使用zLib1.ll指定要压缩和解压缩的文件. [英] Specify the files with zLib1.ll to compress and uncompress.

问题描述

我发现此代码调用zLib1.dll，但如何
我可以指定要压缩的文件并指定要压缩的文件名吗?
和要解压缩的情况相同吗?
C#4.0

I found this code to call the zLib1.dll but how
can I specify a file to compress and specify the file name compressed.
And the same case to uncompress?
C# 4.0

[DllImport("zlib1.dll", CallingConvention=CallingConvention.Cdecl) ] 
        static extern int compress(byte[] destBuffer, ref uint destLen, byte[] sourceBuffer, uint sourceLen);
        [DllImport("zlib1.dll", CallingConvention = CallingConvention.Cdecl)]
        static extern int uncompress(byte[] destBuffer, ref uint destLen, byte[] sourceBuffer, uint sourceLen);


public static byte[] Compress(byte[] data)
        {
            uint _dLen = (uint)((data.Length * 1.1) + 12);
            byte[] _d = new byte[_dLen];
            compress(_d, ref _dLen, data, (uint)data.Length);
            byte[] result = new byte[_dLen];
            Array.Copy(_d, 0, result, 0, result.Length);
            return result;
        }
        public static byte[] Decompress(byte[] data)
        {
            uint _dLen = 8192;
            byte[] _d = new byte[_dLen];
            if (uncompress(_d, ref _dLen, data, (uint)data.Length) != 0)
                return null;
            byte[] result = new byte[_dLen];
            Array.Copy(_d, 0, result, 0, result.Length);
            return result;
        }
