我正在尝试向机器发送用户名和密码身份验证响应,但我收到了以下错误
不允许发送或接收数据的请求,因为套接字未连接(使用sendto调用在数据报套接字上发送时)没有提供地址
static void Main(string[] args)
{
Socket sck = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
sck.Bind(new IPEndPoint(IPAddress.Parse("192.168.5.40"), 10022));
sck.Listen(1);
Socket accepted = sck.Accept();
byte[] buffer = Encoding.Default.GetBytes("Test post");
accepted.Send(buffer, 0, buffer.Length, 0);
buffer = new byte[255];
int rec = accepted.Receive(buffer, 0, buffer.Length, 0);
Array.Resize(ref buffer, rec);
Console.WriteLine("Recieved: {0}", Encoding.Default.GetString(buffer,24,buffer.Length-24));
Console.WriteLine("Recieved: {0}", BitConverter.ToString(buffer, 0, 24));
string hexValues = "00-00-00-01-f8-a0-3d-48-0b-6d-00-00-3d-0a-bf-09-00-00-00-57-00-10-00-00-00";
byte[] hex = StringToByteArray(hexValues);
sck.Send(hex, 0, hex.Length, 0);
sck.Close();
accepted.Close();
Console.Read();
}
答案 0 :(得分:4)
您尝试在侦听传入连接的套接字上发送数据:
sck.Send(hex, 0, hex.Length, 0);
您应该通过accepted
发送它:
accepted.Send(hex, 0, hex.Length, 0);
