Serializing an object using Json.Net raises a memory exception

Question

Disclaimer: I have done most of the solution proposed here, but most of them talked about OOM exception, and Deserialization.

I am trying to serialize an object (this tree) in Json using Json.Net. Everything works fine for small objects, but I get an OOM exception when I try to use it with large objects. Since it works with a smaller object of the same data type, I assume that there is no circular reference (I checked my data structure for it). Is there a way to convert my object to a stream (this is a Windows Store app) and generate Json using this stream?

 public static async Task<bool> SerializeIntoJson<T>(string fileName, StorageFolder destinationFolder, Content content)
    {
        ITraceWriter traceWriter = new MemoryTraceWriter();
        try
        {

            string jsonString = JsonConvert.SerializeObject(content, Formatting.Indented, new JsonSerializerSettings
            {
                PreserveReferencesHandling = PreserveReferencesHandling.Objects,
                TypeNameHandling = TypeNameHandling.All,
                Error = ReportJsonErrors,
                TraceWriter = traceWriter,
                StringEscapeHandling = StringEscapeHandling.EscapeNonAscii
            });
            System.Diagnostics.Debug.WriteLine(traceWriter);

            StorageFile file = await destinationFolder.CreateFileAsync(fileName, CreationCollisionOption.ReplaceExisting);
            await Windows.Storage.FileIO.WriteTextAsync(file, jsonString);
            return true;
        }
        catch (NullReferenceException nullException)
        {
            System.Diagnostics.Debug.WriteLine(traceWriter);
            logger.LogError("Exception happened while serializing input object, Error: " + nullException.Message);
            return false;
        }
        catch (Exception e)
        {
            System.Diagnostics.Debug.WriteLine(traceWriter);
            logger.LogError("Exception happened while serializing input object, Error: " + e.Message, e.ToString());
            return false;
        }
    }

Answer 1

, , . , , StreamWriter (JsonWriter TextWriter).

TextWrite

using (TextWriter textWriter = File.CreateText("LocalJsonFile.json"))
{
    var serializer = new JsonSerializer();
    serializer.Serialize(textWriter , yourObject);
}

, StringWriter

  StringBuilder sb = new StringBuilder();
  StringWriter sw = new StringWriter(sb);

  using(JsonWriter textWriter = new JsonTextWriter(sw))
  {
     var serializer = new JsonSerializer();
     serializer.Serialize(textWriter, yourObject);
  }

public static async Task<bool> SerializeIntoJson<T>(string fileName, StorageFolder destinationFolder, Content content)
    {
        try
        {
            StorageFile file = await destinationFolder.CreateFileAsync(fileName, CreationCollisionOption.ReplaceExisting);
            using (var stream = await file.OpenStreamForWriteAsync())
            {

                StreamWriter writer = new StreamWriter(stream);
                JsonTextWriter jsonWriter = new JsonTextWriter(writer);
                JsonSerializer ser = new JsonSerializer();

                ser.Formatting = Newtonsoft.Json.Formatting.Indented;
                ser.PreserveReferencesHandling = PreserveReferencesHandling.Objects;
                ser.TypeNameHandling = TypeNameHandling.All;
                ser.Error += ReportJsonErrors;

                ser.Serialize(jsonWriter, content);

                jsonWriter.Flush();

            }
            return true;
        }
        catch (NullReferenceException nullException)
        {

            logger.LogError("Exception happened while serializing input object, Error: " + nullException.Message);
            return false;
        }
        catch (Exception e)
        {

            logger.LogError("Exception happened while serializing input object, Error: " + e.Message, e.ToString());
            return false;
