Have you ever used delegates in your projects or code?

Yes, delegates in C# are often used to implement callbacks, events, and passing methods as parameters.

A delegate is a type that represents a reference to a method with a specific signature. This allows for dynamic method invocation.

Example of using a delegate:

// Delegate declaration
public delegate void Notify(string message);

class Program
{
    static void Main()
    {
        Notify notify = ShowMessage;
        notify("Hello, delegates!");
    }

    static void ShowMessage(string msg)
    {
        Console.WriteLine(msg);
    }
}

In projects, delegates are useful for event-driven models, such as handling user actions, or for passing logic into methods (e.g., filtering collections).
