C# 减小大型字符串数据大小的最佳方法

Question

我在谷歌上搜索了这种方法并找到了这种方法，但不确定我是否应该接受这种方法？

这是代码

    public static class StringCompression
    {
        /// <summary>
        /// Compresses a string and returns a deflate compressed, Base64 encoded string.
        /// </summary>
        /// <param name="uncompressedString">String to compress</param>
        public static string Compress(string uncompressedString)
        {
            byte[] compressedBytes;

            using (var uncompressedStream = new MemoryStream(Encoding.UTF8.GetBytes(uncompressedString)))
            {
                using (var compressedStream = new MemoryStream())
                { 
                    // setting the leaveOpen parameter to true to ensure that compressedStream will not be closed when compressorStream is disposed
                    // this allows compressorStream to close and flush its buffers to compressedStream and guarantees that compressedStream.ToArray() can be called afterward
                    // although MSDN documentation states that ToArray() can be called on a closed MemoryStream, I don't want to rely on that very odd behavior should it ever change
                    using (var compressorStream = new DeflateStream(compressedStream, CompressionLevel.Fastest, true))
                    {
                        uncompressedStream.CopyTo(compressorStream);
                    }

                    // call compressedStream.ToArray() after the enclosing DeflateStream has closed and flushed its buffer to compressedStream
                    compressedBytes = compressedStream.ToArray();
                }
            }

            return Convert.ToBase64String(compressedBytes);
        }

        /// <summary>
        /// Decompresses a deflate compressed, Base64 encoded string and returns an uncompressed string.
        /// </summary>
        /// <param name="compressedString">String to decompress.</param>
        public static string Decompress(string compressedString)
        {
            byte[] decompressedBytes;

            var compressedStream = new MemoryStream(Convert.FromBase64String(compressedString));

            using (var decompressorStream = new DeflateStream(compressedStream, CompressionMode.Decompress))
            {
                using (var decompressedStream = new MemoryStream())
                {
                    decompressorStream.CopyTo(decompressedStream);

                    decompressedBytes = decompressedStream.ToArray();
                }
            }

            return Encoding.UTF8.GetString(decompressedBytes);
        }

以这种方式调用

var uncompressedString = "Hello World!";
var compressedString = uncompressedString.Compress();

var decompressedString = compressedString.Decompress();

或者我应该使用GZipStream来压缩和解压缩字符串数据吗？

哪种方法可以最大程度地压缩大字符串数据？请指教。

Note：此问题总结整理于: C# Best Method to reduce size of large string data

Answer 1

GZipStream 类使用 gzip 数据格式，其中包括用于检测数据损坏的循环冗余校验值。gzip 数据格式使用与 DeflateStream 类相同的压缩算法。 正如 Aaronaught 所说，如果您使用 GZipStream 来压缩文件，则可以通过 WinZip 或 gzip 工具等存档器打开结果。如果使用 DeflateStream 进行压缩，则这些工具将无法识别该文件。 这是您可以参考的相关线程。 使用 C#的压缩/解压缩字符串，
