nothing. Otherwise, get the id from the casted type.
2. If there is no target type known-in-advance, for example you don't want
to list all possible target types or it is created by third party, you can
use template constrain in definition. Some thing like this:
bool Comparer (T t1, T t2) where T : IIDBase
{
return t1.Equals(t2);
}
IIDBase is the interface:
Interface IIDBase
{
int GetID();
}
Then derive a |
