Question

What would be the nice way to make the following action:

List<IEnumerable<T>> listOfEnumerables = Get...();

List<T> listOfObjects = new List<T>();

// I want 'listOfObjects' to contain every element from every enumerable
// in 'listOfEnumerables'.

Is there any beautiful way to make this instead of the following:

foreach (var enumerable in listOfEnumerables)
{
    listOfObjects.AddRange(enumerable);
}

Thank you.

You can use LINQ:

List<T> listOfObjects = listOfEnumerables.SelectMany(s => s).ToList();
