c# - 网络传输暂停

Question

我用 C# 创建了一个服务器和一个传输文件的客户端。但是在传输时它会暂停几秒钟然后继续。我已经在 YouTube 上上传了一段视频来演示:http://www.youtube.com/watch?v=GGRKRW6ihLo

如您所见，它有时会暂停然后继续。

        using (var writer = new StreamWriter(Path.Combine(_localPath, file.FileName))) {
            var buffer = new byte[_bufferSize];
            while (file.Transferred < file.Size && _active) {
                int read = ns.Read(buffer, 0, _bufferSize);
                writer.BaseStream.Write(buffer, 0, read);
                file.Transferred += read;
            }
            writer.Close();
        }

            using (var reader = new StreamReader(file.FilePath)) {
                var buffer = new byte[_bufferSize];
                while (file.Transferred < file.Size && _active) {
                    int read = reader.BaseStream.Read(buffer, 0, _bufferSize);
                    ns.Write(buffer, 0, read);
                    file.Transferred += read;
                }
                reader.Close();
            }

尝试设置

// Sends data immediately upon calling NetworkStream.Write.
tcpClient.NoDelay = true;

发送

var buffer = new byte[ tcpClient.SendBufferSize ];

阅读

var buffer = new byte[ tcpClient.ReceiveBufferSize ];

TcpClient.SendBufferSize 和 TcpClient.ReceiveBufferSize 可能因平台而异。在某些情况下，我将缓冲区大小设为 TcpClient 缓冲区大小的一半或两倍。
