Как сериализовать JsonPrimitive внутри JsonValue

Question

Я хотел бы иметь следующий Test проходя для всех TestCases:

[TestCase("{\"foo\":\"bar\"}")]             // [PASS]
[TestCase("C:\\temp")]                      // [PASS]
[TestCase("Hi \"\"!")]                      // [FAIL]
[TestCase("{\"\":\"\"}")]                   // [FAIL]
[TestCase("It is a nice day {\"\":\"\"}!")] // [FAIL]
public void JsonValueTests_JsonPrimitiveSerialization_ReturnsEqual (string content)
{
        JsonValue json = new JsonObject ();
        json ["Content"] = new JsonPrimitive (content);

        string serializedJson = json.ToString (); 
        System.Diagnostics.Debug.WriteLine (serializedJson);

        JsonValue deserializedJson = JsonValue.Parse (serializedJson);

        string deserializedContent = deserializedJson["Content"];
        Assert.AreEqual (content, deserializedContent);
}

Но я получаю этот результат:

Tests run: 5 Passed: 2 Inconclusive: 0 Failed: 3 Ignored: 0

Допустим, пользователь только что набрал сообщение как It is a nice day {"":""}!, Я хотел бы получить JsonValue со следующей выходной строкой {"Content": "It is a nice day {\"\":\"\"}!"} и сможет разобрать его обратно. Это все.

Что я делаю неправильно?

Я ставлю точку останова сразу после Debug.WriteLine линия, и поэтому я мог получить следующие выходы с консоли и debugger:

• {"Content": "{\" foo \ ": \" bar \ "}"}
• {"Content": "C: \ temp"}
• {"Content": "Hi \" "!"}
• {"Content": "{\" ": \" "}"}

• {"Content": "Это хороший день {\"":\""}!"}

• "{\"Content\": \"{\\\"foo\\\":\\\"bar\\\"}\"}"

• "{\"Content\": \"C:\\\\temp\"}"
• "{\"Content\": \"Hi \\\"\"!\"}"
• "{\"Content\": \"{\\\"\":\\\"\"}\"}"
• "{\"Content\": \"It is a nice day {\\\"\":\\\"\"}!\"}"

Я не знаю, почему второй " не заменяется на \" на тестовых примерах, которые терпят неудачу.

Консольный вывод:

Answer 1

Не уверен, что это является причиной вашей проблемы, но ваш пустой объект JSON: {"":""} недействительно - у вас не может быть пустого ключа. Пустой объект JSON будет {} если это то, что вы собираетесь.
