c#使用SharpZipLib对二进制数据进行压缩和解压

 

首先需要下载SharpZipLib，下载地址：http://icsharpcode.github.io/SharpZipLib/

需要引入命名空间：

 

using ICSharpCode.SharpZipLib.GZip;
using System.IO;

压缩：

 

public static byte[] CompressGZip(byte[] rawData)
{
    MemoryStream ms = new MemoryStream();
    GZipOutputStream compressedzipStream = new GZipOutputStream(ms);
    compressedzipStream.Write(rawData, 0, rawData.Length);
    compressedzipStream.Close();
    return ms.ToArray();
}

解压：

 

public static byte[] UnGZip(byte[] byteArray)
{
    GZipInputStream gzi = new GZipInputStream(new MemoryStream(byteArray));

    MemoryStream re = new MemoryStream(50000);
    int count;
    byte[] data = new byte[50000];
    while ((count = gzi.Read(data, 0, data.Length)) != 0)
    {
        re.Write(data, 0, count);
    }
    byte[] overarr = re.ToArray();
    return overarr;
}

测试：

 

public static void GZipTest()
    {
        string testdata = "aaaa11233GZip压缩和解压";

        byte[] gzipdata = Tools.CompressGZip(Encoding.UTF8.GetBytes(testdata));
        byte[] undata = Tools.UnGZip(gzipdata);

        Debug.Log("[GZipTest]  : data" + Encoding.UTF8.GetString(undata));
    }

结果:
