programmatic defined # foreach loops c#

Question

Here are two examples :

I have an array with 3 items : Universe, planet and Continent I want to use a foreach loop like this :

  foreach(var universe in Universe)
  {
       foreach(var planet in Planet)
       {
             foreach(var continent in Continent)
             { 
                 // here comes my code
              } } }

In this case the array contains 3 elements and therefore I need 3 foreach statements.

Now lets say that I add 2 extra items to the array (Country and State) There would have to be 5 foreach loops.

But what if the array contains 600 items : then I would need to write 600 foreach statements...

So how can this be programatically solved?

• Dynamic code addition?
• Recursive codes (I have no experience with them)
• ...

Answer 1

If you have one array with three items in it, then in order to enumerate through the items you should only need one foreach loop.

List<Object> items = new List<Object> { Universe, Earth, Continent };
foreach (var item in items) { ... }

You would only need to write additional nested foreach loops if the objects contained by the outer array each themselves implemented IEnumerable , and you needed to enumerate these as well. Without seeing the problem that you are trying to solve, it is hard to make a recommendation. But I think that the assumption that you need to have nested foreach structures is incorrect.
