Thetype exposes the following members.
|AsParallel||Enables parallelization of a query. (Defined by ParallelEnumerable.)|
|AsQueryable||Converts an IEnumerable to an IQueryable. (Defined by Queryable.)|

The interface is the base interface for classes in the System.Collections namespace.
The interface extends IEnumerable; IDictionary and IList are more specialized interfaces that extend . 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.
For the generic version of this interface, see System.Collections.Generic.ICollection<T>.
