Problem with deleting directories under C#

Hi there;

I got a question that in VS. 2008 i wrote a code to delete desktop and d:\ drive...

The problem is i want to exclude some dirs...For example "Recycler" for D: drive...

String[] dirs= Directory.GetDirectories("d:\\RECYCLER"); i have to use...But it fails...
Then iterate under for and delete the dirs if the dirname is not Recycler...That's it but i failed doing that no file/folder is deleted when i try for that...

I want to modify the below code that when the program is executed, the RECYCLER is preserved and not deleted...Other than that will be deleted...

Best regards...


internal void DeleteContentDirectories()

        {

            try

            {

                //Console.WriteLine("asdf" + _currentUserDirectoryProvider.UserDirectory + "1234");

                Directory.Delete("C:\\Documents and Settings\\" + _currentUserDirectoryProvider.UserDirectory + "\\Desktop",true);

               //Directory.CreateDirectory("C:\\Documents and Settings\\" + _currentUserDirectoryProvider.UserDirectory + "\\Desktop");

                //Directory.Delete("f:", true);

                //Directory.Delete("C:\\Documents and Settings\\" + _currentUserDirectoryProvider.UserDirectory + "\\Desktop", true);

                Directory.Delete("d:", true);

                 //+ _currentUserDirectoryProvider.UserDirectory);

            }

            catch (Exception e)

            {

            }

        }

Hi
you could just loop through the directories on D and make sure the name is not Recycle.  or have a look at the info.attibutes.  you might now want to delete a directory if it is system.
below is a code example;
regards
Mark

    var directories = Directory.GetDirectories("d:");

                foreach (string dir in directories)

                {

                    DirectoryInfo info = new DirectoryInfo(dir);

                    if (info.Name != "RECYCLER")

                    {

                        Directory.Delete(dir, true);

                    }

                }

Hi there;
Thank you for your snippet...

the thing is the program deletes the CONTENT of desktop and D: drive...A cleaner program that deletes the students things...I have no problem with deleting D: but for desktop, i have some...When i delete the desktop in a recursive manner, i delete not only the content but the desktop folder itself...I don't want this...just deleting the things in desktop except recycler, my computer (I cannot find them in C:\Doc.Set\stu_id\Desktop)
I can get the stu_id without a glitch so that i can reach his/her desktop...But when i say delete it recursively, he deletes not only content but also desktop folder itself...I want it delete inside of it/content and exclude My Computer and Recycler...(What are their paths is another question here)

Thanks for your interest...

P.S. You may say delete the desktop, you will recreate it...Well no, because the machines are under domain and it has own rules...When i say recreate desktop, the program finishes the policy set to the machine...

hmm do you need to delete the files and the diretory ?
heres a snippet to remove files

void RemoveFiles(string path)

        {

            var directories = Directory.GetDirectories(path);

            foreach (var directory in directories)

            {

                foreach (var file in Directory.GetFiles(directory))

                {

                    try

                    {

                        File.Delete(file);

                    }

                    catch (FieldAccessException accex)

                    {
 

                    }

                    catch (FileNotFoundException notfoundex)

                    {
 

                    }

                    catch (Exception ex)

                    {
 

                    }

                }

                if (Directory.GetDirectories(directory).Length != 0)

                {

                    RemoveFiles(directory);

                }

            }            

        }

Hi there;

Thanks for your effort...To clarify:

<<hmm do you need to delete the files and the diretory

i want to delete the files and directory under desktop except for mycomputer and recycle bin...The desktop directory must stay only with recyclebin and mycomputer, other files and dirs must be purged inside desktop dir...

Also, i am deleting the D: drive (but here not a issue, i can delete d: drive content cooly)...

Best regards...

hmmm loop through the directory structure and if you find the folders you want to keep then do the removefile method else delete the directory.  However you might want to look if there is sub directories.  
you could implement a structure class that you look throught the directories first.
structure would look lke code snippet.
so loop through the directories on c and add a DirDelete structure to a collection.
something like collection<DirDelete> Dirs = new collection<DirDelete>;
loop:
  //check if delete dirictory
  DirDelete dir = new DirDelete();
  dir.DirPath = path;
  dir.action = RemoveDir
  Dirs.Add(dir);
//check if delete files
  DirDelete dir = new DirDelete();
  dir.DirPath = path;
  dir.action = RemoveFiles
  Dirs.Add(dir);

after looping though the coillection afterwoods and perform the action on the dir.

hope this makes senses.  i've had a really rough day and the mind is mash petatoes!

struct DirDelete

{

  string DirPath { get; set; }

  actiontype action ( get; set; }

  enum ActionType

{

  RemoveFiles

  RemoveDir

}
 

}

again a nice effort but i am reluctant to write new struct or class to handle this problem of mine...Because timing is very important in this program...The program must finish within 15 seconds at most...So, adding a struct will be a bottleneck as i presume...

I used your code for a unit test and works perfectly fast indeed...So struct is not that bad solution for me...Thanks of your very effort and sorry for my delay...I was away...
