GZipStream 4G 限制 - 总计或当前流式传输？

让一个 GzipStream 提供一个 SSLStream。

今天第一次注意到 “gzip 流不能包含超过 4GB 的数据。”

at System.IO.Compression.FastEncoder.GetCompressedOutput(Byte[] outputBuffer)
at System.IO.Compression.DeflateStream.InternalWrite(Byte[] array, Int32 offset, Int32 count, Boolean isAsync)
at System.IO.Compression.DeflateStream.Write(Byte[] array, Int32 offset, Int32 count)
at System.IO.Compression.GZipStream.Write(Byte[] array, Int32 offset, Int32 count)
at ...

网络写入器输入数据的速度比读取器获取数据的速度快。因此，我不清楚错误的原因。

这是对通过流写入的总字节数的限制，还是将数据从 GZipStram 中取出并放入 SSLStream 时积压的问题？

Reader 能够在流结束之前解压缩并使用数据，因此我从未想过写入的总字节数可能有这样的限制。

似乎没有办法检查长度。

有人可以分享他们如何处理这个问题的示例吗？

代码大纲：

TcpClient network = = new TcpClient();
network.Connect(m_config.Address.Host, m_config.Address.Port);
SslStream sslStream = new SslStream(network.GetStream(), true .. ssl bits
Stream outStream = new GZipStream(sslStream, CompressionMode.Compress, true);

try {
    String nextMessage;
    while (messages.Dequeue(out nextMessage))
    {
        byte[] buffer = Encoding.UTF8.GetBytes(nextMessage + "\n");

        outStream.Write(buffer, 0, buffer.Length);
    }
} catch()

Have aa GzipStream feeding an SSLStream.

First time today noticed
"The gzip stream can't contain more than 4GB data."

The Writer to the network is feeding in data faster than the Reader is getting the data. As such the cause of the error is unclear to me.

Is this is a limitation on the total bytes written through the stream or is this is an issue with backlog getting the data out of the GZipStram and into the SSLStream?

The Reader is able to unzip and use the data before the stream ends, so I never thought that there might be such a limit on total bytes written.

There doesn't seem to be a way to check the length.

Could anybody share examples on how they handled this?

Code outline:

TcpClient network = = new TcpClient();
network.Connect(m_config.Address.Host, m_config.Address.Port);
SslStream sslStream = new SslStream(network.GetStream(), true .. ssl bits
Stream outStream = new GZipStream(sslStream, CompressionMode.Compress, true);

try {
    String nextMessage;
    while (messages.Dequeue(out nextMessage))
    {
        byte[] buffer = Encoding.UTF8.GetBytes(nextMessage + "\n");

        outStream.Write(buffer, 0, buffer.Length);
    }
} catch()
