Frozen Collection In C#

In this article, we will discuss the frozen collection in C#.

Purpose

The frozen collection provides an immutable read-only collection for faster lookups and enumeration.

The cost of creating a frozen collection is relatively high, but provides a good lookup performance.

Example

using System.Collections.Frozen;

List<int> normalList = new List<int> { 1, 2, 3 };
FrozenSet<int> frozenSet = normalList.ToFrozenSet();

foreach(int item in frozenSet)
    Console.WriteLine("Item is:"+ item);
