How to enable sharing of internet connections in C #

Question

I worked at Googling and searched on stackoverflow, but none of them give a simple and direct answer to

How to check the box to allow other network users to connect through this Internet connection to a computer and select a network location from the comboBox menu programmatically in C #.

I have successfully created a hosted network through C #, but in the last few days I have been stuck on how to share the Internet through this hosted network through C #.

Please, help.
