How do I create immutable collections in C#?

In C#, you can create immutable collections using the System.Collections.Immutable namespace. Would you like an example?

Yes, please provide an example of an immutable list.

Sure! You can create an immutable list like this:

using System.Collections.Immutable;

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

This creates an immutable list containing the numbers 1, 2, and 3.

Can I add items to this immutable list?

No, you cannot modify an immutable list directly. However, you can create a new list with additional items using the Add method:

var newList = immutableList.Add(4);

This creates a new immutable list with the item 4 added.

What other types of immutable collections are available?

Besides immutable lists, you can also use immutable dictionaries, sets, and queues. Would you like to know more about any specific type?
