Select items from a collection based on the sub-class type in the collection

Question

class A {}
class B : A {}
class C : A {}

ICollection<A> myCollection;
var myresults = myCollection.Where(item => item.GetType() is C);

Given the hierarchy above the where predicate effectively does nothing.

How can I structure the where predicate to return all items of type C from the collection?

Answer 1

而不是在哪里可以使用OfType<TResult>

var myresults = myCollection.OfType<C>();
