Question

I feel stupid for asking, but there must be a one liner that does the equivalent or near equivalent of the code below in c#… so can you tell me what it is?

    public static string[] ToStringArray(int[] i)
    {
        if (i==null) return null;
        string[] result = new string[i.Length];
        for (int n= 0; n< result.Length; n++)
            result[n] = i[n].ToString();
        return result;
    }

How about an extension method?

public static string[] ToStringArray<T>(this IEnumerable<T> items)
{
    return items.Select(i => i.ToString()).ToArray();
}
