Hi,
Am having a base class that implements an interface (air code) :
class BaseClass : SomeInterface
{
void SomeInterface.I mplMethod()
{
// -- code here --
}
}
class Derived : SomeInterface
{
void SomeInterface.I mplMethod()
{
//NEED TO CALL BASE'S IMPLEMENTATION HERE
// -- code here --
}
}
Without making the implementations public, is there a way to do it?
TIA

The derived class doesn't inherit from the base class?
However, even when inheriting, I couldn't find a way to call the base
class interface function. Maybe someone else knows how to do it?
I only found this work-around, by moving the code to a helper function.
Like this:
interface SomeInterface
{
void ImplMethod();
}
class BaseClass : SomeInterface
{
protected void Method() { /* Code goes here */ }
void SomeInterface.I mplMethod() { Method() }
}
class Derived : BaseClass, SomeInterface
{
void SomeInterface.I mplMethod() { base.Method(); }
}
Greetings,
Wessel
>Without making the implementations public, is there a way to do it?
Your naming is a bit confusing since Derived doen't derive from
BaseClass. But you can do
SomeInterface si = new BaseClass();
si.ImplMethod() ;
if that's what you want.

Please reply only to the newsgroup.
You could make the method internal if both classes are in the same assembly
or you really derive from that class and make the method protected.

Thanks for the reply. I missed out on mentioning the base class inheritance
in the derived class.

Greetings, Wessel
Just one Q. The line, void SomeInterface.I mplMethod() { Method() }
would call the most derived version's method, right? I mean there is no
"MyClass" keyword in C# :(
TIA

C# does have a "MyClass" keyword: this. You could write:
void SomeInterface.I mplMethod() { this.Method() }

That doesn't work. Try it.

Why this would be a problem?
In the code of Wessel Troost BaseClass.Metho d is not virtual, so there never
will be a more derived version.

Hello,
I have read that the base keyword can be used not only to control a base
class instantiation (thus calling one of the base class constructors) but
also to access any other public or protected method in the parent class ...
I have search all over for an example of how to do this but have failed.
What I was wondering is about the syntax necessary to make such a call .....
Thx..
