这里有新鲜出炉的精品教程，程序狗速度看过来！

.NET Framework

.NET 是 Microsoft XML Web services 平台。你可以理解为.NET Framework ,XML Web services 允许应用程序通过 Internet 进行通讯和共享数据，而不管所采用的是哪种操作系统、设备或编程语言。Microsoft .NET 平台提供创建 XML Web services 并将这些服务集成在一起之所需。对个人用户的好处是无缝的、吸引人的体验。

本篇文章小编为大家介绍，基于.NET 4.5 压缩的使用。需要的朋友参考下

在.NET 4.5中新加入的压缩的命名空间和方法。可以抛弃ICSharpCode.SharpZipLib.dll 这个类库了。性能上不相上下。但是能够大大简化你的代码。如果开始使用.NET FrameWork4.5 做压缩不妨试试自带的压缩方法.

传统使用ICSharpCode.SharpZipLib.dll 所写的代码。

static void Main(string[] args)
        {
            Stopwatch watch = new Stopwatch();
            watch.Start();
            string path = @"E:\";        
            Compress(Directory.GetFiles(path), @"F:\4.0.zip");
            watch.Stop();
            Console.WriteLine("消耗时间:{0}", watch.ElapsedMilliseconds);
            FileInfo f = new FileInfo(@"F:\4.0.zip");
            Console.WriteLine("文件大小{0}", f.Length);
        }

        static void Compress(string[] filePaths, string zipFilePath)
        {
            byte[] _buffer = new byte[4096];
            if (!Directory.Exists(zipFilePath))
                Directory.CreateDirectory(Path.GetDirectoryName(zipFilePath));
            using (ZipOutputStream zip = new ZipOutputStream(File.Create(zipFilePath)))
            {
                foreach (var item in filePaths)
                {
                    if (!File.Exists(item))
                    {
                        Console.WriteLine("the file {0} not exist!", item);
                    }
                    else
                    {
                        ZipEntry entry = new ZipEntry(Path.GetFileName(item));
                        entry.DateTime = DateTime.Now;
                        zip.PutNextEntry(entry);
                        using (FileStream fs = File.OpenRead(item))
                        {
                            int sourceBytes;
                            do
                            {
                                sourceBytes = fs.Read(_buffer, 0, _buffer.Length);
                                zip.Write(_buffer, 0, sourceBytes);
                            } while (sourceBytes > 0);
                        }
                    }
                }
                zip.Finish();
                zip.Close();
            }
        }

static void Main(string[] args)
        {
            Stopwatch watch = new Stopwatch();
            watch.Start();
            string path = @"E:\";
            Compress(path, @"F:\4.5.zip");
            watch.Stop();
            Console.WriteLine("消耗时间:{0}", watch.ElapsedMilliseconds);
            FileInfo f = new FileInfo(@"F:\4.5.zip");
            Console.WriteLine("文件大小{0}", f.Length);
        }
        static void Compress(string filePath, string zipFilePath)
        {
            ZipFile.CreateFromDirectory(filePath, zipFilePath, CompressionLevel.Fastest, false);
        }
