BigBytes.JsonParticle 1.0.0

Json Particle

C# Library for extending object capabilities with easy serialization and deserialization using JSON format.

Provides simple object mapper that allows to convert objects between different class types using JSON serialization.

Allows deserialization from TOML format.

Depends on brilliant Newtonsoft.Json package.

Example

Json<T>

Derrive from BigBytes.JsonParticle.Json<T> to add static methods Serialize and Deserialize to the class.

public class Record : BigBytes.JsonParticle.Json<Record>
{
    public class _Book
    {
        public string Title;
        public int Year;
    }

    public class _Author
    {
        public string Name;
    }

    public _Book Book;
    public _Author Author;
}

var record = new Record()
{
    Book = new Record._Book()
    {
        Title = "UML Distilled",
        Year = 2003,
    },
    Author = new Record._Author()
    {
        Name = "Martin Fowler",
    },
};
var json = Record.Serialize(record);
Console.WriteLine(json);

{
  "book": {
    "title": "UML Distilled",
    "year": 2003
  },
  "author": {
    "name": "Martin Fowler"
  }
}

Reverse conversion is also possible.

var json = @"
{
  ""book"": {
    ""title"": ""UML Distilled"",
    ""year"": 2003
  },
  ""author"": {
    ""name"": ""Martin Fowler""
  }
}
";

var record = Record.Deserialize(json);
            
Console.WriteLine(record.Book.Title);
Console.WriteLine(record.Book.Year);
Console.WriteLine(record.Author.Name);

UML Distilled
2003
Martin Fowler

More advanced example with TOML input.

[book]
title = "UML Distilled"
year = 2003

[author]
name = "Martin Fowler"

var toml = @"
[book]
title = ""UML Distilled""
year = 2003

[author]
name = ""Martin Fowler""
";
var json = new Converter.TomlToJson().Convert(toml);
var record = Mock.Record.Deserialize(json);
Debug.WriteLine(record.Book.Title);  // expect "UML Distilled"
Debug.WriteLine(record.Book.Year);   // expect "2003"
Debug.WriteLine(record.Author.Name); // expect "Martin Fowler"

Last but not least example with ungreedy¹ mapping.

public class Person : Json<Person>
{
    public string Name;
    public string City;
    public int Age;
}

public class Customer : Json<Customer>
{
    public string Name;
    public string City;
    public string Office;
}

Person person;
Customer customer;

person = new Person()
{
    Name = "Andy",
    Age = 21,
    City = "Warsaw",
};

customer = new Mapper<Customer>()
    .Map(person);

Console.WriteLine(customer.Name);              // Outputs: "Andy"
Console.WriteLine(customer.City);              // Outputs: "Warsaw"
Console.WriteLine(customer.Office ?? "NULL");  // Outputs: "NULL"

person = new Mapper<Person>()
    .Map(customer);

Console.WriteLine(person.Name);  // Outputs: "Andy"
Console.WriteLine(person.City);  // Outputs: "Warsaw"
Console.WriteLine(person.Age);   // Outputs: "0"

Voilà.

{
  "name": "Andy",
  "city": "Warsaw",
  "age": 21
}

If you get problems with mapping check if both classes contain Serialize and Deserialize methods. That's the minimum requirement for Mapper<> to work. You shouldn't get any problems when classes are using inheritance from Json<>.

Functions

TomlSectionNameToCSharpName

Converts TOML section name to its C# counterpart.

var toml = "list.one.12";
var csharp = BigBytes.JsonParticle.Utility.TomlSectionNameToCSharpName(toml);
System.Diagnostics.Debug.WriteLine(csharp); // expect "ListOne_12"

CSharpNameToJsonName

Converts C# name to its JSON counterpart.

var csharp = "MyObject";
var json = BigBytes.JsonParticle.Utility.CSharpNameToJsonName(csharp);
System.Diagnostics.Debug.WriteLine(json); // expect "myObject"

Project

Main library project directory contains two project files.

BigBytes.JsonParticle.Legacy.csproj

Notes

1) Ungreedy convertion allows to rewrite values only for fields that are present in both objects without throwing an exception
