这段deflate解压缩代码有何问题，为什么不能读出数据

[最后一只恐龙]

把字节数组_byCompressed解压缩，Read时返回值为0

        private void btnDecompress_Click(object sender, EventArgs e)
        {
            // 内存数据流
            MemoryStream memStream = new MemoryStream(_byCompressed);
            memStream.Position = 0;

            // 解压缩数据流
            byte[] byBuffer = new byte[1024];
            DeflateStream deflateStream = new DeflateStream(memStream, CompressionMode.Decompress, true);
            int nLen = deflateStream.Read(byBuffer, 0, 1024);// 读完nLen=0
            
            // 关闭数据流
            deflateStream.Close();
            memStream.Close();

            // 显示还原后的数据，这个函数就不用管了
            ShowBytes(tbDecompressed, byBuffer, nLen);
        }

问题是以下这句

int nLen = deflateStream.Read(byBuffer, 0, 1024);// 读完nLen=0

返回值总是0，也就是没有读出数据，为什么啊。_byCompressed的长度不是0，我实验中是132。

没用过，友情UP

MemoryStream ms = new MemoryStream();
DeflateStream compressedzipStream = new DeflateStream(ms , CompressionMode.Compress, true);
compressedzipStream.Write(buffer, 0, buffer.Length);
compressedzipStream.Close();
ms.Position = 0;
DeflateStream zipStream = new DeflateStream(ms, CompressionMode.Decompress);
byte[] decompressedBuffer = new byte[buffer.Length + 100];
int totalCount = DeflateTest.ReadAllBytesFromStream(zipStream, decompressedBuffer);

[Quote=引用 3 楼 wuyq11 的回复:]
MemoryStream ms = new MemoryStream();
DeflateStream compressedzipStream = new DeflateStream(ms , CompressionMode.Compress, true);
compressedzipStream.Write(buffer, 0, buffer.Length);
compressed……

DeflateTest.ReadAllBytesFromStream(zipStream, decompressedBuffer);是怎么实现的？我用zipStream.Read(decompressedBuffer, 0, nLen);还是不行。

再就是你在compressedzipStream.Write(buffer, 0, buffer.Length);的时候，不是把要解压缩的数据又压缩了一遍吗？

可以读出数据，但还是原来的数据，因为压缩了一次，又解压缩了一次
