C# Program to Demonstrate Method Hiding

This is a C# Program illustrate method hiding.

This C# Program Illustrates Method Hiding.

Here a method func() in the base class and in the derived class give a completely new definition to the same method by preceding it with ‘new’ keyword

Here is source code of the C# Program Illustrate Method Hiding. The C# program is successfully compiled and executed with Microsoft Visual Studio. The program output is also shown below.

    {
        public virtual double Area(double r)
        {
            return r * r;
        }
        public void func()
        {
            Console.WriteLine("Base Class");
        }
    }
    public class A : Demo
    {
        public override double Area(double r)
        {
 
            return base.Area(r) * r;
        }
        public new void func()
        {
            Console.WriteLine("Derived Class");
        }
    }
    public class Test
    {
        public static void Main(string[] args)
        {
            A o1 = new A();
            Console.WriteLine(o1.Area(20));
            o1.func();
            Console.ReadLine();
        }
    }
}

In this C# program, using new keyword we are creating an object ‘o1’ variable for class A. The method func() in the base class and in the derived class give a completely new definition to the same method by preceding it with ‘new’ keyword.

In Demo class we have created two functions. The Area() function is used for computing an area. Then func() function is used to print the output of the program. Then ‘class A’ inherits the property of Demo class, then compute the area.
