As far as I can determine, specializing the member function only works if it has a single template parameter, like so:

Can anyone explain how I can apply this logic to the case of multiple template arguments? The following code, by way of example, does not compile.

template< class X, int N >
class Foo
{
public:
int GetNumber() const { return 42; }
};

template < class X, int N >
int Foo< X, N >::GetNumber() const { return 42; }

template < class X >
int Foo< X, 5 >::GetNumber() const { return 69; }
