How to Handle Self-Referencing Loops in JSON Serialization with JSON.NET?

JSON serialization of the self -reference cycle in json.net

When using a model generated by serialization from the physical data model (EDM), an error may be encountered: "the self -reference loop of the type system.data.entity is detected." This error is due to the entire attributes of traversing and serialized objects due to the serialization process, including those self -referenced attributes.

The method of solving this problem is to use the JsonConvert.SerializeObject class provided by json.net. This allows you to customize serialization.

The key setting that needs to be configured is , which controls how to process cyclic reference during serialization. By default, it is set to , which causes abnormalities when the cycle reference is detected.

ReferenceEloophandling options: ReferenceLoopHandling ReferenceLoopHandling.Error

ReferenceLoophandling.error: (default) Digital abnormalities when encountering cycle references.

ReferenceLoophandling.Serialize:

By creating a placeholder for the object and replacing it with the previous serialized placement, the serialization cycle reference. Suitable for nested objects with a clear structure.
• ReferenceLoophandling.ignore: If the object is its own sub -object, skip its serialization.
• Example:
• To deal with cycle references, you can set to :

PreserveObjectReferences

If the stack overflow occurs during the serialization due to unlimited nested objects,

attributes can be used to avoid this problem. ReferenceLoopHandling ReferenceLoopHandling.Serialize Example:

<code class="language-csharp">JsonConvert.SerializeObject(YourPOCOHere, Formatting.Indented,
new JsonSerializerSettings
{
    ReferenceLoopHandling = ReferenceLoopHandling.Serialize
});</code>

Select the appropriate and

settings according to the structure of the object, you can successfully process the self -reference loop using json.net for the JSON serialization period.
