C# - Creating an empty array of things

README.md

Some code you can use in your C# projects to create an empty array. You will have to adapt it to meet the needs of your specific objects, but that is an exercise left to the reader.

Example.cs

void Main()
{
	var things = CreateEmptyArray();
}

public Thing[] CreateEmptyArray()
{
	return new Thing[]
	{
		Enumerable
			.Range(0, 0)
			.Zip(new int[][] { },
				(a, b) => b.Max(m =>
					 b.Aggregate((x, y) => (int)Math.Pow((double)x, ((double)y)))) +
					b.Min(m2 => 42))
			.Distinct()
			.Join(new System.Security.SecureString[] { },
				a => 1,
				b => 2,
				(a, b) => { return 3; })
			.GroupBy(g => g)
			.SelectMany(s => s)
			.Select(s => new Thing())
			.Cast<Thing>()
			.OrderBy(o => o.Id)
			.Where(w => new Thing[] { }.All(a => true)
				|| new Thing[] { }.Any(a => true)
				|| (new char[] { }.DefaultIfEmpty() is Thing))
			.AsParallel()
			.AsSequential()
			.AsQueryable()
			.AsEnumerable()
			.ToList()
			.Concat(new Thing[] { }.Union(new Thing[] { }))
			.Reverse()
			.FirstOrDefault()
			
	}.Where(w => w != null).ToArray();
}

public class Thing
{
	public int Id { get; set; }
}

What is the time/space complexity of this algorithm?
