.NET interview question – What is Shadowing?

Answer: Shadowing is a concept of altering the behaviour of the base class member.
It basically replaces complete element of the parent class like method
becomes a variable.For example: In the below example in class1 ‘i’ is declared as variable whereas in class2 ‘i’ is declared as a method.

class Program
    {
        static void Main(string[] args)
        {
            class1 obj = new class1();
            class2 obj1 = new class2();
            obj1.i();                 //here i is treated as method
            Console.WriteLine(obj.i); //here i is treated as variable
            Console.ReadLine();
        }
    }
    class class1
    {
        public int i=2;
    }
    class class2 : class1
    {
        public void i()
        {
            Console.WriteLine("Hello World");
        }
    }
