How Can JSON.Net Handle Inconsistent Property Types in JSON Data?

Use json.net to process the inconsistent attribute type in JSON data

When processing JSON data, it often encounters inconsistent attribute formats, which will bring challenges to serialization and derivativeization. A common problem is that attributes can be a single item or array. For example, the "Category" attribute of Sendgrid API can be a string or a string array.

In order to manage this inconsistency with JSON.NET, custom JSONCONVERTER provides an effective solution. The following is its working principle:

Model definition:

1. Define a model class, the attribute name is "categories", the statement is listed , and the [JSONCONVER] attribute specifies the custom converter type.

   Custom converter implementation:

2. Create a generic SingleorrayConverter

   class inherited from JSONCONVERRER. Implement the ReadJSON method to process the logic logic:

   Check the type of JSON mark: If it is an array, it will be serialized into a list; if it is NULL, return NULL; otherwise, the valuable value of the dependentization is wrapped in the list.
   • Usage:
Specify this custom converter in the "Categories" property of the model class. Then, using JSONCONVERT to sequence JSON data into a list of model objects.

3. serialization (optional):

   In order to process serialization in a consistent way, the Writejson method is implemented in a custom converter. If the list contains a single item, the serial sequence is turned into a single value; otherwise, the list is serialized into an array.

4. This method allows you to seamlessly handle inconsistent attribute types during the periodicization and serialization, and ensure that your application can effectively process JSON data with specific properties with different formats.
