Below is a snippet of my code:
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());
}
I am trying to serialize a list of json objects, ListViewContents is a list of objects as each input binding can be different. When I serialize the list and write to the file, it writes all of the input bindings on one line with this as an output:
"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]"
Ideally, the entire JSON file looks like this:
{
"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
}
]
}
}
Once I assign "input_bindings" to cfgStr, this strange formatting occurs.
Any help would be greatly appreciated, and I was unable to find any posts similar to my problem while searching.
This is the problem:
string cfgStr = JsonConvert.SerializeObject(ListViewContents, Formatting.Indented);
jsonObject[JoystickName]["input_bindings"] = cfgStr;
You're setting the value of input_bindings to "the result of serializing JSON" (i.e. a string). You're then serializing the whole object (with jsonObject.ToString()), so that serializes that string, including escaping everything. You only want to serialize once.
I suspect you just want:
jsonObject[JoystickName]["input_bindings"] = JArray.FromObject(ListViewContents);
In other words, convert ListViewContents into the LINQ to JSON model, but don't serialize it as a string yet.
