Implementing IReadOnlyDictionary with Interface Values in C# : A Clear Guide

When working with objects in C# , especially in scenarios involving data deserialization, you might find yourself facing a challenge: how do you expose an interface that contains an IReadOnlyDictionary with interface values, while the implementation relies on a concrete dictionary with actual values? This situation frequently arises when deserializing JSON into concrete types, making it essential to keep the deserialized data safe from modifications by exposing it as read-only.

In this guide, we'll explore a solution to this problem without needing to create an entirely new dictionary for storing the cast values. Let’s dive into the challenge and the solution step-by-step.

The Challenge

You have the following elements at play:

An interface ISomeValue defined for value representation.

A concrete class SomeValue that implements ISomeValue.

An interface IConfiguration that exposes IReadOnlyDictionary<string, ISomeValue> for users of the configuration.

An internal class Configuration implementing this interface, wherein the actual data resides in a Dictionary<string, SomeValue>.

The aim is to expose the values as read-only while maintaining the integrity of the original data structure.

The Data Structure

Here’s the important part of your initial code:

In this structure, you would typically create a new lazy-loaded dictionary that casts SomeValue instances into ISomeValue. However, we want to find a way to avoid this duplicate memory usage and streamline our code.

The Solution

You can create a view over the original dictionary, meaning you don’t duplicate the data but provide access to it in the format you need. The following class, ReadOnlyDictionaryWrapper, is our solution to this problem. This class will act as a wrapper around your original dictionary, exposing methods and properties required for the IReadOnlyDictionary interface.

ReadOnlyDictionaryWrapper Implementation

Here’s how the wrapper class can be structured:

Integrating the Wrapper

In your Configuration constructor, you can instantiate this wrapper around your original _values dictionary. Here is how you can set this up:

Conclusion

By employing the ReadOnlyDictionaryWrapper, you enable the exposure of your concrete dictionary's values as an IReadOnlyDictionary of interface types without duplicating the original dictionary data structure. This solution not only enhances performance by conserving memory but also maintains the integrity of your data throughout its lifetime.

The challenge of implementing an interface with an IReadOnlyDictionary containing interface values while relying on a normal dictionary with concrete types can be elegantly handled with a simple wrapper approach, ensuring clean and efficient code.

By following the above steps, you can resolve similar issues in your applications with ease and precision!
