Question

我尝试编写一个Java服务器套接字和一个客户端写入C＃发送和接收来自服务器的数据。我想压缩gzip数据：

Java Socket Server：

GZIPInputStream zip = new server.getInputStream());

while (true) {
    int c;
    c = zip.read();
    if (c == -1)
        break;
    System.out.print((char) c);
}

String resp = "hello";
byte[] dataToCompress = resp.getBytes();
ByteArrayOutputStream byteStream = new ByteArrayOutputStream(dataToCompress.length);
GZIPOutputStream  zipStream = new GZIPOutputStream(byteStream);
    zipStream.write(dataToCompress);

    byte[] compressedData = byteStream.toByteArray();

server.getOutputStream().write(compressedData);

C＃套接字客户端：

TcpClient client = new TcpClient();

// 1. connect
client.Connect("127.0.0.1", PORT_NUMBER);
Stream stream = client.GetStream();
string str = "hello";
// 2. send

byte[] input = Encoding.UTF8.GetBytes(str);
byte[] data = new byte[BUFFER_SIZE];
//data = Compress(input);
data =  Zip(input);
//data = input;
stream.Write(data, 0, data.Length);

// 3. receive
data = new byte[BUFFER_SIZE];

stream.Read(data, 0, BUFFER_SIZE);
string ss = UnZip(data);
Console.WriteLine(ss);

    public static byte[] Zip(byte[] byteArray)
    {
        System.IO.MemoryStream ms = new System.IO.MemoryStream();
        System.IO.Compression.GZipStream sw = new System.IO.Compression.GZipStream(ms,
            System.IO.Compression.CompressionMode.Compress);

        //Compress
        sw.Write(byteArray, 0, byteArray.Length);
        //Close, DO NOT FLUSH cause bytes will go missing...
        sw.Close();

        //Transform byte[] zip data to string
        byteArray = ms.ToArray();
        return byteArray;
    }

    public static string UnZip(byte[] byteArray)
    {
        System.IO.MemoryStream ms = new System.IO.MemoryStream(byteArray);
        System.IO.Compression.GZipStream sr = new System.IO.Compression.GZipStream(ms,
            System.IO.Compression.CompressionMode.Decompress);

        //Reset variable to collect uncompressed result
        byteArray = new byte[byteArray.Length];

        //Decompress
        int rByte = sr.Read(byteArray, 0, byteArray.Length);

        //Transform byte[] unzip data to string
        System.Text.StringBuilder sB = new System.Text.StringBuilder(rByte);
        //Read the number of bytes GZipStream red and do not a for each bytes in
        //resultByteArray;
        for (int i = 0; i < rByte; i++)
        {
            sB.Append((char)byteArray[i]);
        }
        sr.Close();
        ms.Close();
        sr.Dispose();
        ms.Dispose();
        return sB.ToString();
    }

但它出错了。当我将数据从C＃发送到java时，它正确地进行压缩和解压缩，但是当我将数据从Java发送到C＃时，它会产生异常并且我将字节数组数据压缩为C＃并将字节数组压缩为Java，这是不同的。

我的代码是如何正确工作的？

Java压缩gzip字符串不正确
