Problems creating a Tar Archive with SharpZipLib

[Flix]

The following piece of code should turn the folder IN and its subfolders
into a single tar file
located in the folder OUT:

using ICSharpCode.Sha rpZipLib;
using ICSharpCode.Sha rpZipLib.Tar;

public static void Create_Tar_Arch ive(string IN,string OUT)
{
//IN and OUT are directories
if (IN=="" || OUT=="" || !System.IO.Dire ctory.Exists(IN )
|| !System.IO.Dire ctory.Exists(OU T)) return;
string OutName=OUT+"\\ "+System.IO.Pat h.GetFileName(I N)+".tar";

Stream stmout=new FileStream(OutN ame,FileMode.Op enOrCreate);
TarArchive
TA=ICSharpCode. SharpZipLib.Tar .TarArchive.Cre ateOutputTarArc hive(stmout);
TarEntry TE=TarEntry.Cre ateEntryFromFil e(IN);
TA.WriteEntry(T E,true);
TA.CloseArchive ();
stmout.Close();
}

The code seems to work but inside the output tar archive the file paths are
absolute and not relative (they start with C:\...),
and so any attemp to "decompress " the archive into a target folder fails
(illegal paths).

I would like to know how to create a tar archive with relative file paths,
i.e. with a root directory named like System.IO.Path. GetFileName(IN) and the
relative subfolders inside it,
or simply with the files and subfolders of the directory IN in first place
with relative paths.

I don't know how to create the TarEntries to achieve that (the documentation
is not so clear).

Code or links are welcome. Thank you in advance.

I would like to know how to create a tar archive with relative file paths,
i.e. with a root directory named like System.IO.Path. GetFileName(IN) and the relative subfolders inside it,

I've solved it changing the current directory with
System.IO.Direc tory.SetCurrent Directory(new_p ath) before any operation, and
providing the function with a relative path directory.
