C#如何實(shí)現(xiàn)緩沖區(qū)的數(shù)據(jù)壓縮和解壓

C#中可以使用System.IO.Compression命名空間來(lái)實(shí)現(xiàn)緩沖區(qū)的數(shù)據(jù)壓縮和解壓縮。以下是一個(gè)簡(jiǎn)單的示例代碼：

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

public class CompressionExample
{
    public static byte[] CompressData(byte[] data)
    {
        using (MemoryStream compressedStream = new MemoryStream())
        {
            using (DeflateStream compressionStream = new DeflateStream(compressedStream, CompressionMode.Compress))
            {
                compressionStream.Write(data, 0, data.Length);
            }
            return compressedStream.ToArray();
        }
    }

    public static byte[] DecompressData(byte[] data)
    {
        using (MemoryStream compressedStream = new MemoryStream(data))
        {
            using (MemoryStream decompressedStream = new MemoryStream())
            {
                using (DeflateStream decompressionStream = new DeflateStream(compressedStream, CompressionMode.Decompress))
                {
                    decompressionStream.CopyTo(decompressedStream);
                }
                return decompressedStream.ToArray();
            }
        }
    }

    public static void Main(string[] args)
    {
        byte[] originalData = new byte[] { 1, 2, 3, 4, 5 };
        byte[] compressedData = CompressData(originalData);
        byte[] decompressedData = DecompressData(compressedData);

        Console.WriteLine("Original Data: " + BitConverter.ToString(originalData));
        Console.WriteLine("Compressed Data: " + BitConverter.ToString(compressedData));
        Console.WriteLine("Decompressed Data: " + BitConverter.ToString(decompressedData));
    }
}

在這個(gè)示例中，我們首先定義了一個(gè)CompressData方法來(lái)壓縮數(shù)據(jù)，接著定義了一個(gè)DecompressData方法來(lái)解壓縮數(shù)據(jù)。最后，在Main方法中，我們可以看到如何使用這兩個(gè)方法來(lái)對(duì)數(shù)據(jù)進(jìn)行壓縮和解壓縮操作。
