Giving Folder REad/Write permission in server using asp.net

Hi to all...


I need to set folder permission programmaticcaly which is in my GoDaddy server. I have nearly 150 folders in my server so I cant change through server settings or IIS settings. I am using web application.  My folder may go on increase in future.I have googled a lot of things.


1. Like Access Control List in System.SEcurity namespace
2.System.principl.security...
I cant able to change the file permission but not a directory.


I must allow all the users to write or move a file to the folder which is in read only mode. That should be done programmatically and should be dynamic.


I am bit confused and trying to gather from many peoples....


Thanks in advance .... :)
