Very good video!

Boom, job done. Also, I don't think the comment about case sensitivity with properties is accurate, as I always go back through and change my properties to uppercase to keep them standardized.
Hey Two TinyTrees, Thanks for leaving a great message that I'm sure will help others. You are 100% correct about CASE SENSITIVITY, by default Newtonsoft is case insensitive.

Do you think you could have added one class called "country" instead of "worldInvestor" and in this case "_accounts" will only have one property under it called "List countries"
Hey Essam, this is a good question. so, "USA","SLOVAKIA", "ECUADOR",""MEXICO" are objects. that is why I had to create "worldInvestor", for each "instance" of "worldInvestor", I had to "NAME" "usa","slovakia","ecuador","mexico", so NewtonSoft could MAP those object correctly. this doesn't mean, the way I think is correct, It's just a pattern I use to solve these type of JSON problems. I try to keep it as simple as POSSIBLE every single time.

Ex3: Step-by-Step, I will show you the steps it takes to build C# class objects to DESERIALIZE JSON. ruclips.net/video/Qp4f6ZJKciE/видео.html 1) Build class object C# 2) Serialize (c# -> JSON) 3) So, try out the worldInvestor problem with your class object design, then serialize 4) Let me know your results. 5) hope this helps
In example 4; What if there was more than 4 countries? For example there is 1500 countries, we should add one by one like this? How we can generate it automatically?
Hey Arin, plz don't do one-by-one. First question, is the JSON valid? Second Question: do you understand key, value. in example #4, the countries (are the key, and the value are big objects), so, this is not the format you want. Are you the person that designed the JSON? Can you send me the JSON? softwareNugget65@gmail.com Do you have visual studios?

I’m writing a program where a new object is created and added to a list every time I click, then saved when another button is clicked. If I create a list of those objects can I then do a similar thing here and mash them all into one big json file? To be more specific, it’s a school project where I’m making a golf app. Every time I click I need to store information about each shot (the surface type, the coordinates etc). But when I want to save it I want there to be “hole” : 1 followed by the list of shots as objects, then “strokes” : 5 for example. Is that possible?

@@SoftwareNuggets Somehow I didn't get a notification of YT of your answer, I'm just reading this. Thanks, very much appreciated, I'm going to check this out to see if I can wrap my head around this :)
Do you think you could have added one class called "country" instead of "worldInvestor" and in this case "_accounts" will only have one property under it called "List countries"
Hey Essam, this is a good question.
so,
"USA","SLOVAKIA", "ECUADOR",""MEXICO" are objects.
that is why I had to create "worldInvestor",
for each "instance" of "worldInvestor", I had to "NAME" "usa","slovakia","ecuador","mexico", so NewtonSoft could MAP those object correctly.
this doesn't mean, the way I think is correct, It's just a pattern I use to solve these type of JSON problems. I try to keep it as simple as POSSIBLE every single time.
Hey Essam, I just put out another video about JSON Deserialization. I think if you watch this video, it will give you some ideas.
Ex3: Step-by-Step, I will show you the steps it takes to build C# class objects to DESERIALIZE JSON.
ruclips.net/video/Qp4f6ZJKciE/видео.html
1) Build class object C#
2) Serialize (c# -> JSON)
3) So, try out the worldInvestor problem with your class object design, then serialize
4) Let me know your results.
5) hope this helps
However, when you come to get 3rd party API, it is a different story. I have difficult to show the response as c# classes.
Can you send the json to softwarenugget65@gmail.com, and I will take a look
In example 4; What if there was more than 4 countries? For example there is 1500 countries, we should add one by one like this? How we can generate it automatically?
Hey Arin, plz don't do one-by-one. First question, is the JSON valid? Second Question: do you understand key, value. in example #4, the countries (are the key, and the value are big objects), so, this is not the format you want.
Are you the person that designed the JSON?
Can you send me the JSON?

Do you have visual studios?
Please watch this video, it may help you:

I created this video in Jan 2022.
I’m writing a program where a new object is created and added to a list every time I click, then saved when another button is clicked. If I create a list of those objects can I then do a similar thing here and mash them all into one big json file?
To be more specific, it’s a school project where I’m making a golf app. Every time I click I need to store information about each shot (the surface type, the coordinates etc). But when I want to save it I want there to be “hole” : 1 followed by the list of shots as objects, then “strokes” : 5 for example. Is that possible?
Serialize object and your done.
@@SoftwareNuggets I’ll see what I can do, I’m still fairly new to c#
Another question if you don’t mind, what does Get set and that notation it’s surrounded in do?
Those allow you to give and get a value from that field. Say you wanted a read only field, you would only apply the get
www.w3schools.com/cs/cs_properties.php
Did that link about Get and Set make sense?
And why doesn't it support BSON out of the box?
Newtonsoft json must be installed. That’s what I meant. Sorry for the confusion.
But how can I deserialize json that looks like this [ {} ]
static void Main(string[] args)
{
string filename = @"c:\temp\youtube\customer.json";
// let's build a C# class object
var dyn_obj = BuildDynamicObj();
// let's convert c# class object to a "json" object
var json = Newtonsoft.Json.JsonConvert.SerializeObject(dyn_obj);
if (System.IO.File.Exists(filename) == false)
{
System.IO.File.WriteAllText(filename, json);
}
else
{
System.IO.File.Delete(filename);
System.IO.File.WriteAllText(filename, json);
}
var data = JsonConvert.DeserializeObject(json);
}
private static List BuildDynamicObj()
{
var a = new List
{
new { }
};
return (a);
}

How to generate XML from this file and save it in the folder?
Hey @robsoncardoso8692, so you have a file that is formatted in json, and you want to convert it to xml?
I found this on the internet, it untested :
string json = @"{
'@Id': 1,
'Email': 'james@example.com',
'Active': true,
'CreatedDate': '2013-01-20T00:00:00Z',
'Roles': [
'User',
'Admin'
],
'Team': {
'@Id': 2,
'Name': 'Software Developers',
'Description': 'Creators of fine software products and services.'
}
}";
XNode node = JsonConvert.DeserializeXNode(json, "Root");
Console.WriteLine(node.ToString());
@@SoftwareNuggets yes, i have this file:
{
"ide": {
"nf": {
"cUF": 42,
"cNF": 43617
}
}
}
Did you try the command I provided in my previous comment?
