This is one of solution, i dont use any helper class or method.

        public static List ExtractChars(string inputString) {
            var result = new List();
            int startIndex = -1;
            for (int i = 0; i < inputString.Length; i++) {
                var character = inputString[i];
                if ((character >= 'a' && character <= 'z') ||
                    (character >= 'A' && character <= 'Z')) {
                    if (startIndex == -1) {
                        startIndex = i;
                    }
                    if (i == inputString.Length - 1) {
                        result.Add(GetString(inputString, startIndex, i));
                    }
                    continue;
                }
                if (startIndex != -1) {
                    result.Add(GetString(inputString, startIndex, i - 1));
                    startIndex = -1;
                }
            }
            return result;
        }

        public static string GetString(string inputString, int startIndex, int endIndex) {
            string result = "";
            for (int i = startIndex; i <= endIndex; i++) {
                result += inputString[i];
            }
            return result;
        }
