c# 压缩文件夹(包含子文件夹)

Question

压缩方法:
public void ZipFile(string strFile, string strZip)
        {
            if (strFile[strFile.Length - 1] != Path.DirectorySeparatorChar)
                strFile += Path.DirectorySeparatorChar;
            ZipOutputStream s = new ZipOutputStream(File.Create(strZip));
            s.SetLevel(9); // 0 - store only to 9 - means best compression
            zip(strFile, s, "D:\\TDDOWNLOAD\\photos");
            s.Finish();
            s.Close();
        }
        private void zip(string strFile, ZipOutputStream s, string staticFile)
        {
            if (strFile[strFile.Length - 1] != Path.DirectorySeparatorChar)
                strFile += Path.DirectorySeparatorChar;
            Crc32 crc = new Crc32();
            string[] filenames = Directory.GetFileSystemEntries(strFile);
            foreach (string file in filenames)
            {
                if (Directory.Exists(file))
                {
                    zip(file, s, staticFile);
                }                else // 否则直接压缩文件
                {
                    //打开压缩文件
                    FileStream fs = File.OpenRead(file);                    byte[] buffer = new byte[fs.Length];
                    fs.Read(buffer, 0, buffer.Length);
                    string tempfile = file.Substring(staticFile.LastIndexOf("\\") + 1);
                    ZipEntry entry = new ZipEntry(tempfile);                    entry.DateTime = DateTime.Now;
                    entry.Size = fs.Length;
                    fs.Close();
                    crc.Reset();
                    crc.Update(buffer);
                    entry.Crc = crc.Value;
                    s.PutNextEntry(entry);                    s.Write(buffer, 0, buffer.Length);
                }
            }
        }

解压方法:
 public string unZipFile(string TargetFile, string fileDir)
        {
            string rootFile = " ";
            try
            {
                //读取压缩文件(zip文件)，准备解压缩
                ZipInputStream s = new ZipInputStream(File.OpenRead(TargetFile.Trim()));
                ZipEntry theEntry;
                string path = fileDir;
                //解压出来的文件保存的路径                string rootDir = " ";
                theEntry = s.GetNextEntry();
                //根目录下的第一个子文件夹的名称
                //while ((theEntry = s.GetNextEntry()) != null)
                while ((theEntry) != null)
                {
                    rootDir = Path.GetDirectoryName(theEntry.Name);
                    //得到根目录下的第一级子文件夹的名称
                    if (rootDir.IndexOf("\\") >= 0)
                    {
                        rootDir = rootDir.Substring(0, rootDir.IndexOf("\\") + 1);
                    }
                    string dir = Path.GetDirectoryName(theEntry.Name);
                    //根目录下的第一级子文件夹的下的文件夹的名称
                    string fileName = Path.GetFileName(theEntry.Name);
                    //根目录下的文件名称
                    if (dir != " ")
                    //创建根目录下的子文件夹,不限制级别
                    {
                        if (!Directory.Exists(fileDir + "\\" + dir))
                        {
                            path = fileDir + "\\" + dir;
                            //在指定的路径创建文件夹
                            Directory.CreateDirectory(path);
                        }
                    }
                    else if (dir == " " && fileName != "")
                    //根目录下的文件
                    {
                        path = fileDir;
                        rootFile = fileName;
                    }
                    else if (dir != " " && fileName != "")
                    //根目录下的第一级子文件夹下的文件
                    {
                        if (dir.IndexOf("\\") > 0)
                        //指定文件保存的路径
                        {
                            path = fileDir + "\\" + dir;
                        }
                    }                    if (dir == rootDir)
                    //判断是不是需要保存在根目录下的文件
                    {
                        path = fileDir + "\\" + rootDir;
                    }                    //以下为解压缩zip文件的基本步骤
                    //基本思路就是遍历压缩文件里的所有文件，创建一个相同的文件。
                    if (fileName != String.Empty)
                    {
                        FileStream streamWriter = File.Create(path + "\\" + fileName);                        int size = 2048;
                        byte[] data = new byte[2048];
                        while (true)
                        {
                            size = s.Read(data, 0, data.Length);
                            if (size > 0)
                            {
                                streamWriter.Write(data, 0, size);
                            }
                            else
                            {
                                break;
                            }
                        }                        streamWriter.Close();
                    }
                }
                s.Close();                return rootFile;
            }
            catch (Exception ex)
            {
                return "1; " + ex.Message;
            }
        }

你用你下面的方法解压其他不用代码压缩的包没？
如果可以说明你的压缩方法有问题，如果不行那就是你解压有问题  FileInfo info = new FileInfo(ZipFilePath);
                using (ZipInputStream stream = new ZipInputStream(info.OpenRead()))
                {
                    if (!Directory.Exists(OutputFolder))
                    {
                        Directory.CreateDirectory(OutputFolder);
                    }
                    ZipEntry entry = null;
                    while ((entry = stream.GetNextEntry()) != null)
                    {
                        int count = 0x800;
                        byte[] buffer = new byte[0x800];
                        string[] strArray = entry.Name.Split('\\');
                        if (strArray.Length > 1)
                        {
                            StringBuilder builder = new StringBuilder(OutputFolder + info.Name);
                            int num2 = 0;
                            while (num2 < (strArray.Length - 1))
                            {
                                builder.Append(@"\");
                                builder.Append(strArray[num2++]);
                            }
                            Directory.CreateDirectory(builder.ToString());
                        }
                        string path = OutputFolder + @"\" + entry.Name;
                        if (entry.IsDirectory)
                        {
                            Directory.CreateDirectory(path);
                        }
                        else
                        {
                            if (File.Exists(path))
                            {
                                File.SetAttributes(path, FileAttributes.Normal);
                            }
                            try
                            {
                                using (FileStream stream2 = new FileStream(path, FileMode.Create))
                                {
                                Label_0107:
                                    count = stream.Read(buffer, 0, buffer.Length);
                                    if (count > 0)
                                    {
                                        stream2.Write(buffer, 0, count);
                                        goto Label_0107;
                                    }
                                    stream2.Flush();
                                    stream2.Close();
                                }
                                continue;
                            }
                            catch
                            {
                                continue;
                            }
                        }
                    }
                }
