File Permission System.UnauthorizedAccessExceptionI am trying to modify a file on my computer but I get an error which says the following. "System.UnauthorizedAccessException: Access to the path. I also tried FileIOPermission FileIOPermission fio = new FileIOPermission(FileIOPermissionAccess.AllAccess, paramMP3.fileComplete); FileStream oFileStream; oFileStream = new FileStream(paramMP3.fileComplete , FileMode.Open, FileAccess.ReadWrite); that didn't seem to have any effect on it also. Appreciate any help Thanks Tom Hello Tom,
UnauthorizedException has nothing to do with CAS and FileIOPermission. This is a OS level error - i would say you don't have the necessary NTFS ACLs... --------------------------------------- Dominick Baier - DevelopMentor http://www.leastprivilege.com Show quoteHide quote > Hi friends > > I am trying to modify a file on my computer but I get an error which > says the following.

however I have cheched the application is using administrator as its identity. The effective permission for administrator is full access. I also checked Everyone user and it also has full access under effective permission. I'm really not sure what else could be wrong. Appreciate your help !

what happens if you use a different file? maybe someone has a lock on that file, try to pass in the 4th parameter the FileStream ctor - lockMode or similar and set it to none - just to see what happens... --------------------------------------- Dominick Baier - DevelopMentor http://www.leastprivilege.com Show quoteHide quote > Yes that is my initial thought... > > however I have cheched the application is using administrator as its > identity.
