IEnumerable is the base of the ICollection and IList interfaces (and many other). All these interfaces provide various functionalities and are useful in various cases. IEnumerable Interface As we mentioned before when discussing the ICollection interface, there are some more methods defined in the ICollection interface than in the ICollection interface. Therefore the member list of the IList interface is a bit shorter than the non-generic equivalent. Examples.

The returned ICollection is not a static copy. Instead, the ICollection refers back to the values in the original HybridDictionary. Therefore, changes to the HybridDictionary continue to be reflected in the ICollection. Retrieving the value of this property is an O(1) operation. Reference:
