In what situations should you use list data structures?

Data structures of the list type (List) in C# should be used when you need to store an ordered collection of elements with the ability to dynamically change its size. Lists are convenient if:

• You often need to add or remove elements.
• Access to elements by index is required.
• The exact number of elements is unknown in advance.

For example, if you are collecting data from a user and do not know in advance how many elements will be entered, a list allows flexible management of this collection.

Example of usage:

List<string> names = new List<string>();
names.Add("Ivan");
names.Add("Maria");
Console.WriteLine(names[0]); // Will output "Ivan"
