C# 在将 GZipStream 复制到 MemoryStream 时无法访问已关闭的流

Question

我一直在尝试将 GZipStream 转换为 MemoryStream，然后将其转换为字节数组，而无需将任何文件写入硬盘。我一直在尝试将其复制到 MemoryStream，但出现此错误：未处理的异常：System.ObjectDisposedException：无法访问已关闭的流。

我已经查看了其他一些解决方案，但我无法将它们成功实施到我想要完成的目标中。

GZipStream decompressedStream = Decompress(new FileInfo(args[0]));
        using (var finalStream = new MemoryStream())
        {
            decompressedStream.CopyTo(finalStream);
            byte[] decompressedBytes = new byte[finalStream.Length];
        }

编辑：有人想让我添加 Decompress() 的代码，所以这里是

public static GZipStream Decompress(FileInfo fileToDecompress)
    {
        using (FileStream originalFileStream = fileToDecompress.OpenRead())
        {
            string currentFileName = fileToDecompress.FullName;
            string newFileName = currentFileName.Remove(currentFileName.Length - fileToDecompress.Extension.Length) + " (decompressed)";
            using (FileStream decompressedFileStream = File.Create(newFileName))
            {
                using (GZipStream decompressionStream = new GZipStream(originalFileStream, CompressionMode.Decompress))
                {
                    return decompressionStream;
                }
            }
        }
    }

问题在这里：

using (GZipStream decompressionStream = new GZipStream(originalFileStream, CompressionMode.Decompress))
{
     return decompressionStream;
}

using 语句（参见 this 文章）处理流，您不能在块外使用它。将您的 MemoryStream 处理移到此块中，并从该方法中移动 return byte[]。

像这样的东西应该可以工作：

public static byte[] Decompress(FileInfo fileToDecompress)
{
    using (FileStream originalFileStream = fileToDecompress.OpenRead())
    {
        string currentFileName = fileToDecompress.FullName;
        string newFileName = currentFileName.Remove(currentFileName.Length - fileToDecompress.Extension.Length) + " (decompressed)";
        using (FileStream decompressedFileStream = File.Create(newFileName))
        {
            using (GZipStream decompressionStream = new GZipStream(originalFileStream, CompressionMode.Decompress))
            using (var finalStream = new MemoryStream())
            {
                decompressionStream.CopyTo(finalStream);
                return finalStream.ToArray();
            }
        }
    }
}
