Self referencing loop when converting WordDocument object to json.

[Benjamin Deng]

Environment: 

• Newtonsoft.Json 13.0.3,
• Syncfusion.DocIO.AspNet.Mvc5 28.2.6
• dotnet framework 4.2.6.
  
  

Issue: I'm trying to convert a WordDocument object to JSON, following the example provided here. However, I encountered the following error:

Newtonsoft.Json.JsonSerializationException: 'Self referencing loop detected for property 'Document' with type 'Syncfusion.DocIO.DLS.WordDocument'. Path 'Data.Footnotes.Separator.Paragraphs[0].ChildEntities[0].CharacterFormat'.'

Attempts to Resolve:

1. ReferenceLoopHandling.Ignore: This setting caused a memory leak, eventually leading to the program being killed by the OS.
2. ReferenceLoopHandling.Serialize: This setting resulted in a stack overflow.
3. PreserveReferencesHandling.Objects: This setting did not resolve the self-referencing exception.

Could you please help me solve this problem? Any guidance or suggestions would be greatly appreciated. Thank you in advance!

Hi Benjamin,

The problem arises from serializing the DocIO instance. To resolve this issue, please follow these steps:

• Add below Nuget to your project
  

  <PackageReference Include="Syncfusion.EJ2.WordEditor.AspNet.Mvc5" Version="28.2.6" />

• Add the following statement to differentiate the DocIO and EJ2Document instances
  

  using EJ2WordDocument = Syncfusion.EJ2.DocumentEditor.WordDocument;
  using DocIOWordDocument= Syncfusion.DocIO.DLS.WordDocument;
   Copy

  
  
• Pass the stream DocumenEditor Load API and serialize the EJ2Document editor document instance. 
  

  EJ2WordDocument document = EJ2WordDocument.Load(stream, FormatType.Docx);
  string json = Newtonsoft.Json.JsonConvert.SerializeObject(document);
  document.Dispose();
   Copy
