为什么我的ReceivedBufferSize很大？最多65535字节

Question

因此，我正在使用C＃中的Tcp协议，并认为可以连接到服务器。 当我连接到服务器时，它会通知我。但是然后我去检查ReceivedBufferSize就是这个receivedBuffer={byte[65536]}

实际上，它只返回几个字节。

为什么会这样？ 将其发送回客户也没有任何作用，因此我删除了该部分。 我想是因为包太大了。

这部分在这里

byte[] receivedBuffer = new byte[client.ReceiveBufferSize];

返回receivedBuffer={byte[65536]}

public partial class MainWindow : Window
{
    public static IPAddress remoteAddress = IPAddress.Parse("127.0.0.1");
    public TcpListener remoteServer = new TcpListener(remoteAddress, 7777);
    public TcpClient client = default(TcpClient);

    public MainWindow()
    {
        InitializeComponent();
    }

    private void BtnListen_OnClick(object sender, RoutedEventArgs e)
    {
        if (StartServer())
        {
            client = remoteServer.AcceptTcpClient();
            MessageBox.Show("Connected");
            byte[] receivedBuffer = new byte[client.ReceiveBufferSize];

            NetworkStream clientStream = client.GetStream();

            while (client.Connected)
            {
                if (client.Connected)
                {
                    if (client.ReceiveBufferSize > 0)
                    {
                        receivedBuffer = new byte[100];
                        clientStream.Read(receivedBuffer, 0, receivedBuffer.Length);
                    }
                }
            }
        }
    }

    private bool StartServer()
    {
        try
        {
            remoteServer.Start();
            MessageBox.Show("Server Started...");
            return true;
        }
        catch (Exception exception)
        {
            MessageBox.Show(exception.ToString());
            throw;
        }
    }
}

如您所见，它只有15个字节
