[RESOLVED] [2.0][2005] FTPWebrequest RemoveDirectory

[MadCatVB]

Hi all,

I have been working on an app, part of which connects to a FTP site. I have code working to listdirectories, download and upload files. What i now want to do is delete directories from the FTP server once i have finished with them. I have written this code which is based on the delete file code found on the MSDN site:

public bool DeleteDirectoryOnServer(Uri serverUri)
        {
            // The serverUri parameter should use the ftp:// scheme.
            // It contains the name of the server file that is to be deleted.
            // Example: ftp://contoso.com/someFile.txt.
            // 

            try
            {
                if (serverUri.Scheme != Uri.UriSchemeFtp)
            {
                return false;
            }
            // Get the object used to communicate with the server.
            FtpWebRequest request = (FtpWebRequest)WebRequest.Create(serverUri);
            request.Method = WebRequestMethods.Ftp.RemoveDirectory;
            request.Credentials = m_networkcred;

            FtpWebResponse response = (FtpWebResponse)request.GetResponse();

            Debug.Print(response.StatusCode.ToString());

            Debug.Print("Delete status: {0}", response.StatusDescription);
            response.Close();
            return true;
            }
            catch (Exception ex)
            {
                Debug.Print(ex.Message);
                return false;
            }

            
        }

When running the code i get the following error:

The remote server returned an error: (550) File unavailable (e.g., file not found, no access).

Could anyone shed some light on why this could be happening? I know the directory is there. There is also very little information available on the RemoveDirectory webrequestmethod online.

All help is greatly appreciated.

Thanks,

Grant

RESOLUTION:

I found a resolution for the problem. It appears i can only remove empty directories. I'll need to loop through the contents and delete any files before removing the folder.

no. the problem is still there. i have an empty folder which raises this error.
some body hlp pls

[thinksomid]

here is my code even with loop iteration through folder contents.

public bool deleteFolderContents(string remoteFolder)
{
bool rslt = false;

try
{
string[] list = directoryListSimple(remoteFolder);
List<string> files = new List<string>();
List<string> dirs = new List<string>();
foreach (string item in list)
{
if (item.Contains('.'))
files.Add(item);
else
dirs.Add(item);
}

foreach (string file in files)
{
deleteFile(remoteFolder + "/" + Path.GetFileName(file));
}
foreach (string dir in dirs)
{
deleteFolderContents(remoteFolder + "/" + Path.GetFileName(dir));
deleteFolder(remoteFolder + "/" + Path.GetFileName(dir));
}

rslt = true;
}
catch (Exception)
{
rslt = false;
}

return rslt;
}
public void deleteFolder(string deleteFolder)
{
try
{
/* Create an FTP Request */
ftpRequest = (FtpWebRequest)WebRequest.Create(host + "/" + deleteFolder);
/* Log in to the FTP Server with the User Name and Password Provided */
ftpRequest.Credentials = new NetworkCredential(user, pass);
/* When in doubt, use these options */
ftpRequest.UseBinary = true;
ftpRequest.UsePassive = true;
ftpRequest.KeepAlive = true;
/* Specify the Type of FTP Request */
ftpRequest.Method = WebRequestMethods.Ftp.RemoveDirectory;
/* Establish Return Communication with the FTP Server */
ftpResponse = (FtpWebResponse)ftpRequest.GetResponse();
/* Resource Cleanup */
ftpResponse.Close();
ftpRequest = null;
}
catch (Exception ex) { Console.WriteLine(ex.ToString()); }
return;
}
