循环压缩某个目录

首先下载ICSharpCode.SharpZipLib.dll，然后添加应用

接着建类 代码如下

/// <summary>
    /// 压缩文件
    /// </summary>
    /// <param name="args">源目录 压缩成的文件</param>
    public void ZipFileMain(string[] args)
    {
        string[] filenames = Directory.GetFiles(args[0]);

        Crc32 crc = new Crc32();
        ZipOutputStream s = new ZipOutputStream(File.Create(args[1]));

        s.SetLevel(6); // 0 - store only to 9 - means best compression

       
            yasuo(args[0], args[0], false, crc, s);
       

        s.Finish();
        s.Close();
    }

    /// <summary>
    /// 循环压缩
    /// </summary>
    /// <param name="souce">源目录</param>
    /// <param name="str">文件名或目录名</param>
    /// <param name="isFile">是文件还是目录</param>
    /// <param name="crc"></param>
    /// <param name="s"></param>
    public void yasuo(string souce, string str, bool isFile, Crc32 crc, ZipOutputStream s)
    {
        if (isFile)
        {
            try
            {
                //打开压缩文件
                FileStream fs = File.OpenRead(str);

                byte[] buffer = new byte[fs.Length];
                fs.Read(buffer, 0, buffer.Length);
                //FileInfo info = new FileInfo(file);
                //压缩后显示的路径为当前压缩的目录;
                ZipEntry entry = new ZipEntry(str.Replace(souce, ""));

                //ZipEntry   entry   =   new   ZipEntry(file); //压缩后显示全路径
                entry.DateTime = DateTime.Now;

                // set Size and the crc, because the information
                // about the size and crc should be stored in the header
                // if it is not set it is automatically written in the footer.
                // (in this case size == crc == -1 in the header)
                // Some ZIP programs have problems with zip files that don't store
                // the size and crc in the header.
                entry.Size = fs.Length;
                fs.Close();

                crc.Reset();
                crc.Update(buffer);

                entry.Crc = crc.Value;

                s.PutNextEntry(entry);

                s.Write(buffer, 0, buffer.Length);
            }
            catch { }
           
        }else{
            //当前目录下的目录
            foreach (string d in Directory.GetDirectories(str))
            {
                foreach (string file in Directory.GetFiles(d))
                {
                    yasuo(souce, file, true, crc, s);

                }
                foreach (string dd in Directory.GetDirectories(d))
                {
                    yasuo(souce, dd, false, crc, s);
                }
            }
            //当前目录下的文件
            foreach (string file in Directory.GetFiles(str))
            {
                yasuo(souce, file, true, crc, s);
            }
        }
    }

 

 

具体调用如下

 string[] FileProperties = new string[2];

        FileProperties[0] = Server.MapPath("~/");//待压缩文件目录

        FileProperties[1] = Server.MapPath("~/") + "\\备份.zip";  //压缩后的目标文件

        clsZip Zc = new clsZip();

        Zc.ZipFileMain(FileProperties);

        Response.Write("<script language=javascript>alert('备份成功！')</script>");
