C# 關閉UDP時如何處理？
我在點擊一個按鈕時，會彈出一個窗體Form2,
private void Form2_Load(object sender, EventArgs e)
{
GlobalUDP.UDPClient = new UdpClient();
  GlobalUDP.EP = new IPEndPoint(IPAddress.Parse("255.255.255.255"), 26868);

  IPEndPoint BindEP = new IPEndPoint(IPAddress.Any, 26868);
  byte[] DiscoverMsg = Encoding.ASCII.GetBytes("Discovery:Who is out there?");

  GlobalUDP.UDPClient.Client.Bind(BindEP);
  GlobalUDP.UDPClient.MulticastLoopback = false;
  GlobalUDP.UDPClient.EnableBroadcast = true;

  //Configure ourself to receive discovery responses
  GlobalUDP.UDPClient.BeginReceive(ReceiveCallback, GlobalUDP);

  // Transmit the discovery request message
  GlobalUDP.UDPClient.Send(DiscoverMsg, DiscoverMsg.Length, new System.Net.IPEndPoint(System.Net.IPAddress.Parse("255.255.255.255"), 26868));
  }

當關閉Form2窗體，並再次點開Form2窗體時，會出現如下錯誤：
Only one usage of each socket address (protocol/network address/port) is normally permitted

請教：應該在關閉窗體時如何處理？

在你关闭窗体时要把资源释放完
