What are some examples of immutable collections in C#?

In C#, immutable collections are collections that cannot be modified after they are created. Examples include ImmutableList, ImmutableArray, and ImmutableDictionary.

Can you show me how to create an ImmutableList?

Sure! You can create an ImmutableList like this:

using System.Collections.Immutable;

var immutableList = ImmutableList.Create<int>(1, 2, 3);

How do I add an item to an ImmutableList?

You can't modify an ImmutableList directly, but you can create a new one with the added item:

var newList = immutableList.Add(4);

What are the benefits of using immutable collections?

Immutable collections provide thread safety, easier reasoning about code, and can help prevent bugs related to unintended modifications.
