am generating a json file using c#. One of the properties is a text: " paragraph text 1

". When I save the json file, the text is converted into this: "\u003cp\u003eparagraph text 1\u003c/p\u003e". I would like to preserve the original text. I have an entity named Field. It looks like this:

public partial class Field
    {
        [JsonProperty("name")]
        public string name { get; set; }

        [JsonProperty("identifier")]
        public string identifier { get; set; }

        [JsonProperty("type")]
        public string type { get; set; }

        [JsonProperty("isEditorDialogOpen", NullValueHandling = NullValueHandling.Ignore)]
        public bool? isEditorDialogOpen { get; set; }

        [JsonProperty("paragraphHeight", NullValueHandling = NullValueHandling.Ignore)]
        public string paragraphHeight { get; set; }

        [JsonProperty("integrationID")]
        public string integrationID { get; set; }

        [JsonProperty("hint")]
        public string hint { get; set; }

        [JsonProperty("tooltip")]
        public string tooltip { get; set; }

        [JsonProperty("validations")]
        public object[] validations { get; set; }

        [JsonProperty("permission")]
        public string permission { get; set; }

        [JsonProperty("maskingViewer")]
        public string maskingViewer { get; set; }

        [JsonProperty("defaultValue")]
        public object[] defaultValue { get; set; }

        [JsonProperty("width")]
        public string width { get; set; }

        [JsonProperty("editedParagraph", NullValueHandling = NullValueHandling.Ignore)]
        public string editedParagraph { get; set; }

        [JsonProperty("label")]
        public string label { get; set; }

        [JsonProperty("stepIdx")]
        public long stepIdx { get; set; }

        [JsonProperty("blockIdx")]
        public long blockIdx { get; set; }

        [JsonProperty("rowIdx")]
        public long rowIdx { get; set; }

        [JsonProperty("readOnly", NullValueHandling = NullValueHandling.Ignore)]
        public bool? readOnly { get; set; }

        [JsonProperty("clearable", NullValueHandling = NullValueHandling.Ignore)]
        public bool? clearable { get; set; }

        [JsonProperty("required", NullValueHandling = NullValueHandling.Ignore)]
        public bool? fieldRequired { get; set; }

        [JsonProperty("maxLength", NullValueHandling = NullValueHandling.Ignore)]
        [JsonConverter(typeof(ParseStringConverter))]
        public string maxLength { get; set; }

        [JsonProperty("fieldIdx", NullValueHandling = NullValueHandling.Ignore)]
        public long? fieldIdx { get; set; }

        [JsonProperty("shownInPdfMode", NullValueHandling = NullValueHandling.Ignore)]
        public bool? shownInPdfMode { get; set; }
    }

And this is the json:

"fields": [{
    "name": "editor.fields.paragraph",
    "identifier": "paragraph_kdg3wty6",
    "type": "paragraph",
    "isEditorDialogOpen": false,
    "paragraphHeight": "auto",
    "integrationID": "yobi1_a",
    "hint": "",
    "tooltip": "",
    "validations": [],
    "permission": "both",
    "maskingViewer": "none",
    "defaultValue": [],
    "width": "full",
    "editedParagraph": "\u003cp\u003eparagraph text 1\u003c/p\u003e",
    "label": "",
    "stepIdx": 0,
    "blockIdx": 0,
    "rowIdx": 1,
    "readOnly": null,
    "clearable": null,
    "fieldRequired": null,
    "maxLength": null,
    "fieldIdx": null,
    "shownInPdfMode": null
}]

And this is how I save the file:

var json = new JavaScriptSerializer().Serialize(field);
                //File.WriteAllText(destination, json);
                using (StreamWriter sw = new StreamWriter(File.Open(destination, FileMode.Create), Encoding.Unicode))
                {
                    sw.WriteLine(json);
                }

I tried saving the file as text under any encoding format with no success.

When I try it:

string s = "\u003cp\u003eparagraph text 1\u003c/p\u003e";
string x = "<p>paragraph text 1</p>";
string json1 = JsonConvert.SerializeObject(s);
string json2 = JsonConvert.SerializeObject(x);

I get perfectly respectable json from both strings:

"<p>paragraph text 1</p>"

Even if I assume that your string is a literal:

C#

string s = @"\u003cp\u003eparagraph text 1\u003c/p\u003e";
string json1 = JsonConvert.SerializeObject(s);

Then I still get exactly what I expect
as JSON:

"\\u003cp\\u003eparagraph text 1\\u003c/p\\u003e"

Since '\' is a JSON special character and needs to be escaped.

So ... I'd look closely at the code that generates your JSON and the data it is working from - I'd suspect that your "editedParagraph" string is originating with some form of HTML encoding applied, so that's why you get unicode characters in your output.

Use the debugger and have a close look at what is going on.

OriginalGriff,
Thank you very much for drawing my attention to the problem. I seem to have been chasing my own tail all this time.
Instead of using

JavaScriptSerializer

, I did this and now it works ok:

var json = Newtonsoft.Json.JsonConvert.SerializeObject(main);
File.WriteAllText(destination, json);

One important thing:
I have an override method for

WriteJson

(inherit

JsonConverter

class)
and i hade to modify it:

public override void WriteJson(JsonWriter writer, object untypedValue, JsonSerializer serializer)
        {
            var value = (DefaultValue)untypedValue;
            if (value.Bool != null)
            {
                serializer.Serialize(writer, value.Bool.Value);
                return;
            }
            if (value.String != null)
            {
                serializer.Serialize(writer, value.String);
                return;
            }
            throw new Exception("Cannot marshal type DefaultValue");
        }
