Multicast Delegate

It is a delegate which holds the reference of more than one method. Multicast delegates must contain only methods that return void. If we want to call multiple methods using a single delegate all the methods should have the same IO Parameters. To test this, add a new class MultiCastDemo.cs under the project and write the following code:

class MultiCastDemo {
	public void Add(int x, int y) {
		Console.WriteLine("Add: " + (x + y));
	}
	public void Sub(int x, int y) {
		Console.WriteLine("Sub: " + (x - y));
	}
	public void Mul(int x, int y) {
		Console.WriteLine("Mul: " + (x * y));
	}
	public void Div(int x, int y) {
		Console.WriteLine("Div: " + (x / y));
	}
	static void Main() {
		MultiCastDemo mc = new MultiCastDemo();
		MathDel md = mc.Add;
		md += mc.Sub;
		md += mc.Mul;
		md += mc.Div;
		md(100, 50);
		Console.WriteLine();
		md(575, 25);
		Console.WriteLine();
		md -= obj.Mul;
		md(678, 28);
		Console.ReadLine();
	}
}
