How to use interfaces in exception handling

Question

I am working on an exception handling level for my application.

I read several articles about interfaces and generics. I have used inheritance before quite a lot, and I like it in this area.

I have a very short design that I am going to implement:

public interface IMyExceptionLogger
{
   public void LogException();

   // Helper methods for writing into files,db, xml
}

I'm a little confused about what I have to do next.

public class FooClass: IMyExceptionLogger
{

   // Fields
   // Constructors

}

Should I implement a method LogException()inside FooClass? If so, then I'm trying to figure out how best to use an interface instead of a specific class ...

I have many classes that will use this interface, but I do not want to write an implementation of this interface in each class.
