Overview

qpJsonParser is a JSON parser licensed under NYSL Version 0.9982, wrriten in C#.

Example

Example 1

Code

using qpwakaba;
/*
    {
      "number": 334,
      "string": "foo",
      "boolean": true,
      "null": null,
      "array": [1.0, 0.2, -3E+4, -5E-6, "33-4"],
      "object": {
        "name": "qpJsonParser",
        "version": "1.0.0.0"
      }
    }
*/

string json = "{\"number\":334,\"string\":\"foo\",\"boolean\":true,\"null\":null,\"array\":[1.0,0.2,-3E+4,-5E-6,\"33-4\"],\"object\":{\"name\":\"qpJsonParser\",\"version\":\"1.0.0.0\"}}";

IJsonValue deserialized = JsonParser.Parse(json);
// Write "JsonParser.Parse(json, true)" to keep key order

foreach(var value in (JsonObject)deserialized)
{
  Console.WriteLine(value.ToString());
}

Output

[number, 334]
[string, foo]
[boolean, true]
[null, null]
[array, [1.0, 0.2, -3E+4, -5E-6, "33-4"]]
[object, {"name": "qpJsonParser", "version": "1.0.0.0"}]

Example 2

Code

using qpwakaba;
/*
    {
      "number": 334,
      "string": "foo",
      "boolean": true,
      "null": null,

      "object": {
        "name": "qpJsonParser",
        "version": "1.0.0.0"
      }
    }
*/

string json = "{\"number\":334,\"string\":\"foo\",\"boolean\":true,\"null\":null,\"array\":[1.0,0.2,-3E+4,-5E-6,\"33-4\"],\"object\":{\"name\":\"qpJsonParser\",\"version\":\"1.0.0.0\"}}";

JsonObject deserialized = (JsonObject)JsonParser.Parse(json);

//IJsonObject.Cast<T> is a extension method.
var number = deserialized["number"].Cast<JsonNumber>();

double doubleValue = number.DoubleValue; // 334.0
int intValue = number.IntegerValue; // 334

var _string = deserialized["string"]; // "foo" (JsonString)

var boolean = deserialized["boolean"]; // true (JsonBoolean)

var _null = deserialized["null"]; // null (JsonNull)

var array = deserialized["array"]; // (JsonArray)
// ((JsonArray) array)[0] == 1.0 (JsonNumber)
// ((JsonArray) array)[1] == 0.2 (JsonNumber)
// ((JsonArray) array)[2] == -3E+4 (JsonNumber)
// ((JsonArray) array)[3] == -5E-6 (JsonNumber)
// ((JsonArray) array)[4] == "33-4" (JsonString)

var _object = deserialized["object"]; // (JsonObject)

Example 3

Code

using qpwakaba;
/*
    {
      "number": 334,
      "string": "foo",
      "boolean": true,
      "null": null,
      "array": [1.0, 0.2, -3E+4, -5E-6, "33-4"],
      "object": {
        "name": "qpJsonParser",
        "version": "1.0.0.0"
      }
    }
*/

string json = "{\"number\":334,\"string\":\"foo\",\"boolean\":true,\"null\":null,\"array\":[1.0,0.2,-3E+4,-5E-6,\"33-4\"],\"object\":{\"name\":\"qpJsonParser\",\"version\":\"1.0.0.0\"}}";

JsonObject deserialized = JsonParser.Parse(json).Cast<JsonObject>();

string serialized = deserialized.ToJsonCompatibleString();
// Write "ToJsonCompatibleString(true)" to escape unicode characters.

Console.WriteLine(serialized);

Output

{"number": 334, "string": "foo", "boolean": true, "null": null, "array": [1.0, 0.2, -3E+4, -5E-6, "33-4"], "object": {"name": "qpJsonParser", "version": "1.0.0.0"}}
