'Extends' and 'Implements' Java equivalents in C#

What is the C# equivalent syntax for the following Java statement:

public class Lion extends Animal implements Diurnal()
{
}

• Animal is Base class
• Diurnal is an Interface

the inheritance could be declared like this.

public class Lion : Animal, Diurnal
{

}

In C#, you can inherit one base class and can be multiple Interfaces.

One more tip, if you are making an Interface in C#, prefix it with I. eg IDiurnal

public class Lion : Animal, // base class must go first
                    Diurnal // then interface(s) if any
{
}

Would look something like this:

public class Lion :Animal, Diurnal {
}

Where Animal is a class and Diurnal is an interface.

Please note, that according to the C# naming convention, interface has to have "I" infront of its name, so finally it should look like this:

public class Lion :Animal, IDiurnal {
}

In C#, there is uniform syntax for extending class and implementing interface.

public class Lion : Animal, Diurnal {

}

you need to write down first base class like(Animal is base class), lately interfaces like as(Diurnal is a Interface)

public class Lion : Animal, Diurnal {}

the first name after : is the extended class, after comes the implemented interfaces

public class Lion : Animal, Diurnal
{
}

c# do not allow multiple class extension, but you can implement many interfaces

public class Lion : Animal, Diurnal
{
}

interface Diurnal
{
}

class Animal
{
}

Class Animal was inherited by Lion class. Diurnal class is interface.
