Alvin Bruney said:One way is to create an assembly that has an attribute that demands the
fileIOPermissionAccess permission. Inside the assembly, you can create a
method that does the dirty work. The downside with this is that the entire
class has the permissions, if you want to restrict it to just a method,
you can demand the permission thru code. There's a link with an
implementation sample here:
http://msdn2.microsoft.com/en-us/library/system.security.permissions.fileiopermission.aspx.
Read the pre-requesits VERY carefully. These are strong permissions you
are asking for and there is a very real potential for you, your code, or
rogue code to subvert or compromise the sub-system.

permission to execute a Environment.SpecialFolder.ApplicationData
method ?
thanks Brian,
Brian Stoop said:Alvin,
It is the FileIOPermissionAccess.PathDiscovery permission I want to set.
(I'm trying to get the value of
Environment.SpecialFolder.ApplicationData)
In the msdn examples we get::
FileIOPermission f2 = new FileIOPermission(FileIOPermissionAccess.Read,
"C:\\test_r");
f2.AddPathList(FileIOPermissionAccess.Write | FileIOPermissionAccess.Read,
"C:\\example\\out.txt");
But I cannot figure out the call to set PathDiscovery permission as it has
no path?, and there appears to be no signature for it?
thanks, B
