如何使用TcpListener读取大数据

Question

我想在套接字编程中使用TcpListener读取大于1024字节的数据。当我尝试从网络流中读取数据时，它会分成多个部分。

const int port = 1200;
this._ip = IPAddress.Parse("192.168.0.12");
this._server = new TcpListener(this._ip, port);
this._server.Start();
while (true)
{
    var client = this._server.AcceptTcpClient();
    var remoteEndPoint = (IPEndPoint)client.Client.RemoteEndPoint;
    Console.WriteLine(@"Connected");
    this._publicIp = "";
    if (remoteEndPoint != null)
    {
        this._publicIp = remoteEndPoint.Address.ToString();
    }
    this._stream = client.GetStream();
    int i = _stream.Read(_bytes, 0, _bytes.Length);                          
    string str = Encoding.ASCII.GetString(_bytes, 0, i);
    client.Close();
}
int i = _stream.Read(_bytes, 0, _bytes.Length);
string str = Encoding.ASCII.GetString(_bytes, 0, i);

尝试一下，这与使用SendReceiveBuffer有关

TcpListener tcpListener = new TcpListener(IPAddress.Any, serverTCPPort);
                tcpListener.Start();
                string received = "";
                while (true)
                {
                    tcpClient = tcpListener.AcceptTcpClient();

                    stream = tcpClient.GetStream();
                    reader = new StreamReader(stream);
                    writer = new StreamWriter(stream);
                    writer.NewLine = "\r\n";
                    writer.AutoFlush = true;
                    byte[] bytes = new byte[tcpClient.SendBufferSize];
                    int recv = 0;
                    while (true)
                    {
                        recv = stream.Read(bytes, 0, tcpClient.SendBufferSize);
                        received += System.Text.Encoding.ASCII.GetString(bytes, 0, recv);

                        if (received.EndsWith("\n\n"))
                        {
                            break;
                        }
                    }
}
