C# C中ICSharpCode…充气输入流的反向操作#

我正在使用ICSharpCode.SharpZipLib.dll压缩和解压缩数据。
我有以下执行数据膨胀的代码：

public static byte[] ZLibDecompress(byte[] zLibCompressedBuffer)
{
    byte[] resBuffer = null;

    MemoryStream mInStream = new MemoryStream(zLibCompressedBuffer);
    MemoryStream mOutStream = new MemoryStream(zLibCompressedBuffer.Length);
    InflaterInputStream infStream = new InflaterInputStream(mInStream);

    mInStream.Position = 0;

    try
    {
        byte[] tmpBuffer = new byte[zLibCompressedBuffer.Length];
        int read = 0;

        do
        {
            read = infStream.Read(tmpBuffer, 0, tmpBuffer.Length);
            if (read > 0)
                mOutStream.Write(tmpBuffer, 0, read);

        } while (read > 0);

        resBuffer = mOutStream.ToArray();
    }
    finally
    {
        infStream.Close();
        mInStream.Close();
        mOutStream.Close();
    }

    return resBuffer;
}

这段代码实际上是有效的，现在我想把结果压缩回去。
这是我的代码：

public static byte[] ZLibCompress(byte[] buffer)
{
    byte[] resBuffer = null;

    MemoryStream mOutStream = new MemoryStream(buffer.Length);
    DeflaterOutputStream defStream = new DeflaterOutputStream(mOutStream);

    try
    {
        defStream.Write(buffer, 0, buffer.Length);
        defStream.Flush();
        defStream.Finish();

        resBuffer = mOutStream.ToArray();
    }
    finally
    {
        defStream.Close();
        mOutStream.Close();
    }

    return resBuffer;
}

但两个函数的两个结果数组并不相等：

byte[] unCompBuffer = ZipUtils.ZLibDecompress(zLibBuffer);
byte[] compBuffer = ZipUtils.ZLibCompress(unCompBuffer);
bool eq = compBuffer.SequenceEqual(zLibBuffer);

eq为假。
有什么想法吗？

谢谢您的介绍。

压缩缓冲区来自哪里？它也被SharpZipLib压缩了吗？使用相同的压缩级别和选项？如果不是，您不应该期望解压缩/重新压缩的缓冲区等于原始的…

哪两个数组不相等？你是说你的压缩和解压缩结果不一样吗？详细描述问题（你可以编辑自己的答案：点击标签下的

）你还可以指定你正在使用的库吗？我像你要求的那样编辑了帖子正确-DEFLATE compression不能保证不同压缩器生成的压缩流相等。DEFLATE compression仅表示在解压缩时，解压缩的流将等于原始的未压缩流。导致压缩字节流不同的因素有字典选项、窗口大小（压缩级别）等。
