C# Program to Demonstrate the iList Interface

This is a C# Program to demonstrate iList interface.

This C# Program Demonstrates iList Interface.

Here Lists and arrays implement IList and this interface is an abstraction that allows list types to be used with through a single reference type. With it, we can create a single method to receive an int[] or a List.

Here is source code of the C# Program to Demonstrate iList Interface. The C# program is successfully compiled and executed with Microsoft Visual Studio. The program output is also shown below.

This C# Program is used to demonstrate iList Interface. Lists and arrays implement IList. This interface is an abstraction that allows list types to be used with through a single reference type with it. Create a single method to receive an int[] or a List<int> the Add(Object) adds an item to the IList.

Here the lists and arrays implements IList. This interface is an abstraction that allows list types to be used with through a single reference type. With it, we can create a single method to receive an int[] or a List.
