压缩文件包含盘符问题

Question

#/// <summary>
        /// 压缩指定目录下指定文件(包括子目录下的文件)
        /// </summary>
        /// <param >args[0]为你要压缩的目录所在的路径 
        /// 例如：D:\\temp\\   (注意temp 后面加 \\ 但是你写程序的时候怎么修改都可以)</param>
        /// <param >args[1]为压缩后的文件名及其路径
        /// 例如：D:\\temp.zip</param>
        /// <param >文件过滤, 例如*.xml,这样只压缩.xml文件.</param>
        public bool ZipFileMain(string zippath, string zipfilename, string fileFilter)
        {            //string filenames = Directory.GetFiles(args[0]);            try
            {
                Crc32 crc = new Crc32();
                ZipOutputStream outStream = new ZipOutputStream(File.Create(zippath + zipfilename));                outStream.SetLevel(6); // 0 - store only to 9 - means best compression                DirectoryInfo di = new DirectoryInfo(zippath);                FileInfo[] files = di.GetFiles(fileFilter);
                cutStr = zippath.Trim();
                //压缩这个目录下的所有文件
                writeStream(ref outStream, files, crc);
                //压缩这个目录下子目录及其文件
                //direct(di, ref s, crc);                outStream.Finish();
                outStream.Close();
            }
            catch (Exception exp)
            {
                return false;            }
            Upload(zippath,zipfilename);            return true;
        }        /// <summary>
        /// 文件压缩成zip格式
        /// </summary>
        /// <param name="outStream"></param>
        /// <param name="files"></param>
        /// <param name="crc"></param>
        private void writeStream(ref ZipOutputStream outStream, FileInfo[] files, Crc32 crc)
        {
            foreach (FileInfo fi in files)
            {
                //string fifn = fi.FullName;
                FileStream fs = fi.OpenRead();                byte[] buffer = new byte[fs.Length];
                fs.Read(buffer, 0, buffer.Length);
                //ZipEntry entry = new ZipEntry(file);    Path.GetFileName(file)
                string file = fi.FullName;
                file = file.Replace(cutStr, "");                ZipEntry entry = new ZipEntry(file);                entry.DateTime = DateTime.Now;                entry.Size = fs.Length;
                fs.Close();                crc.Reset();
                crc.Update(buffer);                entry.Crc = crc.Value;                outStream.PutNextEntry(entry);                outStream.Write(buffer, 0, buffer.Length);
            }
        }
用以上方法实现压缩文件，问题是：当文件存在根盘符下面时，压缩文件中包含一个盘符文件夹（E_),打开该文件夹才能找到文件。

Answer 1

#
Upload(zippath,zipfilename);//在哪
