Classes

Class

• Building Block of Software Application

Anatomy of Class

• Data : Represented by field
• Behavior : Represented by Methods and Functions

---

UML(Unifying Modeling Language)

• Used to illustrate a class

• It Consist of three part

  • Class Name
  • Class Properties
  • Class Methods or Function

  Class Example

  internal class Program
      {
          private static void Main(string[] args)
          {
              var p = new Person();
                  p.Name = "Vivek";
              p.Introduce();
  
          }
      }
  
      public class Person
      {
          public string Name;
  
          public void Introduce()
          {
              Console.WriteLine($"Hello My Name is {Name}");
          }
      }
  

  Class Members

  • Instance Type : Accessible with instance of object

    • Sample Code

                var p = new Person();
                      p.Name = "Vivek";
                  p.Introduce();
      

  • Static Type : Accessible from Class

    • Sample Code

      console.writeline();
      

  Why Use Static Type Members

  • To Represent Concept such as singleton
  • for example Current Day time
