SelectToken("start_time");
There might be better implementations but this one worked in my case. I posted it, in case it might be of help to others seeing this post.
Best wishes.

JSON nested array

Lets say i have the following JSON
{
"data": [
{
"from": {
"name": "aaa bbb",
},
"actions": [
{
"name": "Comment",
"link": "http://...
},
{
"name": "Like",
"link": "http://.."
}
],
},
And i have
JSONObject wallData = helper.Get("/me/feed");
if (wallData != null)
{
var data = wallData.Dictionary["data"];
List<JSONObject> wallPosts = data.Array.ToList<JSONObject>();
}
foreach (Facebook.JSONObject wallItem in wallPosts)
{ ... }
Which stores me whole feed into wallData and 'data' object into wallPosts.
So then i can access the wallItem.Dictionary["from"].Dictionary["name"], and i get "aaa bbb".
But i can't get inside the actions array
The wallItem.Dictionary["actions"].Dictionary["name"] doesn't work.
Any idea

You need to do something like wallItem.Dictionary["actions"][0].Dictionary["name"] because "actions" is an array.

On a different note...its neater if u directly into a class...like this
var jSerializer = new JavaScriptSerializer();
var jsonObject = jSerializer.Deserialize<DataObject>(json);
The DataObject will be a class which emulates ur JSON data in a strongly typed class. Depending on the size of ur Json you will not have to use a lot of strings in your code.
