how do I combine several Action into a single Action in C#?

Question

How do I build an Action action in a loop? to explain (sorry it\'s so lengthy)

I have the following:

public interface ISomeInterface {
    void MethodOn

It's really easy, because delegates are already multicast:

Action<ISomeInterface> action1 = z => z.MethodOne();
Action<ISomeInterface> action2 = z => z.MethodTwo("relativeFolderName");
builder.BuildMap(action1 + action2, "IAnotherInterfaceName");

Or if you've got a collection of them for some reason:

IEnumerable<Action<ISomeInterface>> actions = GetActions();
Action<ISomeInterface> action = null;
foreach (Action<ISomeInterface> singleAction in actions)
{
    action += singleAction;
}

Or even:

IEnumerable<Action<ISomeInterface>> actions = GetActions();
Action<ISomeInterface> action = (Action<ISomeInterface>)
    Delegate.Combine(actions.ToArray());
