static vs instance members in C Sharp

Static Versus Instance Members in C#

• By default, members are per instance
• Each instance gets its own fields
• Methods apply to a specific instance
• Static members are per type
• Static methods can’t access instance data
• No this variable in static methods

  Static methods

     public class Area
  {
    private int side;

    public Rectangle(int side)
    {
        this.side= side;
    }

    public void Area()
    {
        Console.WriteLine("Area output: " + Area.CalculateArea(this.side));
    }

    public static int CalculateArea(int side)
    {
        return side* side;
     }
  }
