How can i sort the directories and files order the same it is appear in my ftp server ?

[Chocolade1972]

This is how im listing the directories and files:


private int total_dirs;
private int searched_until_now_dirs;
private int max_percentage;
private TreeNode directories_real_time;

private TreeNode CreateDirectoryNode(string path, string name , int recursive_levl )
{
var directoryNode = new TreeNode(name);
var directoryListing = GetDirectoryListing(path);

var directories = directoryListing.Where(d => d.IsDirectory);
var files = directoryListing.Where(d => !d.IsDirectory);

total_dirs += directories.Count<FTPListDetail>();
searched_until_now_dirs++;

int percentage;

foreach (var dir in directories)
{
directoryNode.Nodes.Add(CreateDirectoryNode(dir.FullPath, dir.Name, recursive_levl+1));

if (recursive_levl == 1)
{
TreeNode temp_tn = (TreeNode)directoryNode.Clone();

this.BeginInvoke(new MethodInvoker( delegate
{
UpdateList(temp_tn);
}));
}

percentage = (searched_until_now_dirs * 100) / total_dirs;
if (percentage > max_percentage)
{
max_percentage = percentage;
backgroundWorker1.ReportProgress(percentage);
}
}

percentage = (searched_until_now_dirs * 100) / total_dirs;
if (percentage > max_percentage)
{
max_percentage = percentage;
backgroundWorker1.ReportProgress(percentage);
}
foreach (var file in files)
{
directoryNode.Nodes.Add(new TreeNode(file.Name));
}
return directoryNode;
}

And this is how im adding the directories to the treeview:


DateTime last_update;

private void UpdateList(TreeNode tn_rt)
{
TimeSpan ts = DateTime.Now - last_update;
if (ts.TotalMilliseconds > 200)
{
last_update = DateTime.Now;
treeView1.Nodes.Clear();
treeView1.Nodes.Add(tn_rt);
foreach (TreeNode tn in treeView1.Nodes)
{
if (tn.Level == 0)
tn.Expand();
}

}

}

It seems that in the method: CreateDirectoryNode there is some sorting but the result is that the directories in the treeview not in the same order they are in my ftp server.



And last method is how im parsing the directories and files but im not sure this is where the problem is:


public IEnumerable<FTPListDetail> GetDirectoryListing(string rootUri)
{
var CurrentRemoteDirectory = rootUri;
var result = new StringBuilder();
var request = GetWebRequest(WebRequestMethods.Ftp.ListDirectoryDetails, CurrentRemoteDirectory);
using (var response = request.GetResponse())
{
using (var reader = new StreamReader(response.GetResponseStream()))
{
string line = reader.ReadLine();
while (line != null)
{
result.Append(line);
result.Append("\n");
line = reader.ReadLine();
}
if (string.IsNullOrEmpty(result.ToString()))
{
return new List<FTPListDetail>();
}
result.Remove(result.ToString().LastIndexOf("\n"), 1);
var results = result.ToString().Split(\n);
string regex =
@"^" + //# Start of line
@"(?<dir>[\-ld])" + //# File size
@"(?<permission>[\-rwx]{9})" + //# Whitespace \n
@"\s+" + //# Whitespace \n
@"(?<filecode>\d+)" +
@"\s+" + //# Whitespace \n
@"(?<owner>\w+)" +
@"\s+" + //# Whitespace \n
@"(?<group>\w+)" +
@"\s+" + //# Whitespace \n
@"(?<size>\d+)" +
@"\s+" + //# Whitespace \n
@"(?<month>\w{3})" + //# Month (3 letters) \n
@"\s+" + //# Whitespace \n
@"(?<day>\d{1,2})" + //# Day (1 or 2 digits) \n
@"\s+" + //# Whitespace \n
@"(?<timeyear>[\d:]{4,5})" + //# Time or year \n
@"\s+" + //# Whitespace \n
@"(?<filename>(.*))" + //# Filename \n
@"$"; //# End of line

var myresult = new List<FTPListDetail>();
foreach (var parsed in results)
{
var split = new Regex(regex)
.Match(parsed);
var dir = split.Groups["dir"].ToString();
var permission = split.Groups["permission"].ToString();
var filecode = split.Groups["filecode"].ToString();
var owner = split.Groups["owner"].ToString();
var group = split.Groups["group"].ToString();
var filename = split.Groups["filename"].ToString();
myresult.Add(new FTPListDetail()
{
Dir = dir,
Filecode = filecode,
Group = group,
FullPath = CurrentRemoteDirectory + "/" + filename,
Name = filename,
Owner = owner,
Permission = permission,
});
};
return myresult;
}
}
}
