Want To retrieve string from my array [closed]

Answer 1

Split it into defined parts but you need to use a list:

public static IEnumerable> Split(this IEnumerable list, int parts)
        {
          return list.Select((item, index) => new {index, item})
                       .GroupBy(x => (x.index + 1) / (list.Count()/parts) + 1)
                       .Select(x => x.Select(y => y.item));
        }
