It extends the IEnumerable interface and provides the facility to define size, synchronization method and enumerator.ICollection has some properties and methods. Use the Add () method or object initializer syntax to add elements in an ArrayList . An ArrayList can contain multiple null and duplicate values. Use the AddRange (ICollection c) method to add an entire Array, HashTable, SortedList, ArrayList, BitArray, Queue, and Stack in the ArrayList . Collections are based on the ICollection interface, the IList interface, the IDictionary interface, or their generic counterparts. The IList interface and the IDictionary interface are both derived from the ICollection interface; therefore, all collections are based on the ICollection interface either directly or indirectly. Method 1: ICollection ids = new List(); Method 2: List ids = new List(); First of all: You create the same object, a List in both cases.
