Clean Code with C#
By :

Option types and the Maybe monad are concepts that are used in functional programming to handle the absence of a value or represent a computation that might fail. While C# doesn’t have built-in support for option types and the Maybe monad, we can implement them using custom classes or leverage third-party libraries such as LanguageExt
and CSharpFunctionalExtensions
to achieve similar functionality.
Option types represent the presence or absence of a value, providing a safe alternative to using null references. Instead of directly returning null when a value is not found or when an operation fails, option types allow us to explicitly indicate the absence of a value.
Here’s an example of an option type in C#:
public class Option<T>{ private readonly T value; public bool HasValue { get; } public T Value => HasValue ? value : throw new InvalidOperationException...
