Simplest way to determine if class x is derived from class y? (c#)

Question

Is this the simplest way to determine if foo is the same or derived from type T

bool Derives<T>(object foo)
{
  return foo is T;
}

and an exact match would be

bool ExactMatch<T>(object foo)
{
  return foo.GetType() == typeof(T);
}

Does the answer have to take interfaces into account (e.g. is `ArrayList` derived from `ICollection`? Is `ICollection` derived from `IEnumerable`?)? Does it have to take generics into account? If so, how should it handle the generic type parameters (e.g. is `List` derived from `IList`? Is `List` derived from `List`?)? — Jon, May 10 '11 at 10:54

I can't think of a simpler way :)

(and in 'answer' format, to please the trolls: "Yes")
