Hi Renu!
I think method variables are more efficient as there scope are limited,they get created only when they required and get destroyed as method scope reaches but the same point is responsible for the major disadvantage of global usage!

Ranchers correct me if am wrong!

With Best Regards!

More important than performance are other considerations - mainly, the principle that you must "keep variables as local as possibile".

This is not uniformly so. If you have constant data germane to various member functions, you might want to declare the data as a static instance variable. In this way, only one copy of the data is made when the class is loaded.
 
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
