.NET和Android解压缩处理

1.C#代码(需要调用SharpZipLib):

using System.IO;using System.Text;using ICSharpCode.SharpZipLib.Zip.Compression.Streams;namespace ConsoleApplicationDemo{    public class ZipHelper    {        /// <summary>        /// 以Deflater方式压缩字符串，返回字节数组        /// </summary>        /// <param name="sString"></param>        /// <returns></returns>        public static byte[] ZipStr(string sString)        {            if (sString == null) return null;            byte[] bytes = Encoding.UTF8.GetBytes(sString);            return ZipByte(bytes);        }        /// <summary>        /// 以Deflater方式压缩字节数组        /// </summary>        /// <param name="bytes"></param>        /// <returns></returns>        public static byte[] ZipByte(byte[] bytes)        {            if (bytes == null)            {                return null;            }            MemoryStream ms = new MemoryStream();            using (DeflaterOutputStream zStream = new DeflaterOutputStream(ms))            {                zStream.Write(bytes, 0, bytes.Length);                zStream.Finish();                zStream.Close();            }            byte[] result = ms.ToArray();            ms.Close();            return result;        }        /// <summary>        /// 解压字节数组        /// </summary>        /// <param name="bytes"></param>        /// <returns></returns>        public static byte[] UnZip(byte[] bytes)        {            if (bytes == null)            {                return null;            }            MemoryStream ms = new MemoryStream();            using (InflaterInputStream stream = new InflaterInputStream(ms))            {                stream.Write(bytes, 0, bytes.Length);                stream.Flush();                stream.Close();            }            byte[] result = ms.ToArray();            ms.Close();            return result;        }    }}

2.Android代码:

package com.google.test;import java.io.ByteArrayOutputStream;import java.io.IOException;import java.io.UnsupportedEncodingException;import java.util.zip.*;public class ZipHelper {private final static int CacheSize = 1024;/*** * 压缩Zip *  * @param data * @return */public static byte[] zipByte(byte[] data) {Deflater compresser = new Deflater();compresser.reset();compresser.setInput(data);compresser.finish();byte result[] = new byte[0];ByteArrayOutputStream o = new ByteArrayOutputStream(1);try {byte[] buf = new byte[CacheSize];int got = 0;while (!compresser.finished()) {got = compresser.deflate(buf);o.write(buf, 0, got);}result = o.toByteArray();} catch (Exception e) {e.printStackTrace();} finally {try {o.close();} catch (IOException e) {e.printStackTrace();}compresser.end();}return result;}/*** * 压缩String *  * @param data * @return */public static byte[] zipString(String data) {byte[] input = new byte[0];try {input = data.getBytes("UTF-8");} catch (UnsupportedEncodingException e) {e.printStackTrace();return null;}byte[] result = ZipHelper.zipByte(input);return result;}/*** * 解压Zip *  * @param data * @return */public static byte[] unZipByte(byte[] data) {Inflater decompresser = new Inflater();decompresser.setInput(data);byte result[] = new byte[0];ByteArrayOutputStream o = new ByteArrayOutputStream(1);try {byte[] buf = new byte[CacheSize];int got = 0;while (!decompresser.finished()) {got = decompresser.inflate(buf);o.write(buf, 0, got);}result = o.toByteArray();} catch (Exception e) {e.printStackTrace();} finally {try {o.close();} catch (IOException e) {e.printStackTrace();}decompresser.end();}return result;}/*** * 解压Zip数据为String *  * @param data * @return */public static String unZipByteToString(byte[] data) {byte[] result = unZipByte(data);String outputString = null;try {outputString = new String(result, 0, result.length, "UTF-8");} catch (UnsupportedEncodingException e) {e.printStackTrace();}return outputString;}}
