移动设备可用的压缩解压缩源码

最近在做客户端数据的分离，不希望对项目有什么影响，也不太想用AssetBundle，太麻烦，就在网上找了找开源的C#压缩算法，找来找去，发现不是不支持移动端，就是不能直接压缩文件夹，总之没有一个满意的方案，最后还是找了开源的ICSharpCode.SharpZipLib.Zip的源码，调试了一下修了修，让它支持了移动端，最终解决这个问题，本着开源的精神，发到这里，希望对大家有用。

使用方法很简单，里面最外层有一个Util_Zip脚本，直接调用就行

using System;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using UnityEngine;
 
public class Util_DownloadZip : MonoBehaviour
{
        public void DownloadTo(string url, string targetDirectory, Action<string> failedDel, Action completeDel)
        {
                StartCoroutine(DownloadURL(url, targetDirectory, failedDel, completeDel));
        }
        private IEnumerator DownloadURL(string url, string targetDirectory, Action<string> failedDel, Action completeDel)
        {
                WWW www = new WWW(url);
                yield return www;
                if (www.error == null)
                {
                        try
                        {
                                Util_Zip.ExtractZip(new MemoryStream(www.bytes), targetDirectory);
                                if (completeDel != null)
                                {
                                        completeDel();
                                }
                        }
                        catch (Exception ex)
                        {
                                if (failedDel != null)
                                {
                                        failedDel("Util_Zip.ExtractZip error:" + ex.Message);
                                }
                        }
                }
                else
                {
                        if (failedDel != null)
                        {
                                failedDel(www.error + "\r\n" + url);
                        }
                }
        }
}

调用的时候第一个参数传压缩包地址，第二个参数传解压缩的文件夹，我是传的Application.persistentDataPath，这个目录安卓iOS都可读写，第三四个参数是成功和失败的回调，可空。

压缩的接口直接传两个路径进去，就不用说了吧

Enjoy~
