Abstract class using an interface

[Abhilash]

hi,

My requirement is that there is an interface and want to implement some
of the methods of this interface and the rest will be implement by the
classes which derive from it

Ex

Interface I
{
method m1();
method m2();
}

abstract class A implement I
{
sealed method m1()
{
// Implement something that every body will use and cannot be
changed in sub class
}
abstract method m2();
}

class B :A
{
method m2()
{
//user does his own work
}

}

How can this be acheived?

That's pretty much it ain't it? Of do i misunderstand the question?

why use an interface at all? If you have a base method, why not just use a
virtual base class?

I see the point.. I am using abstract currently which i think is the
same as what you suggesting me to do. But i have to use two abstract
classes because only in the second one am i able to specify the method
as sealed

Well yes... In fact the solution i have taken because i couldnt do the
above was to use two abstract classes. I had to use 2 because only in
the second one was i able to specify the coding of my sealed method.
