We have web site that used the IIS ResKit tool MSWC.PermissionChecker to
check file permissions. The web site has been upgraded and that upgrade
included changing the default server side language from VBScript to C#
(*.vbs --> *.cs).

Does C# have a native method for doing what MSWC.PermissionChecker used to
do?
If so has anyone gone through converting the MSWC.PermissionChecker method
to C# and would they share what they did?
If not has anyone converted the MSWC.PermissionChecker vbs code to C# and
would they share what they did?

I have posted the old code (some wrapping did occur) hoping it may help you
help me. if more information is need just ask me.

Thanks!

I would strongly suggest not to use this component, it was designed to be
used from asp and as such a STA COM component. ASP.NET runs by default as a
MTA host and using such components will require you to run in (a less
performant) aspnet compatibility mode.
If you need to know if a certain account has Read permissions for a file
(which is not needed when your site is configured correctly and you have an
authentication scheme in place) , simply open the file in read mode and
close it while impersonating.
