C# extension method

Comment

/*
-Extension methods are methods that can be inserted into existing types without creating a new derived type, recompiling,
or otherwise modifying the original type.
-Extension methods are static methods, but in C# they are called as if they were normal C# methods.
They use this modifier in their parameters.
-C# already includes a LINQ library extension method based on the IEnumerable interface, and any class that inherits from this interface, such as an array or list.
But if you want to add a new function to any data type, you should make a static class and add any static method as an extension method.
*/
//EX We want to add a print method that can print any type of array.

//First step to create static class

public static class Extensiton {
  //create your function =should be static, and this keyword must precede the method parameter.
  public static void Print < T > (this T[] array) {
    foreach(var item in array) {
      Console.WriteLine(item);
    }
  }
}

//calling Fucntion 

public class Program {
  static void Main(string[] args) {
    var numbers = new int[] {
      1,
      2,
      3,
      4,
      5
    };
    var fruits = new [] {
      "orange",
      "banana",
      "lemon",
      "grabs"
    };
    //print numbers
    numbers.Print(); // 1 2 3 4 5
    //print fruits
    fruits.Print(); // orange banana lemon grabs

    //notice this keyword replace parameter as without extension method you will do this Print(fruits) or Print(numbers)

  }

}
