打包需要用到第三方的dll==》ICSharpCode.SharpZipLib.dll，可以到官网去下载http://icsharpcode.github.io/SharpZipLib/

下载之后解压，把包含ICSharpCode.SharpZipLib.dll的bin文件夹拖到unity中去。

之后就是代码的编写了：

using UnityEngine;using System.Collections;using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.IO;using ICSharpCode.SharpZipLib;using ICSharpCode.SharpZipLib.Zip;using ICSharpCode.SharpZipLib.Checksums;using ICSharpCode.SharpZipLib.Core;public class ZipHelper : MonoBehaviour{    void Start()    {               CreateZip(Application.dataPath+"/Image",Application.dataPath+"/NewImage.zip");    }    /// <summary>    /// 压缩文件    /// </summary>    /// <param name="sourceFilePath"></param>    /// <param name="destinationZipFilePath"></param>    public static void CreateZip(string sourceFilePath, string destinationZipFilePath)    {        if (sourceFilePath[sourceFilePath.Length - 1] != System.IO.Path.DirectorySeparatorChar)            sourceFilePath += System.IO.Path.DirectorySeparatorChar;        ZipOutputStream zipStream = new ZipOutputStream(File.Create(destinationZipFilePath));        zipStream.SetLevel(9);  // 压缩级别 0-9        CreateZipFiles(sourceFilePath, zipStream);        zipStream.Finish();        zipStream.Close();    }    /// <summary>    /// 递归压缩文件    /// </summary>    /// <param name="sourceFilePath">待压缩的文件或文件夹路径</param>    /// <param name="zipStream">打包结果的zip文件路径（类似 D:\WorkSpace\a.zip）,全路径包括文件名和.zip扩展名</param>    /// <param name="staticFile"></param>    private static void CreateZipFiles(string sourceFilePath, ZipOutputStream zipStream)    {        Crc32 crc = new Crc32();        string[] filesArray = Directory.GetFileSystemEntries(sourceFilePath);        foreach (string file in filesArray)        {            if (Directory.Exists(file))                     //如果当前是文件夹，递归            {                CreateZipFiles(file, zipStream);            }            else                                            //如果是文件，开始压缩            {                FileStream fileStream = File.OpenRead(file);                byte[] buffer = new byte[fileStream.Length];                fileStream.Read(buffer, 0, buffer.Length);                string tempFile = file.Substring(sourceFilePath.LastIndexOf("\\") + 1);                ZipEntry entry = new ZipEntry(tempFile);                entry.DateTime = DateTime.Now;                entry.Size = fileStream.Length;                fileStream.Close();                crc.Reset();                crc.Update(buffer);                entry.Crc = crc.Value;                zipStream.PutNextEntry(entry);                zipStream.Write(buffer, 0, buffer.Length);            }        }    }}

解压完要是在unity中看不到，刷新一遍就好了。
