How to navigate a few folders up

Question

One option would be to do System IO Directory GetParent   a few times  Is there a more graceful way of travelling a few folders up from where the executing assembly resides   What I trying to do is to find a text file that resides one folder above the application folder  But the assembly itself is inside the bin  which is a few folders deep in the application folder

If you know the folder you want to navigate to  find the index of it then substring               var ind   Directory GetCurrentDirectory   ToString   IndexOf  Folderame                 string productFolder   Directory GetCurrentDirectory   ToString   Substring 0  ind

This is what worked best for me   string parentOfStartupPath   Path GetFullPath Path Combine Application StartupPath             Getting the  right  path wasn t the problem  adding       obviously does that  but after that  the given string isn t usable  because it will just add the       at the end  Surrounding it with Path GetFullPath   will give you the absolute path  making it usable

Other simple way is to do this   string path     C  Folder1 Folder2 Folder3 Folder4   string newPath   Path GetFullPath Path Combine path                 Note This goes two levels up  The result would be      newPath     C  Folder1 Folder2

I have some virtual directories and I cannot use Directory methods  So  I made a simple split join function for those interested  Not as safe though   var splitResult   filePath Split new                StringSplitOptions RemoveEmptyEntries   var newFilePath   Path Combine filePath Take splitResult Length - 1  ToArray       So  if you want to move 4 up  you just need to change the 1 to 4 and add some checks to avoid exceptions

Maybe you could use a function if you want to declare the number of levels and put it into a function   private String GetParents Int32 noOfLevels  String currentpath         String path            for int i 0  i lt  noOfLevels  i                    path                        path    currentpath       return path      And you could call it like this   String path   this GetParents 4  currentpath

The following method searches a file beginning with the application startup path    exe folder   If the file is not found there  the parent folders are searched until either the file is found or the root folder has been reached  null is returned if the file was not found   public static FileInfo FindApplicationFile string fileName        string startPath   Path Combine Application StartupPath  fileName       FileInfo file   new FileInfo startPath       while   file Exists            if  file Directory Parent    null                return null                    DirectoryInfo parentDir   file Directory Parent          file   new FileInfo Path Combine parentDir FullName  file Name              return file      Note  Application StartupPath is usually used in WinForms applications  but it works in console applications as well  however  you will have to set a reference to the System Windows Forms assembly  You can replace Application StartupPath by Path GetDirectoryName Assembly GetExecutingAssembly   Location  if you prefer
