❔ ✅ JSON Serialization not working?

Can someone help me with this one, in the MS docs this seems to work just fine, what am i doing wrong..

using System;
using System.Collections.Generic;
using System.Text.Json;

namespace JSONSerialization
{
    class Program
    {
        static void Main(string[] args)
        {    
            Infos infos = new Infos("TestName", 9283943);

            var options = new JsonSerializerOptions { WriteIndented = true };
            string serializedContent = JsonSerializer.Serialize(infos, options);
            Console.WriteLine(serializedContent);
        }
    }
    class Infos
    {
        public string name = "";
        public int id = 0;


        public Infos(string name, int id)
        {
            this.name = name;
            this.id = id;
        }
    }
}

using System;
using System.Collections.Generic;
using System.Text.Json;

namespace JSONSerialization
{
    class Program
    {
        static void Main(string[] args)
        {    
            Infos infos = new Infos("TestName", 9283943);

            var options = new JsonSerializerOptions { WriteIndented = true };
            string serializedContent = JsonSerializer.Serialize(infos, options);
            Console.WriteLine(serializedContent);
        }
    }
    class Infos
    {
        public string name = "";
        public int id = 0;


        public Infos(string name, int id)
        {
            this.name = name;
            this.id = id;
        }
    }
}

What do you see which makes you think that isn't working?

canton7•2y ago

Ah, you're using fields rather than properties

KenseiOP•2y ago

is that the issue?

Yes

KenseiOP•2y ago

in that case, thanks a lot !

Most serializers will ignore fields, and just process properties. You should never have a public field, really

KenseiOP•2y ago

yeah it wasn't public at first, it thought it had something to do with it, so i tried everything

canton7•2y ago

Yeah, it also needs to be public

KenseiOP•2y ago

the one from newtonsoft seems to work fine so that's why i was confused

canton7•2y ago

Yeah, different defaults.

canton7•2y ago

Looks like you can configure S.T.J to use fields: https://stackoverflow.com/a/58139922/1086121

How to use class fields with System.Text.Json.JsonSerializer?

I recently upgraded a solution to be all .NET Core 3 and I have a class that requires the class variables to be fields. This is a problem since the new System.Text.Json.JsonSerializer doesn't support

KenseiOP•2y ago

oh neat thanks!

canton7•2y ago

Looks like you can use [JsonInclude] to use properties with private setters, but doesn't seem to work on private properties But, you should normally just use public properties in classes intended for serialization

KenseiOP•2y ago

yeah, i'm quite satisfied with this result, at first i thought the dictionary i had included was being faulty, cus i heard some serializers don't like dictionaries much but this one works nicely, + it's simple and can just be serialized directly to a string, exactly what i need

Sweet!
