复制代码 代码如下:

public static class Compressor {

public static byte[] Compress(byte[] data)

{

using (MemoryStream output = new MemoryStream())

{

using (GZipStream gzip = new GZipStream(output, CompressionMode.Compress, true))

{

gzip.Write(data, 0, data.Length);

gzip.Close();

return output.ToArray();

}

}

}

public static byte[] Decompress(byte[] data)

{

using (MemoryStream input = new MemoryStream())

{

input.Write(data, 0, data.Length);

input.Position = 0;

using (GZipStream gzip = new GZipStream(input, CompressionMode.Decompress, true))

{

using (MemoryStream output = new MemoryStream())

{

byte[] buff = new byte[64];

int read = -1;

read = gzip.Read(buff, 0, buff.Length);

while (read > 0)

{

output.Write(buff, 0, read);

read = gzip.Read(buff, 0, buff.Length);

}

gzip.Close();

return output.ToArray();

}

}

}

}
