Milline on IList liidese peamine funktsionaalsus .NET-is ja millistes stsenaariumides on selle kasutamine õigustatud?

The IList interface in .NET represents a collection that supports indexed access to elements, as well as operations for adding, removing, and searching for elements.

The main functionalities of IList include:

• Accessing elements by index (via the indexer).
• Adding and removing elements.
• Searching for the index of an element.
• Inserting elements at a specific position.

IList is suitable for scenarios where an ordered collection with quick access and modification of elements by index is needed.

Example of using IList:

IList<string> list = new List<string>();
list.Add("apple");
list.Insert(0, "banana");
string first = list[0]; // "banana"
list.RemoveAt(1); // removes "apple"

Using IList is justified when working with collections that support dynamic resizing and indexed access, but you want to abstract from the specific implementation of the collection.
