綁定UDP套接字連接到特定的本地端點

Question

我這樣做：

Socket socket = new Socket(SocketType.Dgram, ProtocolType.Udp); 
socket.Bind(new IPEndPoint(new IPAddress(new byte[] {192, 168, 1, 8}), 45678)); 
socket.BeginConnect(new IPEndPoint(new IPAddress(new byte[] { 65, 52, 108, 52 }), 80), null, null); 
socket.Send(new byte[] { 1, 2, 3 }); 

但插座沒有真正綁定到本地IP地址192.168.1.8，只是端口：

UDP 0.0.0.0:45678   *:* 

爲什麼？

Answer 1

我用錯了重載的構造套接字：

Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); 
socket.Bind(new IPEndPoint(new IPAddress(new byte[] {192, 168, 1, 8}), 45678)); 
socket.BeginConnect(new IPEndPoint(new IPAddress(new byte[] { 65, 52, 108, 52 }), 80), null, null); 
socket.Send(new byte[] { 1, 2, 3 }); 

現在它正確綁定：

UDP 192.168.1.8:45678  *:*
