C＃继承与构造函数和覆写

Question

I'm testing this program for inheritance I have 3 classes ( animal,emu,kangaroo) and main class.

emu and kangaroo derived from Animal class.

when I try to run the program getting error Emu.Bird(), Kangaroo.Mamel() is not suitable method found to overide. I'm doing it by a random tutorial and not sure about the "override" and what exactly it does.

static void Main(string[] args)
    {
        Emu e = new Emu("Emu","Brown", "is a bird");

        Console.WriteLine();

        Kangaroo k = new Kangaroo("Kangaroo","Dark Brown", "Is a mamel" );

        Console.ReadLine();
    }

Animal Class

 class Animal
{
    public string name;
    public string colour;

    public Animal(string MyName,string MyColour)
    {
        name = MyName;
        colour = MyColour;
    }

    public virtual void Show()
    {
        Console.WriteLine("Name: "+ name);
        Console.WriteLine("Colour: "+ colour);

    }
}

Emu Class

 class Emu:Animal
{
    public string bird;

    public Emu(string name,string colour, string eBird) : base(MyName,MyColour)
    {
        bird = eBird;
    }

    public override void Bird()
    {
        base.Show();
        Console.WriteLine(bird);
    }

}

Kangaroo Class

  class Kangaroo:Animal
{
    public string mamel;


    public Kangaroo(string name,string colour, string Mamel) : base(MyName,MyColour)
    {
        mamel = Mamel;
    }

    public override void Mamel()
    {
        base.Show();
        Console.WriteLine("Is a bird or Mamel ? " + mamel);
    }
}

Answer 1

The word override in coding means to replace the implementation of an existing method, ie overriding the previous method.

So here in your case, the class that you are inheriting from doesn't have mamel or bird method.

Don't just read random articles..go by series of topics. Refer a book or some tutorial series.

Check if you can pdf version of CLR via C# or you can also refer our ongoing tutorial series at CheezyCode
