C# - Extension Method For ForEach

ForEach Extension for any arbitrary IEnumerable<T> sequence:

// Ex Usage

yourSequence.ForEach(x => Console.WriteLine(x));

// Extension Method

public static class EnumerableExtensions
{
    public static void ForEach<T>(this IEnumerable<T> source, Action<T> action)
    {
        if (source == null) throw new ArgumentNullException("source");
        if (action == null) throw new ArgumentNullException("action");

        foreach (T item in source)
        {
            action(item);
        }
    }
}

If you're dealing with an array then you can use the built-in static ForEach method:
Array.ForEach(yourArray, x => Console.WriteLine(x));
If you're dealing with a List<T> then you can use the built-in ForEach instance method:
yourList.ForEach(x => Console.WriteLine(x));
