做UDP/TCP怎么能不用死循环

Question

如题！请高手给代码示例！

Answer 1

使用异步方式..
这个可能对你有帮助

Answer 2

     public void BeginAcceptData()
        {
            udpclient.Client.BeginReceiveFrom(so.buffer, 0, so.buffer.Length, SocketFlags.None, ref ep, new AsyncCallback(ReceiveCallback), null);
        }
        public void ReceiveCallback(IAsyncResult iar)
        {
            try
            {
                IPEndPoint ipe = (IPEndPoint)iep;
                int receiveBytes = udpclient.Client.EndReceiveFrom(iar, ref ep);
                if (receiveBytes > 0)
                {
                    byte[] receiveByte = new byte[receiveBytes];
                    Array.Copy(so.buffer, 0, receiveByte, 0, receiveBytes);
                    UDPdata udata = new UDPdata();
                    udata.date = receiveByte;
                    udata.ep = ipe;
                    ReceiveData(this, new UDPNetEventArgs(udata));
                }
                udpclient.Client.BeginReceiveFrom(so.buffer, 0, so.buffer.Length, SocketFlags.None, ref ep, new AsyncCallback(ReceiveCallback), null);
            }
            catch
            {
            }
        }回调

public void BeginAcceptData() 
        { 
            udpclient.Client.BeginReceiveFrom(so.buffer, 0, so.buffer.Length, SocketFlags.None, ref ep, new AsyncCallback(ReceiveCallback), null); 
        } 
        public void ReceiveCallback(IAsyncResult iar) 
        { 
            try 
            { 
                IPEndPoint ipe = (IPEndPoint)iep; 
                int receiveBytes = udpclient.Client.EndReceiveFrom(iar, ref ep); 
                if (receiveBytes > 0) 
                { 
                    byte[] receiveByte = new byte[receiveBytes]; 
                    Array.Copy(so.buffer, 0, receiveByte, 0, receiveBytes); 
                    UDPdata udata = new UDPdata(); 
                    udata.date = receiveByte; 
                    udata.ep = ipe; 
                    ReceiveData(this, new UDPNetEventArgs(udata)); 
                } 
                udpclient.Client.BeginReceiveFrom(so.buffer, 0, so.buffer.Length, SocketFlags.None, ref ep, new AsyncCallback(ReceiveCallback), null); 
            } 
            catch 
            { 
            } 
        } 

Answer 4

UDP本来就是发出去就不负责的，根本不存在等的问题。

比较简单的例子

Answer 6

看错LZ的意思不用循环，采用异步编程，实质上是采用了递归算法

这个是TCP异步编程的例子
