RESOLVED delete a file older than thirty days I am getting a directory Invalid error

[Christopher_Arm]

I placed this code yesterday which focuses on deleting a file older the thirty days and this process checks after my streamwriter code the whole thing looks like this :

 public LoggingAction( GlobalConfiguration globalConfig, PayFilePackageCol paymentfilePackCol)

        {
            GlobalConfig = globalConfig;
            PayFilePackCol = paymentfilePackCol;
            logfilePath1 = this.GlobalConfig.Payment_Log_File_Loc;


      


    



            String folder = Path.GetDirectoryName(logfilePath1);
            String fileName = Path.GetFileNameWithoutExtension(logfilePath1);
            String extension = Path.GetExtension(logfilePath1);

            String newName = folder + "\\" + fileName + "_" + ISO_Date() + extension;

         

            pSW = new StreamWriter(newName, true);



            string[] files = Directory.GetFiles(newName);
            foreach (string file in files)
            {
                FileInfo fi = new FileInfo(file);
                if (fi.LastAccessTime < DateTime.Now.AddDays(-30))

                    fi.Delete();
            } 






        }


        ~LoggingAction()
        {

now the global config. Payment_Log_File_Loc is acutally C:\Temp on my local c drive so unless my permissions are set that I can't delete from there what else could be going on to fire off that exception ?
