如何在没有流或系统 io 的情况下压缩字节数组

我正在尝试将图像编码为字节数组并将其发送到服务器。 编码和发送部分工作正常，但我的问题是字节数​​组太大并且发送时间太长，所以我认为压缩它会让它运行得更快。但实际的问题是我不能使用 system.io 或流。我的目标是.net 2.0。 谢谢。

using System.IO;
using System.IO.Compression;

code:

public static byte[] Compress(byte[] data)
{
    MemoryStream output = new MemoryStream();
    using (DeflateStream dstream = new DeflateStream(output, CompressionLevel.Optimal))
    {
        dstream.Write(data, 0, data.Length);
    }
    return output.ToArray();
}

public static byte[] Decompress(byte[] data)
{
    MemoryStream input = new MemoryStream(data);
    MemoryStream output = new MemoryStream();
    using (DeflateStream dstream = new DeflateStream(input, CompressionMode.Decompress))
    {
        dstream.CopyTo(output);
    }
    return output.ToArray();
}

使用 7zip 库：

// Convert the text into bytes
byte[] DataBytes = ASCIIEncoding.ASCII.GetBytes(OriginalText);

// Compress it
byte[] Compressed = SevenZip.Compression.LZMA.SevenZipHelper.Compress(DataBytes);

// Decompress it
byte[] Decompressed = SevenZip.Compression.LZMA.SevenZipHelper.Decompress(Compressed);
