How to work with read-only collections in C#

Take advantage of read-only generic interfaces such as IReadOnlyList, IReadOnlyDictionary, and IReadOnlyCollection to prevent modifications to collections in your .NET Core applications.

A collection represents a set of objects used for the storage and retrieval of data. Collections enable you to allocate memory dynamically to store elements and then retrieve them using a key or index as needed.

You can have standard or generic collections. While standard collections don’t provide type-safety, generic collections are type-safe. The standard collections are part of the System.Collections namespace, and the generic collections are part of the System.Collections.Generic namespace.
