Static Polymorphism in C#

Static or Compile time Polymorphism:

• The method is to be called is decided at compile-time only. Method overloading is an example of this.
• Method overloading is a concept where we use the same method name many times in the same class,but different parameters. 
•  Depending on the parameters we pass, it is decided at compile-time only.
•  The same method name with the same parameters is an error and it is a case of duplication of    methods  which C# does not permit.
•  In Static Polymorphism the decision is made at compile time.

    

Example:

public Class StaticDemo
{
    public void display(int x)
   {
     Console.WriteLine("Area of a Square:"+x*x);
   }
   public void display(int x, int y)
  {
    Console.WriteLine("Area of a Square:"+x*y);
  }
   public static void main(String args[])
  {
    StaticDemo spd=new StaticDemo();
    Spd.display(5);
    Spd.display(10,3);
  }
}
