Public Interface ICollection _
Inherits IEnumerable
The ICollection interface is the base interface for classes in the System.Collections namespace.
The ICollection interface extends IEnumerable; IDictionary and IList are more specialized interfaces that extend ICollection. An IDictionary implementation is a collection of key/value pairs, like the Hashtable class. An IList implementation is a collection of values and its members can be accessed by index, like the ArrayList class.
Some collections that limit access to their elements, such as the Queue class and the Stack class, directly implement the ICollection interface.
If neither the IDictionary interface nor the IList interface meet the requirements of the required collection, derive the new collection class from the ICollection interface instead for more flexibility.
For the generic version of this interface, see System.Collections.Generic..::.ICollection<(Of <(T>)>).
