I have this FTP Method that checks if a directory exists. It works fine at the start, but now, it's still returning true even if the directory does not exists. I tried many things, and set breakpoint to see what property of the response object I can use to determine whether the directory exists or not. I also searched the internet and the solutions don't seem to work for me. Here is my FTP method.
public bool directoryExists(string directory)
{
/* Create an FTP Request */
ftpRequest = (FtpWebRequest)FtpWebRequest.Create(host + "/" + directory);
/* Log in to the FTP Server with the User Name and Password Provided */
ftpRequest.Credentials = new NetworkCredential(user, pass);
/* Specify the Type of FTP Request */
ftpRequest.Method = WebRequestMethods.Ftp.ListDirectoryDetails;
try
{
using (ftpRequest.GetResponse())
{
return true;
}
//var response = ftpRequest.GetResponse();
//if (response != null)
// return true;
//else return false;
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
return false;
}
/* Resource Cleanup */
finally
{
ftpRequest = null;
}
}
And here is the method that calls it and returns true even if the directory does not exist:
private string getDirectory(ref FtpClass ftp, string internalID)
{
string remoteSubPathDel = internalID + "\\trunk\\prod\\xml\\delete";
string remoteSubPathUpdate = internalID + "\\trunk\\prod\\xml\\update";
string remoteSubPathNew = internalID + "\\trunk\\prod\\xml\\new";
if (ftp.directoryExists(remoteSubPathDel))
return remoteSubPathDel;
else if (ftp.directoryExists(remoteSubPathUpdate))
return remoteSubPathUpdate;
else if (ftp.directoryExists(remoteSubPathNew))
return remoteSubPathNew;
else
return String.Empty;
}
Hope someone can help. Thanks! :)
I got a work around for this problem. Not the best looking but it works.
Maybe this can help others with the same problem as mine.
public bool directoryExists2(string directory, string mainDirectory)
{
try
{
var list = this.GetFileList(mainDirectory);
if (list.Contains(directory))
return true;
else
return false;
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
return false;
}
}
EDIT: I included the GetFileList method in response to Ray Chang's comment
public string[] GetFileList(string path)
{
var ftpPath = host + "/" + path;
var ftpUser = user;
var ftpPass = pass;
var result = new StringBuilder();
try
{
var strLink = ftpPath;
var reqFtp = (FtpWebRequest)WebRequest.Create(new Uri(strLink));
reqFtp.UseBinary = true;
reqFtp.Credentials = new NetworkCredential(ftpUser, ftpPass);
reqFtp.Method = WebRequestMethods.Ftp.ListDirectory;
reqFtp.Proxy = null;
reqFtp.KeepAlive = false;
reqFtp.UsePassive = true;
using (var response = reqFtp.GetResponse())
{
using (var reader = new StreamReader(response.GetResponseStream()))
{
var line = reader.ReadLine();
while (line != null)
{
result.Append(line);
result.Append("\n");
line = reader.ReadLine();
}
result.Remove(result.ToString().LastIndexOf('\n'), 1);
}
}
return result.ToString().Split('\n');
}
catch (Exception ex)
{
Console.WriteLine("FTP ERROR: ", ex.Message);
return null;
}
finally
{
ftpRequest = null;
}
}
