Getting JSON data into C# strings

Question

So I'm making an app and I need to extract data from JSON files dynamically.

Here is a snippet of the JSON file:

{
    "004bb5ee-34ba-484a-924b-31412d898e7e": {
        "title": "obj_survivalobject_elevatordoor_left"
    },
    "00284190-1484-4286-a198-b2ddef768c2e": {
        "description": "Adds shock absorption and provides stability. Great for vehicles to prevent them from easily flipping over. This suspension has a lot of bounce, making it ideal for off-road vehicles.",
        "title": "Off-Road Suspension 2"
    },
    "011c1ffd-7146-4e8d-8c18-17247d768ae2": {
        "title": "obj_spaceship_wall04"
    }
}

There is lots more in the file. But I only need to get the title and the parent of that title. Eg:

Tag: "00284190-1484-4286-a198-b2ddef768c2e"
Name: "Off-Road Suspension 2"

I don't want the description and not all have one.

I will also be using JSON files that are selected by the user while the application is running.

Have you ever deserialized json before? Is there any reason why you haven't tried to deserialise this to a `Dictionary` and pick the results from that ? — TheGeneral, Sep 06 '21 at 01:12

try this

var jsonDeserialized = JsonConvert.DeserializeObject<Dictionary<string,Description>>(json); 
var list = jsonDeserialized.Select(kvp => new TagName { Tag = kvp.Key, 
Name=kvp.Value.title} ).ToList();

var output = JsonConvert.SerializeObject(list);

output

[{"Tag":"004bb5ee-34ba-484a-924b-31412d898e7e","Name":"obj_survivalobject_elevatordoor_left"},
{"Tag":"00284190-1484-4286-a198-b2ddef768c2e","Name":"Off-Road Suspension 2"},
{"Tag":"011c1ffd-7146-4e8d-8c18-17247d768ae2","Name":"obj_spaceship_wall04"}]

or this way

foreach (var item in list)
{
     Console.WriteLine ( $"Tag : {item.Tag}, Name: {item.Name}");
        
}

classes

public class Description
{
    public string description { get; set; }
    public string title { get; set; }
}

public class TagName
{
    public string Tag { get; set; }
    public string Name { get; set; }
}

Try deserializing your Json file into a collection (list/dict/etc).

See here for details about Serializing and Deserializing in C#.
