What are immutable collections in C#?

Immutable collections in C# are data structures that cannot be modified after they are created. This means once you create an immutable collection, you cannot add, remove, or change its elements.

Can you give me an example of an immutable collection?

Sure! An example of an immutable collection in C# is the ImmutableList<T>. You can create it using ImmutableList.Create<T>() and it provides methods to return new collections with added or removed elements without modifying the original.

What are the benefits of using immutable collections?

The benefits include thread safety, easier reasoning about code, and avoiding unintended side effects since the data cannot be changed after creation.

How do I convert a mutable collection to an immutable one?

You can convert a mutable collection to an immutable one using methods like ToImmutableList() or ToImmutableArray() from the System.Collections.Immutable namespace.
