Strategy Design Pattern

Strategy Design Pattern
Define a family of algorithms, encapsulate each one, and make them interchangeable. Strategy lets the algorithm vary independently from clients that use it.


Problem:
Client wants to decide at run-time what serialization it should use to serialize a type. Many different serialization algorithms are already available.
Solution:
Encapsulate the different serialization algorithms using the Strategy pattern!
C# Code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace StrategyPattern
{

    public interface ISerializer
    {
        void Serialize();
    }
    public class XmlSerializer : ISerializer
    {
        public void Serialize()
        {
            Console.WriteLine("Xml serilizer Invoked");
        }
    }
    public class JsonSerializer : ISerializer
    {
        public void Serialize()
        {
            Console.WriteLine("Json serializer Invoked");
        }
    }
    public class Context
    {
        private ISerializer _serializer;
        public Context(ISerializer serializer)
        {
            this._serializer = serializer;
        }
        public void Serialize()
        {
            _serializer.Serialize();
        }
    }
    class Program
    {
        static void Main(string[] args)
        {
            Context ctx = new Context(new XmlSerializer());
            ctx.Serialize();
        }
    }
}
