Explicit Interfaces and overriding methods

I know that I can't declare a method in an interface as virtual and override
it, when I am using an explicit interface, but I am wondering if anyone else
has come across this problem and how they handled it? I would definately
prefer to use explicit interfaces, but I also know I shouldn't mix and match
explicit versus implicit interfaces and don't seem to have a choice here?

Any thoughts on this?
 
What I have done is create virtual methods which the explicit interface
definitions just pass the parameters and return values between, for example:

public interface IMyInterface
{
string Op(string param);
}

public class MyClass : IMyInterface
{
string IMyInterface.Op(string param)
{
// Just call the internal method.
return InternalOp(param);
}

protected virtual string InternalOp(string param)
{
// Do work here.
}
}

Hope this helps.
 
Thanks, that is exactly what I needed!
