How to Retrieve Arrays from Your JSON Configuration File in ASP.NET Core

The Problem

You have a JSON file structured like this:

However, when you attempt to retrieve portions of this configuration using an API call, you find that your efforts return empty results. Let's dive deeper into the solution.

The Solution

Step-by-Step Instruction

Modify Your API Call: Update the GetSettings method in your API to properly access the arrays contained in your JSON configuration file.

Here’s the modified code snippet that does the job:

Understanding the Code

Definition of a Dictionary: The method begins by declaring a Dictionary, which will hold the results. Each key in this dictionary corresponds to an array from the JSON file.

GetChildren Method: The use of GetChildren allows for the retrieval of all subsections (like Standards, PaymentModes, etc.) under "Settings."

Looping through Settings: The foreach loop iterates through each of these settings keys, fetching the corresponding array values and adding them to your response dictionary.

Why It Works

The previous approach of trying to fetch directly into a List<string> didn't account for the structure of your JSON. By iterating through each setting and using the correct syntax, you ensure that your application can properly access and return the expected arrays.

Conclusion

Incorporating this solution ensures that you can successfully retrieve arrays from your configuration file in an ASP.NET Core application. By understanding how to navigate the configuration structure and correctly accessing its elements, you can create more robust applications capable of handling diverse configurations.
