What are the differences between ICollection and IList interface?
Rating:
The differences between ICollection and IList interface are as follows:
| ICollection interface is implemented by all collections to provide the CopyTo() method as well as the Count, IsReadOnly, IsSynchronized, and SyncRoot property. | IList interface is used by array-indexable collections. |
| ICollection interface is used to define size, enumerators, and synchronization methods for all non-generic collections. | IList interface defines a non-generic collection of objects that can be individually accessed by using the index value. |
| ICollection interface is the base interface for all classes in the System.Collection namespace. | IList interface is a descendant of the ICollection interface and is the base interface of all non-generic lists. |
| An ICollection interface can be modified. | A read-only IList interface cannot be modified. |
| An ICollection interface allows the addition or removal of elements. | A fixed-size IList interface does not allow the addition or removal of elements. |
