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();
}
}
}
}
