How to append an array to a List using LINQ?

Question

I have the following piece of code:

private List<IComponent> _components;

protected void UsePageComponents(params IComponent[] components) => _components = components.ToList();

I receive an array with params and I would like to append this array to the List (_components)`? How do I accomplish this using LINQ?

You don't need LINQ; List<T>.AddRange will do:

protected void UsePageComponents(params IComponent[] components)
{
    _components.AddRange(components);
}

It accepts IEnumerable<T> which T[] implements.
