C# Generic Factory

Implement Factory pattern using generics

   public interface IDoWork

  {

      string DoWork();

  }

    Declare an Interface first by abstracting the common  functionality

   Here I am taking the example of DoWork

   public class Manager : IDoWork

  {

    public string DoWork()

    {

        return "Manager Manages School";

    }

  }

    Implement the IDoWork in concrete classes as shown 

    public class Teacher : IDoWork

    {

        public string DoWork()

        {

            return "Teacher teaches student in school";

        }

    }

    public class Student : IDoWork

    {

        public string DoWork()

        {

            return "Study in school";

        }

    }

This class will actually create an instance of the concrete class so that you can work on that        object further

    public class FactoryDemo

    {

        public T CreateFactroy<T>() where T : class

        {

            var type = typeof(T);

            return Activator.CreateInstance(type) as T;

        }

    }

In client you can test as shown below

         static void Main(string[] args)

        {

            //bool isWindows = true;

            //var res = DBConnect(isWindows);

            //Console.WriteLine(" Connection - " + res.ToString());

            FactoryDemo create = new FactoryDemo();

            IDoWork obj = create.CreateFactroy<Teacher>();

            Console.WriteLine(obj.DoWork());

            obj = create.CreateFactroy<Student>();

            Console.WriteLine(obj.DoWork());

            obj = create.CreateFactroy<Manager>();

            Console.WriteLine(obj.DoWork());

            Console.ReadLine();

        }
