        {            

            //创建压缩文件包

            {
                FileStream fs = File.OpenRead(savePath  + file);
                byte[] buffer = new byte[fs.Length];
                fs.Read(buffer, 0, buffer.Length);
                ZipEntry entry = new ZipEntry(file);
                s.PutNextEntry(entry);
                s.Write(buffer, 0, buffer.Length);
                fs.Close();
            }
            s.Finish();
            s.Close();
        }
        catch (Exception ex)
        {
            Utils.throwErrorBack(@"压缩文件(ZIP)时出错,访问路径:" + savePath + "," + ex.Message);
        }
        return zipName;
    }

 

                注:此压缩方法需要引进一个DLL文件,这个文件可以去网上下载.
