What is the .net equivalent of a java hashbag collection

Question

java hashbag集合的.net等效项是什么，该集合仅存储类似项的一次，但也存储项的出现次数？

Answer 1

See also: Duplicate keys in .NET dictionaries? Another common name for bag is multiset, see also: Are there any implementations of multiset for .Net?

Via those links I found the Wintellect's Power Collections bag implementation. From its source:

Bag<T> is a collection that contains items of type T. 
Unlike a Set, duplicate items (items that compare equal to each other) are allowed in an
Bag.

Not a .net user myself so I don't know if this library is too old to be useful. Hopefully it helps!
