Current Context File Access Type in .NET 2

[Davie]

How can I implement a function to show what kind file security access the
current context has on a file, for example:-


public enum AccessType
FullControl
Modify
Read
Write
end enum

private function GetAccess(pathStr as string) as AccessType
...
end function

Hope this explains.

I know I could wrap code inside a try catch block, but this seems a little
expensive. Hopefully there is something in the new FileSecurity features in
..NET that does this a little smarter.

Any help would be greatly appreciated.

Take a look at System.Security.AccessControl
http://msdn2.microsoft.com/en-US/library/system.security.accesscontrol.aspx

File.GetAccessControl http://msdn2.microsoft.com/en-US/library/8e1fc3b8.aspx
is probably the specific method you are looking for (and includes an
example of adding/removing).
