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();
        }

UML - Association, Aggregation, Composition, Generalization, Specialization, Realization and Dependency

Association Association is a simple relationship between two classes. For example A relationship between Professor Class and Student class is known as Association. Both Classes can exist without each other, so Professor and Student are two independent classes. In this kind of relationships there will not be any owner class. Both classes have their own life cycle. UML Notation:     Aggregation Aggregation is a special type of Association. It is known as “Has-A” relationship. For example A Department class can contain Professor Class. Here Department class is owner class. Here in this relationship even after deleting Department class, Professor Class can exits. UML Notation: Composition Composition is a special type of Aggregation. It is known as “Is-A” relationship. For example A University Class has many Department class. Here University and Department objects are dependent on each other. If we delete University cl
