Question

我有这种解压缩方法，我想基于它进行压缩。谁能帮助我？（我试着自己写但不起作用）

解压缩方法：

public static byte[] Decompress(byte[] data)
{
   MemoryStream memoryStream = new MemoryStream();
   memoryStream.Write(data, 0, data.Length);
   memoryStream.Position = 0L;
   GZipStream gZipStream = new GZipStream(memoryStream, CompressionMode.Decompress, true);
   MemoryStream memoryStream2 = new MemoryStream();
   byte[] array = new byte[64];

   for (int i = gZipStream.Read(array, 0, array.Length); i > 0; i = gZipStream.Read(array, 0, array.Length))
   {
        memoryStream2.Write(array, 0, i);
   }

   gZipStream.Close();
   return memoryStream2.ToArray();
}

这就是我尝试编写Compress方法的方法，但是当我将其解压缩时没有得到正确的结果：

public static byte[] Compress(byte[] data)
        {
            MemoryStream memoryStream = new MemoryStream();
            memoryStream.Write(data, 0, data.Length);
            memoryStream.Position = 0L;
            GZipStream gZipStream = new GZipStream(memoryStream, CompressionMode.Compress, false);
            byte[] array = new byte[64];
            gZipStream.Write(array, 0, array.Length);
            gZipStream.Close();
            return memoryStream.ToArray();
        }

尝试使用以下简单实现：

public static byte[] Compress(byte[] data)
{
    using (MemoryStream memoryStream = new MemoryStream())
    using (GZipStream gzipStream = new GZipStream(memoryStream, CompressionMode.Compress, true))
    {
        gzipStream.Write(data, 0, data.Length);
        return memoryStream.ToArray();
    }
}

C＃Gzip写自定义压缩
