I need some help here guys,
I need to represent Set in the following form
[L,R]
where L is the left hand-bound of the set , and R is the right hand-bound
each of L and R are a collection of sets
for example
L= [{1},{2},{2,3}]
R=[{1,2,3},{2,3,4}]
[L,R]= [{ {1},{2},{2,3} } , { {1,2,3},{2,3,4} }]
how can i do that in an efficient way that allows me to manipulate the set (calculate subsets and super sets from L and R..etc)? (i.e, checks weather elements in L are subsets of some elements in R?

There's no set class in .NET. AFAIK you need to write this all yourself.
Your set is a list of lists ?

Yes, but it's not very usable for normal set operations; mine's better.

Why? I see all the normal set methods there.

Not as operators, you can't string a bunch of them together to form an expression.
My guess is that it was primarily written for internal use by Linq, not for actual use by developers.
And as was pointed out with my Set class, it works better as a struct.

I suggest my Set[^] class (or struct).

I wrote an article on how to use google, just because so many people ask here how to send an email, and it's a subject so easily answered by searching this site, or googling the web.

post the error you are getting
And why don't you want to do it the standard way of using IComparer?

You posted the same question yesterday
1) Why don't you want to use an IComparer? There is nothing wrong with it and it's the standard way to do sorting.
2) Post the error message you are getting.
Perhaps then someone will answer you.

FtpWebRequest reqFTP;
dirName = "/dir1//dir2//dir3";
reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + ip + "/" + dirName));
reqFTP.Method = WebRequestMethods.Ftp.MakeDirectory;
this.textBox_status.Text += WebRequestMethods.Ftp.ListDirectory;
reqFTP.UseBinary = true;
reqFTP.Credentials = new NetworkCredential(Username, Password);
FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();
Stream ftpStream = response.GetResponseStream();
ftpStream.Close();
response.Close();
First, how to check the folder exist or not on the FTP?
The code can only create a directory in the path can we create multiple directory in the same time?
Thanks
