Multicast Delegates:

• Delegates can combine multiple methods into a single delegate instance.
• Multicast delegates allow you to call multiple methods with a single delegate invocation.
• The += and -= operators are used to add and remove methods from a multicast delegate.

Example:

public delegate void MyDelegate();

public class MyClass

{

    public void Method1()

    {

        Console.WriteLine(“Method 1”);

    }

    public void Method2()

    {

        Console.WriteLine(“Method 2”);

    }

}

// Usage:

MyClass obj = new MyClass();

MyDelegate delegateObj = obj.Method1;

delegateObj += obj.Method2;

delegateObj();

// Output:

// Method 1

// Method 2

Delegates and events are powerful mechanisms for implementing event-driven programming in C#. They allow loose coupling between components, enabling better code organization and separation of concerns. By using delegates and events, you can build flexible and extensible systems that respond to events and enable communication between different parts of your program.
