private static string return_with_comma(string line)
    {
        line = line.TrimEnd();
        line = line.Replace("  ", ",");
        line = Regex.Replace(line, ",,+", ",");
        string[] array;
        array = line.Split(',');
        for (int x = 0; x < array.Length; x++)
        {
            line += array[x].Trim();
        }
        line += "\r\n";
        return line;
    }
 string result = return_with_comma(test);
 //Output is
 //YK,002,10,23,30,5,TDP_XYZ
