Splitting a string into chunks of a certain size

Question

Suppose I had a string:

string str = \"1111222233334444\"; 

How can I break this string into chunks of some size?

e.g., breaking t

I took this to another level. Chucking is an easy one liner, but in my case I needed whole words as well. Figured I would post it, just in case someone else needs something similar.

static IEnumerable Split(string orgString, int chunkSize, bool wholeWords = true)
{
    if (wholeWords)
    {
        List result = new List();
        StringBuilder sb = new StringBuilder();

        if (orgString.Length > chunkSize)
        {
            string[] newSplit = orgString.Split(' ');
            foreach (string str in newSplit)
            {
                if (sb.Length != 0)
                    sb.Append(" ");

                if (sb.Length + str.Length > chunkSize)
                {
                    result.Add(sb.ToString());
                    sb.Clear();
                }

                sb.Append(str);
            }

            result.Add(sb.ToString());
        }
        else
            result.Add(orgString);

        return result;
    }
    else
        return new List(Regex.Split(orgString, @"(?<=\G.{" + chunkSize + "})", RegexOptions.Singleline));
}
