Sub Document operations in couchbase using .net sdk

Delete a specific node from all the available documents in a bucket
Is it possible to delete an element from the children array based on the Id from the below sample document using .NET SDK for Couchbase in C#?
i.e. I need to delete all the details of Id=100( delete the entire element in the children array).
I can achieve it using N1QL. N1QL performance is slow when there are thousands of document involved in couchbase
{
"results": [{
"tutorial": {
"type": "contact",
"title": "Mr.",
"fname": "Ian",
"lname": "Taylor",
"age": 56,
"email": "ian#gmail.com",
"children": [{
"Id": "100",
"Details": [{
"fname": "Abama",
"age": 17,
"gender": "F"
}]
},
{
"Id": "101",
"Details": [{
"fname": "Alex",

}]
}

Extract Items in Nested Json Array

How can I extract items from nested Json Array using Newtonsoft.Json functions or methods? I have a Json like this
{
"Bounds": {
"TextLength": 1379
},
"DocumentTypeName": "Invoice",
"DocumentTypeField": {
"Value": "Invoice",
"Confidence": 1
},
"Fields": [
{
"FieldId": "RPA.DocumentUnderstanding.Invoice.LineItems",
"FieldName": "Line Items",
"Values": [
{
"Components": [
{
"FieldId": "RPA.DocumentUnderstanding.Invoice.LineItems.Body",
"FieldName": "Body",
"Values": [
{
"Components": [
{
"FieldId": "RPA.DocumentUnderstanding.Invoice.LineItems.Item",
"FieldName": "Item",
"Values": [
{
"Components": [],
"Value": "Film 4C for the publication \"Racing World\" Visual: PNSP 02 05 Ref. 2004/021 Graphic designer honoraries 560010",
"Confidence": 0.962736368
}
]
},
{
"FieldId": "RPA.DocumentUnderstanding.Invoice.LineItems.UnitPrice",
"FieldName": "Unit Price",
"Values": [
{
"Components": [],
"Value": "400.00",
"Confidence": 0.9779528
}
]
}
],
"Confidence": 0.9432406
}]}],
"Confidence": 0.920952857}]}]}
and I want to extract the red highlighted fields from it.
Any help will be much appreciated.
Thanks

Since not deserializing is not a requirement you can do that. Just create C# object that has the exact same structure as your JSON and then do
var yourObject = JsonConvert.DeserializeObject<YourCSharpClassHere>(yourJsonString);
Then it's just a simple matter of getting the values
var fieldName = yourObject.Values[0].Components[0].Values[0].Components[0].FieldName

You can use JSON Query
Example
var fieldNames = o.SelectTokens("Values[*].Components[*].Values[*].Components[*].FieldName");

How to extract ID from the following JSON Object in C#?

I want to extract all IDs from the below object using c#.
in need of extracting a response value in a visual studio webtest.
The JSON is obtained using extract event.
{
"d": [
{
"__type": "QuestionZoneEditor.Entities.QuestionTag",
"Id": 2080,
"Name": "01",
"Items": [
"1a",
"1b",
"1c",
"1d"
]
},
{
"__type": "QuestionZoneEditor.Entities.QuestionTag",
"Id": 2081,
"Name": "02",
"Items": [
"2a(i)",
"2a(ii)",
"2b",
"2c"
]
},
{
"__type": "QuestionZoneEditor.Entities.QuestionTag",
"Id": 2082,
"Name": "03",
"Items": [
"3a",
"3b",
"3c"
]
}
}
]
}

Deserialize it to JObject after that take all JObject from the JArray and print the Id
var result = JsonConvert.DeserializeObject<JObject>(json);
foreach(JObject obj in result["d"])
{
Console.WriteLine(obj["Id"]);
}

Get Token in Json

I have a problem with this JSON to get the second level in JArray:
{
"Level1": {
"Level2": [{
"id": "Chart",
"Box": [{
"id": "1",
"value": "10"
},{
"id": "2",
"value": "20"
}]
}]
}
}
And I want to get completly the level 2 like Array in this way:
JArray contasdasd = _jsonMaster["Level1"]["Level2"] as JArray;
I get :
{
"id": "Chart",
"Box": [{
"id": "1",
"value": "10"
},{
"id": "2",
"value": "20"
}]
}
and I want:
"Level2": [{
"id": "Chart",
"Box": [{
"id": "1",
"value": "10"
},{
"id": "2",
"value": "20"
}]
}]
Is there any way to get the level 2 ?

Surely you just do
var level1 = _jsonMaster["Level1"];
The problem is that you've gone one level too far.

The object you are interested in "Level2": [...] is not a JArray itself but is a JProperty. You can get it by searching properties of Level1 but keep in mind you will now have a JProperty rather than a JArray. The Value of that result will be the JArray you were getting in your current code.
JProperty contasdasd = _jsonMaster["Level1"].First(o => (o as JProperty).Name == "Level2") as JProperty;
Console.WriteLine(contasdasd.ToString()); // Will be what you are looking for
Console.WriteLine(contasdasd.GetType()); // Will return JProperty
Console.WriteLine(contasdasd.Value.GetType()); // Will return JArray
