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

While implementing Chain of Responsibility pattern, the request from the sender will be sent to a chain of receivers and one of them will handle it.




But in command pattern, the request from the sender will be sent to a particular object only. Every receiver object are internally command objects. Each of these command objects contain Execute method which is called to trigger the receiver to perform an action.

Here is a sample snippet of command object:

class commandClass {
protected receiverClass receiverObj;
public commandClass(receiverClass obj) {
receiverObj = obj;
}
public virtual void Execute() {
receiverObj.performAction();
}
}
