TcpClient.Receive -截断数据

Question

private static Socket ConnectSocket(string server, int port)
{
    Socket s = null;
    IPHostEntry hostEntry = null;

    hostEntry = Dns.GetHostEntry(server);

    foreach (IPAddress address in hostEntry.AddressList)
    {
        IPEndPoint ipe = new IPEndPoint(address, port);
        Socket tempSocket =
            new Socket(ipe.AddressFamily, SocketType.Stream, ProtocolType.Tcp);

        tempSocket.Connect(ipe);

        if (tempSocket.Connected)
        {
            s = tempSocket;
            break;
        }
        else
        {
            continue;
        }
    }
    return s;
}

//...

Socket s = ConnectSocket(server, port);

//...

do
{
    bytes = s.Receive(bytesReceived, bytesReceived.Length, 0); // 1
    page = page + Encoding.UTF8.GetString(bytesReceived, 0, bytes); // 2
}
while (bytes == 1024);

这是一个“页”割礼(无结束)的数据。如果在"/ / 1“和"/ / 2”之间写入System.Threading.Thread.Sleep(100)，那么一切都正常。

我看不出那是怎么回事。没有只有三个参数的接收重载。另外，您将bytesReceived.Length放在了一个不正确的位置。

s.Receive(bytesReceived, 0, bytesReceived.Length);

编辑：噢。您正在为SocketFlags使用零。别用神奇的数字。

然后没有任何信息表明每次必须到达1024字节，TCP不是这样构建的。TCP只保证所有字节都会到达，而不是何时或如何到达。

您必须知道要接收多少字节，或者在发送所有内容时断开连接。
