Answer / raju

C# doesn't support multiple inheritence but multilevel
inheritence is allow here(or by using Abstract classes).So
now u can use the Interface Concepts.Taking an example of
how u can inplement that.

//Abstract class of Animal is define here..
abstract class Animal
{
public void Eat()
{
}
}
//Abstract class of Vechicle is define here..
abstract class Vechicle
{
public void Eat()
{
}
}
//Implementing Interface....
Interface Flyer
{
void Fly();
}

class Aeroplane:Vehicle,Flyer
{
}

class Bird:Animal,Flyer
{
}

As you can see, the two sub classes Bird and Aeroplane
derive from the Animal and Vehicle classes respectively.
Both have the characteristics of their respective base
classes. The Bird like any other animal, eats while the
Aeroplane being a vehicle, runs. However, they both share a
common trait - the ability to fly. This ability is neither
possessed by all animals nor by all vehicles. So it cannot
be defined in either of the base classes. Again, it is not
only possessed by the Aeroplane and Bird, some insects,
baloons and other types of vehicles such as the Helicopter
also possess it. It wouldn’t be effective to define this
ability in each of them. Actually, it will be defined
individually in each of these classes because each have
their own way of flying, the bird flaps the wings, whereas
the helicopter roatates its through a mechanical engine.
However, this ability is declared in the Flyer interface so
that any class which implements this interface would have
to define the Fly() method by overriding it.

Answer / gopal

Creating a new class from an existing class is known as
inheritence.
Multilevel inheritence:
Creating a new class from already Derived Class is
known as Multilevel Inheritence.

Answer / venkat

.Net Frame work does not support Mltiple inheritance but it
supports Multiple Interface inheritance.Because one class
can derive from only one base class but from multile
interfaces
