In this example, we define a Message class that implements the IMessage interface. We then define a SendMessage method that takes a Socket and an IMessage as arguments, serializes the message into a byte array, and sends it over the socket. Package Library: System.Net.Sockets Example 2: Receiving a message using IMessage:C# public static IMessage ReceiveMessage(Socket socket) { byte[] buffer = new byte[1024]; socket.Receive(buffer); IMessage message = DeserializeMessage(buffer); return message; } private static IMessage DeserializeMessage(byte[] buffer) { // Convert byte array to IMessage } ``` In this example, we define a ReceiveMessage method that takes a Socket as an argument, receives a message from the socket and returns it as an IMessage. We also define a DeserializeMessage method that converts the byte array received from the socket into an IMessage object. Package Library: System.Net.Sockets Overall, the IMessage interface is useful for creating a unified messaging system that can be used in a variety of communication scenarios. It enables developers to define a common structure for messages that can be exchanged between different components of a system without worrying about the underlying communication protocol.
