What is the need for Mediator Pattern
in C# (C Sharp)?

This enforces strong coupling between objects. To reduce this coupling and to have a mediator class to mediate between two objects, you implement mediator pattern. Here is a sample code of mediator class:

public class mediatorClass {
private derivedClass1 obj1;
private derivedClass2 obj2;
public derivedClass1 Obj1 {
set { obj1 = value; }
}
public derivedClass2 Obj2 {
set { obj2 = value; }
}
public void sendMessage(string msg, baseClass obj) {
if(obj == obj1) {
obj2.notifyCommunication(msg);
}
else if(obj == obj2) {
obj1.notifyCommunication(msg);
}
}
}

This is just a partial code snippet. Your program should also include an abstract class called baseClass that contains mediatorClass instance as its member. This baseClass is inherited by two classes namely derivedClass1 and derivedClass2. In mediatorClass, you create instances of these two derived classes and achieve communication among them using the sendMessage method. Note that your derived classes should implement the method notifyCommunication.
