Thanks a lot Peter. I appreciate your Help. You mentioned that C# code above is
not good. If you can point me why it is not good, would help me learn new
approaches as this type of Code I use to see long back(when i was fresher).
There may be better approaches or concepts i am not aware of. If you can point
me in that direction it would be gr8.
