Simple abstraction and decoupling example

1 minute read

Just code.


We have a logger and a log viewer, could be better but I wanted it to be simple.


This is the window that is also the log viewer
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window, ILogViewer
{
public MainWindow()
{
InitializeComponent();
Logger.RegisterViewer(this);
}

public void Log(string message)
{
// do the write logic
}
}

This is the interface of viewers
public interface ILogViewer
{
void Log(string message);
}
This is logger
public static class Logger
{
static List<ILogViewer> viewers = new List<ILogViewer>();

public static void RegisterViewer(ILogViewer viewer)
{
viewers.Add(viewer);
}

public static void Log(string message)
{
foreach (ILogViewer viewer in viewers)
{
viewer.Log(message);
}
}
}
