file directory structure change

[jassie]

In a C# 2008 desktop application I would like to know how to change the following code so that the files I am looking for can be located.

                 string Format_Date = DateTime.Now.AddMonths(-1).ToString("MM-yyyy");
                     String filesaveLocation = null;
                     filesaveLocation = Path.Combine(ConfigurationSettings.AppSettings["tLocation"], Format_Date);
                     if (!Directory.Exists(filesaveLocation))
                     {
                         System.IO.Directory.CreateDirectory(filesaveLocation);
                         logging.Error("The location " + filesaveLocation + " does not exist.");
                         return packageId;
                     }
 
                    else
                     {
                        string[] RFiles = (from path in Directory.GetFiles(filesaveLocation)
                                              let name = Path.GetFileName(path)
                                              where name.EndsWith(".pdf") ||
                                              name.EndsWith(".xlsx") ||
                                              name.EndsWith(".xls")
                                              select path).ToArray();
                        
                      }
                         foreach (String RFile in RFiles)
                       {
                       }

The code was written for a directory path that looks like the following:
C:\Trans\01-2013 -Note the 01-2013 is for month and year.

Now I am finding out that the file directory stucture in production looks like the following:
R:\Trans\_JAN_2013\A-Sample. Under the A-Sample directory there are 4 separate subdirectories
called: SUB1, SUB2, SUB3, and SUB4.

I was expecting to see the files in one directory instead of 4 separate directories.

Thus can you show me code and/or tell me how you would change the code to accomodae the change in the file directory strucutre?

The Directory.GetFiles method allows you to specify whether to look in just the specified folder or subfolders also. If that's not specific enough then just write a method that takes a folder and returns the files and then call that method multiple times for the multiple folders, adding each file list to a larger list.
