Simple Chaining... nothing more

Chain.cs

class Chain<T> {

    private Chain() { }

    private readonly List<T> _Chain = new List<T>();

    public static Chain<T> Start => new Chain<T>();

    public Chain<T> this[T This_] {
        get { this._Chain.Add(This_); return this; }
    }

    public T[] End => this._Chain.ToArray();
}
