Beyond null – using Option

Nullable<T>, which is embedded in C#, is a great tool to work with null values, but there is a better and more straightforward construct for the handling of null values. Option is a type that provides more expressive tools for conveying the presence or absence of a value, serving as a richer alternative to nullable types.

A brief introduction to Option

At its core, the Option type can be thought of as a container that may or may not contain a value. Typically, it’s represented as either Some (which wraps a value) or None (indicating the absence of a value).

Usually, the implementation of Option looks like this:

public struct Option<T>
{
     private readonly bool _isSome;
     private readonly T _value;
     public static Option<T> None => default;
     public static Option<T> Some(T value) => new Option...
