C# dictionary uniqueness for sibling classes using IEquatable<T>
- by anthony
I would like to store insances of two classes in a dictionary structure and use IEquatable to determine uniqueness of these instances. Both of these classes share an (abstract) base class. Consider the following classes:
abstract class Foo
{
...
}
class SubFoo1 : Foo
{
...
}
class SubFoo2 : Foo
{
...
}
The dictionary will be delcared: Dictionary<Foo, Bar>
Which classes should be declared as IEquatable? And what should the generic type T be for those declarations? Is this even possible?
