Split string in 512 char chunks

Question

Maybe a basic question but let us say I have a string that is 2000 characters long, I need to split this string into max 512 character chunks each.

Is there a nice way,

Something like this:

private IList SplitIntoChunks(string text, int chunkSize)
{
    List chunks = new List();
    int offset = 0;
    while (offset < text.Length)
    {
        int size = Math.Min(chunkSize, text.Length - offset);
        chunks.Add(text.Substring(offset, size));
        offset += size;
    }
    return chunks;
}

Or just to iterate over:

private IEnumerable SplitIntoChunks(string text, int chunkSize)
{
    int offset = 0;
    while (offset < text.Length)
    {
        int size = Math.Min(chunkSize, text.Length - offset);
        yield return text.Substring(offset, size);
        offset += size;
    }
}

Note that this splits into chunks of UTF-16 code units, which isn't quite the same as splitting into chunks of Unicode code points, which in turn may not be the same as splitting into chunks of glyphs.
