任何幫助/反饋將不勝感激。我正在開發一個廣播客戶端接收器,以便它接收來自服務器的數據。客戶端異步地發送和接收數據。換句話說,我使用的方法,如socket.BeginReceiveFrom()和socket.BeginSendTo() 然而,我想以某種方式獲得服務器的IP地址,但是當我使用方法RemoteEndPoint()獲取IP服務器地址我得到錯誤。部分代碼如下所示。c#中的異步廣播客戶端#
private void Form1_Load(object sender, EventArgs e) {
byteData = msgToSend.ToByte();
clientSocket.BeginSendTo(byteData, 0, byteData.Length, SocketFlags.None, epServer, new AsyncCallback(OnSend), null);
byteData = new byte[1024];
//Start listening to the data asynchronously
clientSocket.BeginReceiveFrom (byteData,0, byteData.Length,SocketFlags.None,ref epServer,new AsyncCallback(OnReceive),null);
}
private void OnReceive(IAsyncResult ar) {
try {
clientSocket.EndReceive(ar);
byteData = new byte[1024];
// HERE MY CODE TO FIND THE IP ADDRESS OF THE SERVER
IPEndPoint ip = (IPEndPoint)epServer.RemoteEndPoint;
MessageBox.Show(Convert.ToString(ip.Address));
//Start listening to receive more data from the user
clientSocket.BeginReceiveFrom(byteData, 0, byteData.Length, SocketFlags.None, ref epServer,new AsyncCallback(OnReceive), null);
} catch (ObjectDisposedException) {
} catch (Exception ex) {
MessageBox.Show(ex.Message, "SGSclient: " + strName, MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
**您得到了什麼錯誤**? – SLaks
我相信這是你以前的問題的擴展:http://stackoverflow.com/questions/7842443/asynchronous-client-broadcast-receiver/7853129#7853129我在那裏提供的答案應該允許你得到服務器的IP – robowahoo
Thx robowahoo,我剛剛在鏈接中顯示的代碼中看到了我的錯誤。而不是EndReceived()方法,我使用EndReceiveFrom()返回結束點。 –
