用的是一个插件SharpZipLib在vs的Nuget下载也可以去github下载https://github.com/icsharpcode/SharpZipLib
用这个最主要的是因为这个不用请求windows的文件读写权限关于这个权限我搞了好久到最后还不如这个好用
2、开始安装
这里介绍一下vs里的下载首先在unity中随便创建一个脚本然后双击打开进入vs在上方工具栏中选“项目-管理NuGet程序包 然后会出现一个界面 点击上方的浏览-在搜索框中直接搜索SharpZipLib然后会出现一堆的东西不要犹豫就是第一个应该是吧点击安装 安装好后进入unity你会发现我们安装的.dll并不在unity工程中那是因为vs给我们下载到了Packages中我们进入Packages找插件名称的文件夹进去后选lib文件夹然后根据自己用的API版本拖不同的SharpZipLib.dll进unity中拿我的举例我的是.net2.1,那我就拿net2.1进去 至此引用完成
3、简单使用
我们在unity中创建zip.cs脚本
using ICSharpCode.SharpZipLib.Checksum;
using ICSharpCode.SharpZipLib.Zip;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;namespace VRS.Util
{public class Zip{/// summary/// 压缩文件夹/// /summary/// param namedirPath压缩文件夹的路径/param/// param namefileName生成的zip文件路径/param/// param namelevel压缩级别 0 - 9 0是存储级别 9是最大压缩/param/// param namebufferSize读取文件的缓冲区大小/parampublic void CompressDirectory(string dirPath, string fileName, int level, int bufferSize){byte[] buffer new byte[bufferSize];using (ZipOutputStream s new ZipOutputStream(File.Create(fileName))){s.SetLevel(level);CompressDirectory(dirPath, dirPath, s, buffer);s.Finish();s.Close();}}/// summary/// 压缩目录/// /summary/// param nameFolderToZip待压缩的文件夹全路径格式/param/// param nameZipedFile压缩后的文件名全路径格式/param/// returns/returnspublic bool ZipFileDictory(string FolderToZip, string ZipedFile, string Password ){bool res;if (!Directory.Exists(FolderToZip))return false;ZipOutputStream s new ZipOutputStream(File.Create(ZipedFile));s.SetLevel(6);if (!string.IsNullOrEmpty(Password.Trim()))s.Password Password.Trim();res ZipFileDictory(FolderToZip, s, );s.Finish();s.Close();return res;}/// summary/// 递归压缩文件夹方法/// /summary/// param nameFolderToZip/param/// param names/param/// param nameParentFolderName/paramprivate bool ZipFileDictory(string FolderToZip, ZipOutputStream s, string ParentFolderName){bool res true;string[] folders, filenames;ZipEntry entry null;FileStream fs null;Crc32 crc new Crc32();try{//创建当前文件夹entry new ZipEntry(Path.Combine(ParentFolderName, Path.GetFileName(FolderToZip) /)); //加上 “/” 才会当成是文件夹创建s.PutNextEntry(entry);s.Flush();//先压缩文件再递归压缩文件夹filenames Directory.GetFiles(FolderToZip);foreach (string file in filenames){//打开压缩文件fs File.OpenRead(file);byte[] buffer new byte[fs.Length];fs.Read(buffer, 0, buffer.Length);entry new ZipEntry(Path.Combine(ParentFolderName, Path.GetFileName(FolderToZip) / Path.GetFileName(file)));entry.DateTime DateTime.Now;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{res false;}finally{if (fs ! null){fs.Close();fs null;}if (entry ! null)entry null;GC.Collect();GC.Collect(1);}folders Directory.GetDirectories(FolderToZip);foreach (string folder in folders){if (!ZipFileDictory(folder, s, Path.Combine(ParentFolderName, Path.GetFileName(FolderToZip))))return false;}return res;}/// summary/// 压缩文件夹/// /summary/// param nameroot压缩文件夹路径/param/// param namepath压缩文件夹内当前要压缩的文件夹路径/param/// param names/param/// param namebuffer读取文件的缓冲区大小/paramprivate void CompressDirectory(string root, string path, ZipOutputStream s, byte[] buffer){//root root.TrimEnd(//) //;string[] fileNames Directory.GetFiles(path);string[] dirNames Directory.GetDirectories(path);string relativePath path.Replace(root, );if (relativePath ! ){relativePath relativePath.Replace(//, /) /;}int sourceBytes;foreach (string file in fileNames){ZipEntry entry new ZipEntry(relativePath Path.GetFileName(file));entry.DateTime DateTime.Now;s.PutNextEntry(entry);using (FileStream fs File.OpenRead(file)){do{sourceBytes fs.Read(buffer, 0, buffer.Length);s.Write(buffer, 0, sourceBytes);} while (sourceBytes 0);}}foreach (string dirName in dirNames){string relativeDirPath dirName.Replace(root, );ZipEntry entry new ZipEntry(relativeDirPath.Replace(//, /) /);s.PutNextEntry(entry);CompressDirectory(root, dirName, s, buffer);}}/// summary/// 解压缩zip文件/// /summary/// param namezipFilePath解压的zip文件路径/param/// param nameextractPath解压到的文件夹路径/param/// param namebufferSize读取文件的缓冲区大小/parampublic void Extract(string zipFilePath, string extractPath, int bufferSize){//extractPath extractPath.TrimEnd(//) //;byte[] data new byte[bufferSize];int size;using (ZipInputStream s new ZipInputStream(File.OpenRead(zipFilePath))){ZipEntry entry;while ((entry s.GetNextEntry()) ! null){string directoryName Path.GetDirectoryName(entry.Name);string fileName Path.GetFileName(entry.Name);//先创建目录if (directoryName.Length 0){Directory.CreateDirectory(extractPath directoryName);}if (fileName ! String.Empty){using (FileStream streamWriter File.Create(extractPath entry.Name.Replace(/, //))){while (true){size s.Read(data, 0, data.Length);if (size 0){streamWriter.Write(data, 0, size);}else{break;}}}}}}}public 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(6); // 压缩级别 0-9CreateZipFiles(sourceFilePath, zipStream, sourceFilePath);zipStream.Finish();zipStream.Close();}/// summary/// 递归压缩文件/// /summary/// param namesourceFilePath待压缩的文件或文件夹路径/param/// param namezipStream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 namestaticFile/paramprivate static void CreateZipFiles(string sourceFilePath, ZipOutputStream zipStream, string staticFile){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, staticFile);}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(staticFile.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);}}}}
}
然后我们随便创建一个脚本测试
public class Test_ZipWrapper : MonoBehaviour
{// Start is called before the first frame updatevoid Start(){Zip zip new Zip();//zip.CompressDirectory(, D:/PowerModel/新建文件夹, 5,2048);zip.ZipFileDictory(D:/PowerModel/新建文件夹, D:/PowerModel/新建文件夹.zip);//zip.Extract(D:/PowerModel/新建文件夹.zip, D:/PowerModel/,2048);}}
在这里我们主要调用的是ZipFileDictory方法两个固定参数和一个可选参数一个是要打压缩包的路径一个是压缩包保存的路径可选参数就是压缩包是否要上密码该代码随便挂一个物体上运行可以看到我们成功了 解压的话是用Extract还是三个参数要解压的压缩包路径、解压后的路径、和缓冲区这个缓冲区和我们的TCP读流的缓冲区差不多随便填我这里填的是2048你可以填别的数字运行后我们成功了 大家快去试试吧
