C# server监听client端连接，连接成功后，直接给client发消息





try

            {

                while (true)

                {

                    if (_listener.Pending())

                    {

                        TcpClient client = _listener.AcceptTcpClient();

                        NetworkStream stream = client.GetStream();

                        Connection connection = new Connection(stream);

                        this._connections.Add(connection);

                        this.OnConnected(this, new ConnectionEventArgs(connection, new Exception("连接成功")));

连接成功后，随后给client发送消息在注释间的代码，写成最原始的代码了(本来是写在线程里的，但是根本没执行)，程序是执行完这几句了，但是没有发送出去。初接触socket 请帮帮忙 --------------------编程问答-------------------- 具体需求就是客户端发起连接，server端根据连接发送字符过去， client再回消息给server端。现在server端能接收到消息。但是client连过来必须先发送消息过去 --------------------编程问答-------------------- 注意下面 SerializeBinary 和DeSerializeBinary

#region Binary Serializers
public   System.IO.MemoryStream SerializeBinary(object request)
{
System.Runtime.Serialization.Formatters.Binary.BinaryFormatter serializer = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
System.IO.MemoryStream memStream = new System.IO.MemoryStream();
serializer.Serialize(memStream, request);
return memStream;
}

public   object DeSerializeBinary(System.IO.MemoryStream memStream)
{
　 memStream.Position=0;
　 System.Runtime.Serialization.Formatters.Binary.BinaryFormatter deserializer = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
　 object newobj = deserializer.Deserialize(memStream);
　 memStream.Close();
　 return newobj;
}
#endregion

//这里是将消息发送个对方
public void sendMessageToOneUser(ClassMsg msg, System.Net.IPAddress Ip, int Port)//发送消息到用户的一个联系人
        {
            msg.ID = selfInfo.ID;//标识本人的ID号
            this.sockUDP1.Send(Ip, Port, new ClassSerializers().SerializeBinary(msg).ToArray());
        } --------------------编程问答--------------------



                TcpClient tcp = new TcpClient(chatip, chatport);

                NetworkStream network = tcp.GetStream();

                StreamWriter sw = new StreamWriter(network);

                sw.WriteLine(textBox1.Text);

                sw.Flush();

                sw.Close();

                network.Close();

--------------------编程问答--------------------







tcpListener = new TcpListener(8090);  

tcpListener.Start();         

this.listen = true;

while (listen)

{

    Socket s = tcpListener.AcceptSocket();  

    Byte[] stream = new Byte[100];                                

    int i = s.Receive(stream);                     

    message = System.Text.Encoding.UTF8.GetString(stream);                     

}

--------------------编程问答-------------------- 应该用一个TIMER控件测试一下这个即可
当连接成功后，就传信息、 --------------------编程问答--------------------

C# code

                TcpClient tcp = new TcpClient(chatip, chatport);
                NetworkStream network = tcp.GetStream();
                StreamWriter sw = new StreamWriter(network);
   ……

这个network 不能取我监听里的stream 吗 --------------------编程问答--------------------

能具体点吗 timer测试什么本人初学，望指教 --------------------编程问答--------------------

    Socket s = tcpListener.AcceptSocket();
    Byte[] stream = new Byte……

你这个是侦听接收把 --------------------编程问答--------------------

--------------------编程问答-------------------- 为什么发送不出去呢抓包也没抓到
