Hello!

I would like to apply FileIOPermission on set of files using mask in file name, ex. on all txt files in folder C:\TMP:

[type: FileIOPermission(SecurityAction.PermitOnly, Read = @"C:\TMP\*.txt")]
class SomeClass
{
    static void testPermissions()
    {
        Console.WriteLine("allowed action");
        File.OpenRead(@"C:\TMP\1.txt"); // <--- here goes exception
        Console.WriteLine("denied action");
        try
        {
            File.Create(@"C:\TMP\2.txt");
        }
        catch (Exception e)
        {
            Console.WriteLine(e.Message);
        }
        finally
        {
            Console.ReadKey();
        }
    }
}

This throws ArgumentException "Illegal characters in path."

What is wrong? Is it possible to achieve anyway?
