多线程使用GzipStream压缩\解压缩

Question

我一次读取一个块的压缩数据，并将这些块添加到队列中。然后，当我尝试使用GzipStream解压缩该数据时，会显示InvalidDataException，表明GzipHeader中的幻数不正确。我的积木应该有什么标题？

这是我的减压代码：

    private DataBlock Decompress(DataBlock sourceBlock)
    {
        var decompressed = new byte[sourceBlock.Data.Length];

        using (MemoryStream memory = new MemoryStream(sourceBlock.Data))
        {
            using (GZipStream gzip = new GZipStream(memory, CompressionMode.Decompress))
            {
                gzip.Read(decompressed, 0, sourceBlock.Data.Length);
            }

            return new DataBlock(decompressed, sourceBlock.Id);
        }
    }

这是我的压缩代码：

    private DataBlock Compress(DataBlock sourceBlock)
    {
        using (MemoryStream memory = new MemoryStream())
        {
            using (GZipStream gzip = new GZipStream(memory, CompressionMode.Compress))
            {
                gzip.Write(sourceBlock.Data, 0, sourceBlock.Data.Length);
            }

            return new DataBlock(memory.ToArray(), sourceBlock.Id);
        }
    }

从文件中读取块：

    private void ReadDataFromFile()
    {
        if (File.Exists(this.sourceFilePath))
        {
            try
            {
                using (var fsSource = new FileStream(this.sourceFilePath, FileMode.Open, FileAccess.Read))
                {
                    while (fsSource.CanRead)
                    {
                        var buffer = new byte[this.bufferLength];

                        int n = fsSource.Read(buffer, 0, buffer.Length);

                        if (n == 0)
                        {
                            break;
                        }

                        var block = new DataBlock(buffer, this.currentReadBlockNumber++);

                        lock (this.innerDataBlockQueue)
                        {
                            innerDataBlockQueue.Enqueue(block);
                        }

                        this.newBlockDataLoaded?.Invoke(this, EventArgs.Empty);

                        SpinWait.SpinUntil(() => this.QueueIsFull(this.innerDataBlockQueue) == false);
                    }
                }
            }
            catch (Exception e)
            {
                throw e;
            }
        }
    }
