how to read file by ZipFile

download dll:

icsharpcode.sharpziplib.dll

put it into the directory unity Plugin directory.



write a path tool to get the file directory. this tool we will fill in the future.

now the code is short and not full.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System;
using System.IO;

public static class PathUtil
{
public static string ToForwardSlash(this string path)
{
return path.Replace(@"\", @"/");
}

public static string ToSingleForwardSlash(this string path)
{
return path.Replace(@"//", @"/");
}

public static string ConverRelativePathToEditorOutputPath(string relativePath)
{
string platformPath = string.Empty;
#if UNITY_ANDROID
platformPath = "Android/";
#elif UNITY_IOS
platformPath = "iOS";
#else
platformPath = "Windows";
#endif
string outputPath = Path.Combine(Application.dataPath, "../TempData/" + platformPath).ToForwardSlash().ToSingleForwardSlash();
return Path.Combine(outputPath, relativePath.ToSingleForwardSlash().ToForwardSlash()).ToForwardSlash().ToSingleForwardSlash();
}
}

last we will write a demo script the read from zip file. zip file is like this:



C# testing code is :

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.IO;
using System;
using ICSharpCode.SharpZipLib.Zip;

public class ZipFileRead : MonoBehaviour
{
private ZipFile m_zipFile;
private void OnGUI()
{
if(Input.GetKeyDown(KeyCode.A))
{
string fileName = "a.zip";
string filePath = PathUtil.ConverRelativePathToEditorOutputPath(fileName);
if(File.Exists(filePath))
{
byte[] zipBytes = File.ReadAllBytes(filePath);
m_zipFile = new ZipFile(new MemoryStream(zipBytes));
}

ZipEntry zipEntry = m_zipFile.GetEntry("a.txt");

Debug.Log(zipEntry.Name);
}
}
}

the entry in the zip can be xml. txt. and others.

will fulfill.
