问C# GZipStream在通过MemoryStream解压缩时不能使用CopyTo方法

EN

// code href="https://www.cnblogs.com/mahuanpeng/p/6851793.html" 
// Compress bytes
//1. Create a compressed data stream
//2. Set compressStream to store the compressed file stream and set it to compression mode
//3. Write the bytes to be compressed to the compressed file stream
public static byte[] CompressBytes(byte[] bytes)
{
  Using (MemoryStream by compressStream = new MemoryStream())
  {
     Using (var zipStream = new GZipStream(compressStream, System.IO.Compression.CompressionLevel.SmallestSize))
     ZipStream.Write(bytes,0, bytes.Length).
     Return compressStream.ToArray();
  }
}


// Unzip the bytes
//1. Create a compressed data stream
//2. Create the GzipStream object and pass in the unzipped file stream
//3. Create the target flow
//4. Copy zipStream to the destination stream
//5. Return destination stream output bytes
public static byte[] Decompress(byte[] bytes)
