After following through some of the links on the page for the access
function, wouldn't the System.IO.FileInfo class with its .Exists,
.IsReadOnly, etc members come the closest in functionality? I don't
know how you would do write only, but if you figured that out, you
could find out read and write as well. access also works on
directories as well, so you might have to go with
System.IO.FileSystemInfo, or check whether the item was a directory or
file before checking the access.
