Accepted answer
When you inherit class A in class B the members of class A except private members becomes the members of class B. This is the main motive of inheritance to reuse the code. When you inherit class B in class C then members of class B including the inherited members from class A becomes the members of class C.

If it helps you accept it as correct answer.

Hey don't confuse two things

Multiple inheritance:

class A
{
}
class B
{
}
class C:A,B
{
}

Multilevel Inheritance:

class A
{
}
class B:A
{
}
class C:B
{
}

The first one is multiple inheritance which is not supported in c#

Hi,
No you are wrong.
class C have only one base class(class B)

if your class like this

Class C : B,A
{

}
in this case class C have two base classes A, B but in C# it does not support like this

But if it is a Multi level Inheritance then ??? Like this.

In Multilevel Inheritance a class can have more than one base class or not ?

Multiple inheritance is not supported in C#. So class can have only one base class. If you want to achieve multiple inheritance, you can achieve it by using interface. You can implements any number of interfaces in C#.

Hi Debasis,

a class can have only one base class . because c# does not support multiple inheritance.

only one base class.
Basically, it seemed that both the .NET and Java designers did not allow multiple inheritance
if you want more class's inheritance use interface
