使用 Newtonsoft 序列化 Json 个对象的列表会导致许多“\r\n”格式不正确

Question

下面是我的代码片段：

private void Save(object sender, EventArgs e)
        {
            var readText = File.ReadAllText(FilePath);

            JObject jsonObject = JsonConvert.DeserializeObject(readText) as JObject;
            string cfgStr = JsonConvert.SerializeObject(ListViewContents, Formatting.Indented);
            jsonObject["JoystickName"]["input_bindings"] = cfgStr;

            File.WriteAllText(FilePath, jsonObject.ToString());
            Navigation.PushAsync(new MainPage());
        }

我正在尝试序列化 json 个对象的列表，ListViewContents 是一个对象列表，因为每个输入绑定都可以不同。当我序列化列表并写入文件时，它会将所有输入绑定写入一行，并将其作为输出：

"input_bindings": "[\r\n  {\r\n    \"topic\": \"hwi.te0_ptt_wog.cableCutCover\",\r\n    \"input_type\": \"button\",\r\n    \"output_type\": \"boolean\",\r\n    \"button_id\": \"DPad Down\",\r\n    \"invert\": true\r\n  },\r\n  {\r\n    \"topic\": \"hwi.te0_ptt_wog.cableCut\",\r\n    \"input_type\": \"button\",\r\n    \"output_type\": \"boolean\",\r\n    \"button_id\": \"DPad Left\"\r\n  },\r\n  {\r\n    \"topic\": \"hwi.te0_ptt_wog.winchArmSwitch\",\r\n    \"input_type\": \"button\",\r\n    \"output_type\": \"boolean\",\r\n    \"button_id\": \"DPad Right\"\r\n  },\r\n  {\r\n    \"topic\": \"hwi.te0_ptt_wog.bottomRight\",\r\n    \"input_type\": \"button\",\r\n    \"output_type\": \"boolean\",\r\n    \"button_id\": \"L3\"\r\n  },\r\n  {\r\n    \"topic\": \"hwi.te0_ptt_wog.topLeft\",\r\n    \"input_type\": \"button\",\r\n    \"output_type\": \"boolean\",\r\n    \"button_id\": \"Select\"\r\n  },\r\n  {\r\n    \"topic\": \"hwi.te0_ptt_wog.mic_en\",\r\n    \"input_type\": \"button\",\r\n    \"output_type\": \"boolean\",\r\n    \"button_id\": \"Start\"\r\n  },\r\n  {\r\n    \"topic\": \"hwi.te0_ptt_wog.hot_mic_en\",\r\n    \"input_type\": \"button\",\r\n    \"output_type\": \"boolean\",\r\n    \"button_id\": \"R3\"\r\n  },\r\n  {\r\n    \"topic\": \"hwi.te0_ptt_wog.wog_present\",\r\n    \"input_type\": \"button\",\r\n    \"output_type\": \"boolean\",\r\n    \"button_id\": \"DPad Up\"\r\n  },\r\n  {\r\n    \"topic\": \"hwi.te0_ptt_wog.winchCommand\",\r\n    \"input_type\": \"axis\",\r\n    \"output_type\": \"analog\",\r\n    \"axis_id\": \"Trigger Left\",\r\n    \"scalar\": -1.0,\r\n    \"bias\": 0.0\r\n  }\r\n]"

理想情况下，整个 JSON 文件如下所示：

{
  "g" : "${import:../global.json}",
  "JoystickName": {
     "output_uri" : "placeholder",
     "ctrl_uri"   : "placeholder",
     "log": {
        "level": 2,
        "uri": "placeholder"
      },
    "device": "placeholder",
    "input_bindings": [
      {
        "topic": "hwi.te0_ptt_wog.cableCutCover",
        "input_type": "button",
        "output_type": "boolean",
        "button_id": "DPad Down",
        "invert" :  true
      },
      {
        "topic": "hwi.te0_ptt_wog.cableCut",
        "input_type": "button",
        "output_type": "boolean",
        "button_id": "DPad Left"
      },
      {
        "topic": "hwi.te0_ptt_wog.winchArmSwitch",
        "input_type": "button",
        "output_type": "boolean",
        "button_id": "DPad Right"
      },
      {
        "topic": "hwi.te0_ptt_wog.bottomRight",
        "input_type": "button",
        "output_type": "boolean",
        "button_id": "L3"
      },
      {
        "topic": "hwi.te0_ptt_wog.topLeft",
        "input_type": "button",
        "output_type": "boolean",
        "button_id": "Select"
      },
      {
        "topic": "hwi.te0_ptt_wog.mic_en",
        "input_type": "button",
        "output_type": "boolean",
        "button_id": "Start"
      },
      {
        "topic": "hwi.te0_ptt_wog.hot_mic_en",
        "input_type": "button",
        "output_type": "boolean",
        "button_id": "R3"
      },
      {
        "topic": "hwi.te0_ptt_wog.wog_present",
        "input_type": "button",
        "output_type": "boolean",
        "button_id": "DPad Up"
      },
      {
        "topic": "hwi.te0_ptt_wog.winchCommand",
        "input_type": "axis",
        "output_type": "analog",
        "axis_id": "Trigger Left",
        "scalar": -1.0,
        "bias": 0.0
      }
    ]
  }
}

一旦我将“input_bindings”分配给 cfgStr，就会出现这种奇怪的格式。

任何帮助将不胜感激，我在搜索时找不到与我的问题相似的帖子。

这是问题所在：

string cfgStr = JsonConvert.SerializeObject(ListViewContents, Formatting.Indented);
jsonObject[JoystickName]["input_bindings"] = cfgStr;

您将 input_bindings 的值设置为“序列化 JSON 的结果”（即字符串）。然后，您将序列化整个对象（使用 jsonObject.ToString()），以便序列化该字符串，包括转义所有内容。您只想序列化一次.

我怀疑你只是想要：

jsonObject[JoystickName]["input_bindings"] = JArray.FromObject(ListViewContents);

换句话说，将 ListViewContents 转换为 LINQ to JSON 模型，但 还没有 将其序列化为字符串。
