        public static IEnumerable<string> SplitByLength(this string str, int maxLength)
        {
            for (int index = 0; index < str.Length; index += maxLength)

        static void Main(string[] args)
        {
            string bigText = String.Concat(Enumerable.Repeat("helloworld", 1024*1024)); // 1MB
            string[] bigTextChunked = Tools.SplitByLength(bigText, 32768).ToArray();
            Console.WriteLine("bigText is {0} bytes\nbigTextChunked has {1} elements\nbigTextChunked [0] is {2} bytes", bigText.Length, bigTextChunked.Length, bigTextChunked[0].Length);
        }
    }
}    

output:

bigText is 10485760 bytes
bigTextChunked has 320 elements
bigTextChunked [0] is 32768 bytes
