Mastering JSON Deserialization in C# and .NET 6

As developers, we often encounter JSON data that needs to be deserialized into our programs. However, there are times when the JSON structures we face are more complex, and getting them into manageable objects can prove to be a challenge. This post aims to tackle those scenarios specifically in C# and .NET 6, using JsonSerializer.Deserialize() from the System.Text.Json namespace.

The Problem at Hand

In the case at hand, we need to deserialize a JSON array with multiple objects that cannot be lumped together without causing issues.

Here’s a look at the given JSON Example:

In this example, if you try to deserialize using a generic list, you end up with two different objects being merged into one model, leading to incomplete data for each instance. This problem arises because the generated classes from visual tools do not adequately separate the distinct types of objects in your JSON.

The generated classes might look like this:

The Core Challenge

The generated Class1 combines properties from both objects into a single class, which is not what we need. We need distinct classes that accurately represent our JSON structure.

A Solution for Clearer Deserialization

To regain control over our JSON deserialization, we should modify the original JSON format and the corresponding class definitions. The ideal structure would look something like this:

Revised C# Classes

With this new JSON structure, we can define two separate classes for clearer representation and easier deserialization:

Deserialization Code Example

With the appropriate JSON structure and classes set up, deserialization becomes straightforward. Below is how you would handle the deserialization in C# :

Conclusion

By rewriting the JSON input and establishing clear class definitions, you can successfully deserialize complex JSON objects into their respective types without the confusion of merging differing properties. This solution allows you to maintain the integrity of your data and ensures that when you perform serialization later, your modified classes retain the necessary format.

Employ these strategies to manage your JSON data more effectively, and see how they can greatly enhance your efficiency when working with .NET applications.
