Disclaimer: I did went through most of the solution provided here but most of them were talking about OOM exception while Deserialization.
I am trying to serialize an object( it's a Tree) into Json using Json.Net. Everything works fine for small objects but i get OOM exception when i try it with large objects. As it works with smaller object of same datatype i am assuming there is no circular reference (I did inspect my data structure for it). Is there a way where i can convert my object into stream ( this is a Windows Store app ) and generate the Json using that 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;
}
}
In order to convert my object into stream, the code i found out was using a BinaryFormatter which is not available in Windows store app dll's.
