Concrete Handlers:?

• The InfoLogger and ErrorLogger are concrete handlers that implement

the Logger class. Each handler checks if it can handle a particular log level

Follow:

(e.g., Info or Error). If it can, it processes the log; otherwise, it passes it along

to the next handler in the chain.

public class InfoLogger : Logger

protected override bool CanHandle(LogLevel level) => level ==

LogLevel.Info;

protected override void Handle(string message) =>

Console.WriteLine($"Info: {message}");

public class ErrorLogger : Logger

protected override bool CanHandle(LogLevel level) => level ==

LogLevel.Error;

protected override void Handle(string message) =>

Console.WriteLine($"Error: {message}");
