Imagine you are working on a berry farm 🌱, and you need to send a message to another berry picker to let them know how many strawberries you picked. You need a way to pass information from one worker to another.

We need to create a special message card (event data) that includes:

• A message (e.g., "Strawberries picked! 🍓")
• The number of berries picked

We create a special BerryEvent that holds our message:

public class BerryEvent : EventArgs
{
    public string Message { get; }
    public int BerryCount { get; }

    public BerryEvent(string message, int berryCount)
    {
        Message = message;
        BerryCount = berryCount;
    }
}

Now, we have a way to store important berry-related information!

Just like how farmers shout out updates to the team, we need a way to announce when berries have been picked! 🎤

public event EventHandler<BerryEvent> BerryPicked;

Now, whenever berries are picked, we can send this message to other pickers.

When someone picks berries, we send the update:

BerryPicked?.Invoke(this, new BerryEvent("Strawberries picked! 🍓", 42));

This means:
✅ Tell all berry pickers that strawberries were picked.
✅ Send the number of strawberries (42) along with the message.

Now, another berry picker listens for the update and takes action:

private void OnBerryPicked(object sender, BerryEvent e)
{
    Console.WriteLine($"{e.Message} Total berries: {e.BerryCount}");
}

// Subscribe to the berry announcements!
farm.BerryPicked += OnBerryPicked;

Now, whenever berries are picked, all pickers will hear the update! 📢

✅ We created a BerryEvent to hold messages.
✅ We announced when berries were picked.
✅ Other berry pickers received the message and took action!

Just like that, our berry farm runs smoothly with clear communication! 🚜
