Hello
If you are using impersonation, simply attempting to access the file by
openning it and catching the SecurityException can determine if the current
user has access or not.
This is a simple way, but not the most efficient. But you can cache the
results. For example, cache an array of files that the user can access, for
use in your menu.
bool HasFileAccess(string filename)
{
try
{
FileStream fs = new FileStream(filename, FileMode.Open,
FileAccess.Read, FileShare.ReadWrite);
fs.Close();
return true;
}
catch(SecurityException)
{
return false;
}
}
Otherwise I don't know of another way, except using Interop and calling
windows security API. Note that the above bethod will not work if you are
not using impersonation (i.e. the code is executing with the ASPNET
account).
Best regards,
Sherif

thanks for the info! However, I don't know how this should help in my
case. I *do* know that the WorkerProcess will check if the requested resource is
accessible when the page is requested. But I'd like to be able to
*programmatically* check permissions to a specific resource.
I'm using the Infragistics WebMenu component to have a nice menu. However,
some users don't have access to certain pages linked to by the menu. So,
I'd like to enumerate the menu items and see if the user does have access,
and if not disable the linked menu item.
In ASP, I would have used the permission checker component to check this;
I'm in need of a .NET way to do this...
Thanks!
Jens
