c# - 如何在 JsonValue 中序列化 JsonPrimitive

Question

我想让下一个测试通过所有测试用例:

[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);
}

但我得到的结果是:

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

假设用户刚刚输入了一条消息，如 It is a nice day {"":""}!。我想获得具有以下输出字符串的 JsonValue {"Content": "It is a nice day {\"\":\"\"}!"} 并能够解析它后退。就是这样。

我做错了什么？

编辑

我在 Debug.WriteLine 行之后放置了一个断点，这样我就可以从控制台和 debugger 获取下一个输出:

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

• {"Content": "今天天气不错{\"":\""}!"}

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

• "{\"Content\":\"C:\\\\temp\"}"
• "{\"Content\":\"嗨\\\"\"!\"}"
• "{\"内容\":\"{\\\"\":\\\"\"}\"}"
• "{\"Content\":\"今天天气不错 {\\\"\":\\\"\"}!\"}"

我不知道为什么失败的测试用例上的第二个 " 没有替换为 \"。

控制台输出:

不确定这是否是您的问题的原因，但您的空 JSON 对象:{"":""} 无效 - 您不能有空键。一个空的 JSON 对象将是 {} 如果这是您想要的。
