The extension method:

public static void AddRange<T, S>(this List<T> list, params S[] values)
    where S : T
{
    foreach (S value in values)
        list.Add(value);
}

The method applies for all types and lets you add a range of items to a list as parameters.

Example:

var list = new List<Int32>();
list.AddRange(5, 4, 8, 4, 2);
