C#如何实现缓冲区的数据压缩和解压

C#中可以使用System.IO.Compression命名空间来实现缓冲区的数据压缩和解压缩。以下是一个简单的示例代码：

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));     } } 

在这个示例中，我们首先定义了一个CompressData方法来压缩数据，接着定义了一个DecompressData方法来解压缩数据。最后，在Main方法中，我们可以看到如何使用这两个方法来对数据进行压缩和解压缩操作。
