JsonParserNetCore

A C# JSON parser made in .Net Core

Usage

Below is the JSON we'll be using for the examples.

{
	"firstName": "name1",
	"lastName": "name2",
	"age": 22,
	"Address": "address",
	"City": "city",
	"married": false,
	"home number": -1,
	"degrees": ["Computer Science"],
	"department": "IT",
	"phoneNumber": -1,
	"Skills": ["C#", "C++", "Java", "JavaScript", "SQL", "Git", "VideoEditing"],
	"projects": [{
			"name": "DBCLI",
			"description": "A database manager"
		},
		{
			"name": "Automata Visualizer",
			"description": -1,
			"another object": {
				"negative": -25.3
			}
		}
	],
	"permanent": true
}

In order to get the object representation of this JSON, just instantiate the Parser class, with the JSON as argument, and call the Parse method.

var parser = new Parser(json);
var value = parser.Parse();

Use square brackets notation along with the json key in order to access its corresponding value.

value["City"]
//city

value["projects"][1]["another object"]["negative"]
//-25.3

In order to iterate over all the members of the current object, make sure to call the GetKeys method which will return all the keys of the json object.

foreach (var key in value.GetKeys())
{
    Console.WriteLine(value[key]);
}

/*
  name1
  name2
  22
  address
  city
  False
  -1
  IT
  -1
  True
*/

To iterate over the array elements, you are presented with two choices:

1. Use a classic for loop.

for (var i = 0; i < value["projects"].Count; i++)
{
    Console.WriteLine(value["projects"][i]["description"]);
}
/*
  A database manager
  -1
*/

2. Use a foreach loop. In this case, you will need to call the GetValue method for each element to actually get the element stored in the array.

foreach (var skill in value["Skills"])
{
    Console.WriteLine(skill.GetValue());
}

/*
  C#
  C++
  Java
  JavaScript
  SQL
  Git
  VideoEditing
*/

That's all. All the examples above are included in the Program.cs so you can test them by yourself.
