Compile-time Polymorphism

Compile-time Polymorphism in C#

Compile-time polymorphism, also called static polymorphism, means that the method to be executed is decided during compile time. It is mainly achieved through method overloading in C#.

Features:

• Decided at compile time
• Achieved using method overloading
• Occurs within the same class
• Faster than runtime polymorphism

C# Example:

class Calculator { public int Add(int a, int b) { return a + b; } public double Add(double a, double b) { return a + b; } public int Add(int a, int b, int c) { return a + b + c; } } class Program { static void Main() { Calculator c = new Calculator(); Console.WriteLine(c.Add(2, 3)); Console.WriteLine(c.Add(2.5, 3.1)); Console.WriteLine(c.Add(1, 2, 3)); } }
