Bug when using the java.util.zip classes to write zip files

using ICSharpCode.SharpZipLib.Zip;

/// 

/// Packs a folder and all files in all its subfolders into a ZIP file preserving the relative paths
/// Requires ICSharpCode.SharpZipLib library

{
	ZipOutputStream i_zStream = new ZipOutputStream(File.Create(s_ZipFile));
	i_zStream.SetLevel(5); // Compression level (0-9)

	int s32_BaseFolderLen = s_Folder.Length;
	if (s_Folder.Substring(s_Folder.Length-1) != "\\") s32_BaseFolderLen ++;

	ArrayList i_FileList = new ArrayList();
	EnumFiles(ref i_FileList, s_Folder, "*.*", true);

	Byte[] u8_Buf = new Byte[0x100000]; // 1 Megabyte buffer

	foreach (string s_File in i_FileList)
	{
		FileStream i_fStream = null;
		// Catch errors of files which are locked (cannot be opened)
		try   { i_fStream = File.OpenRead(s_File); }
		catch { continue; }

		// Cut the base folder ("E:\ZipFolder\Subfolder\File.txt" -> "Subfolder/File.txt")
		// The zip archive requires "/" as separator
		string s_ZipPath = s_File.Substring(s32_BaseFolderLen).Replace("\\", "/");

		ZipEntry i_ZipEntr = new ZipEntry(s_ZipPath);
		FileInfo i_Info    = new FileInfo(s_File);
		i_ZipEntr.DateTime = i_Info.LastWriteTime;
		i_zStream.PutNextEntry(i_ZipEntr);

		while (true)
		{
			int s32_Len = i_fStream.Read(u8_Buf, 0, u8_Buf.Length);
			if (s32_Len <= 0)
				break;
			
			i_zStream.Write(u8_Buf, 0, s32_Len);
		}

		i_fStream.Close();
	}

	i_zStream.Finish();
	i_zStream.Close();

Request - Could everyone who have in the past, posted on my personal forum on CP, be kind enough to delete all your posts please? I intend to start a personal non-technical blog there, now that it is RSSd and would very much like to empty the forum before I do so - because the posts that are there as of now are mostly test posts and posts that were made before we all knew it was a blog
