constructor chaining

.net, c#

Solution

Try:

public CA(string s, int num) : this(s, new List<int>(new int[] { num }))
{
}

This should match the constructor overload which takes an `IEnumerable<T>` (which an array of `T[]` is convertible to).

Problem

Sample code : ``` public class CA { public CA(string s, List<int> numList) { // do some initialization } public CA(string s, int num) : this(s, ListHelper.CreateList(num)) { } } public static class ListHelper { public static List<int> CreateList(int num) { List<int> numList = new List<int>(); numList.Add(num); return numList; } } ``` The second constructor in "CA" uses constructor chaining. Inside the "this" call, I want to convert an int into a List with one member. The code works via the helper function "CreateList", but I'm wondering if there is a cleaner way than this. i.e. is there some way to do it without the helper method. To date, in situations like this, I probably wouldn't bother using constructor chaining. Thoughts ?
