Mahesh:  I just saw you message this Monday morning.  The problem you are 
having is a bug in the .Net wrapper. I fixed it long ago but have never 
been able to get the new version posted to the shapelib site.  I am 
sending the correct version to you by private message.

Best regards,

David Gancarz

Exact error message is: Object reference not set to an instance of an 
For now, I am checking for shapeObject != null and also wrapped this in a 
try catch block. It did not make any difference. I am fighting with this 
problem for the last 3 weeks. Appreciate your response at the earliest.
Thank you,
