我測試了下壓縮byte[]，是可以的

using System;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using System.IO.Compression;
using UnityEngine;

public class TestByteAttay : MonoBehaviour {

    // Use this for initialization
 

    void Start () {
        //測試字符串
        string inputStr = "[email protected],[email protected],[email protected]";
        print("原文:\t" + inputStr);

        byte[] input = System.Text.Encoding.Default.GetBytes(inputStr);
        print("長度:\t" + input.Length);

        byte[] data = gzipCompress(input);
        print(
 
"壓縮後:\t");
        print("長度:\t" + data.Length);
    }
    
    // Update is called once per frame
    void Update () {
        
    }

    void YaSuo()
    {
        
    }
    
    //gzip字節數組壓縮  
    public static byte[] gzipCompress(byte[] data)
    {
        try
        {
            MemoryStream ms 
 
= new MemoryStream();
            GZipStream zip = new GZipStream(ms, CompressionMode.Compress, true);
            zip.Write(data, 0, data.Length);
            zip.Close();
            byte[] buffer = new byte[ms.Length];
            ms.Position = 0;
            ms.Read(buffer, 0, buffer.Length);
            ms.Close();
            return buffer;

        }
        catch (Exception e)
        {
            throw new Exception(e.Message);
        }
    }

    
    //gzip字節數組解壓縮  
    public static byte[] gzipDecompress(byte[] data)
    {
        try
        {
            MemoryStream ms = new MemoryStream(data);
            GZipStream zip = new GZipStream(ms, CompressionMode.Decompress, true);
            MemoryStream msreader = new MemoryStream();
            byte[] buffer = new byte[0x1000];
            while (true)
            {
                int reader = zip.Read(buffer, 0, buffer.Length);
                if (reader <= 0)
                {
                    break;
                }
                msreader.Write(buffer, 0, reader);
            }
            zip.Close();
            ms.Close();
            msreader.Position = 0;
            buffer = msreader.ToArray();
            msreader.Close();
            return buffer;
        }
        catch (Exception e)
        {
            throw new Exception(e.Message);
        }
    }
}

c#實現gzip壓縮解壓縮算法：byte[]字節數組，文件，字符串，數據流的壓縮解壓縮
