How to Properly Deserialize JSON with Property Names "1" and "2" in C#

When working with REST APIs in C# , you may encounter challenges, particularly when the JSON response contains property names that deviate from typical naming conventions. A common frustration is dealing with properties named "1" and "2", which are not valid property names in C# . This begs the question: How can you handle JSON properties that are not compliant with C# naming rules?

Understanding the Problem

Imagine you're calling a REST API, and the response includes something like the following JSON structure:

The Challenge

The JSON includes properties "1" and "2" which cannot be directly mapped to C# class properties because:

C# property names must start with a letter and cannot be purely numeric.

Naming conventions dictate that we avoid using ambiguous names.

The Solution: Using the JsonProperty Attribute

Fortunately, you can resolve this dilemma by leveraging the JsonProperty attribute provided by the Newtonsoft.Json library. This allows you to map JSON properties directly to valid C# properties, circumventing naming convention restrictions.

Step-by-step Implementation

Here’s how you can redefine your classes to correctly deserialize the JSON response:

Key Adjustments Made

Renamed Class: Instead of naming the class 2, I named it Two to conform with C# standards.

Used JsonProperty Attribute: This attribute allows us to specify the exact property name as defined in the JSON.

E.g., One and TwoList are useful names that maintain clarity while mapping to their respective JSON properties.

Conclusion

Handling non-standard property names in JSON can seem daunting, but utilizing the JsonProperty attribute allows seamless integration with C# . By following the steps outlined above, you can easily deserialize JSON data while adhering to C# naming conventions, increasing both the readability and maintainability of your code.

Remember, properly structuring your classes not only aids in deserialization but also enhances the overall quality of your codebase.

With these practices in place, you're now equipped to tackle similar issues with JSON deserialization in C# . Happy coding!
