Interleaving split strings as a list c#

Question

Currently I need to interleave to strings into a singe list, yet am at a loss re how to do it.

The code I'm using currently is this (I haven't gotten very far):

 public PartialViewResult Interleave(string details, string ids)
    {
            List<string> detailList = details.Split(',').ToList();
            List<string> idlist = ids.Split(',').ToList();
            return PartialView("_ConceptDetail1", detailList)     
    }

Is there a standard way to interleave the lists?

Answer 1

Maybe you want to zip both together, you can use Enumerable.Zip then:

String[] details = details.Split(',');
String[] ids = ids.Split(',');
List<String> idDetails = ids.Zip(details, (id, detail) => id + " " + detail)
                        .ToList();

Answer 2

Based on Zip 's implementation, I supposed I would make my own extension method :

    static IEnumerable<T> Interleave<T>(this IEnumerable<T> first, IEnumerable<T> second)
    {
        using (IEnumerator<T> enumerator = first.GetEnumerator())
        {
            using (IEnumerator<T> enumerator2 = second.GetEnumerator())
            {
                while (enumerator.MoveNext() && enumerator2.MoveNext())
                {
                    yield return enumerator.Current;
                    yield return enumerator2.Current;
                }
            }
        }
        yield break;
    }
