ump 中使用ConnectAsync連接服務器出現AccessDenied

            clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

            SocketAsyncEventArgs socketEventArg = new SocketAsyncEventArgs();
            socketEventArg.Completed += new EventHandler<SocketAsyncEventArgs>(OnConnect);
            socketEventArg.RemoteEndPoint = new IPEndPoint(IPAddress.Parse(serverIP), serverPort);
            socketEventArg.UserToken = clientSocket;

            clientSocket.ConnectAsync(socketEventArg);

這段代碼連接失敗，返回AccessDenied。


MSDN的說明是：An attempt was made to access a Socket in a way that is forbidden by its access permissions

權限不夠！

那麼哪裏可以設置權限呢？

1.  Package.appxmanifest => 功能 ，然後勾選即可

2.  Package.appxmanifest => 右鍵 => 查看代碼，然後加入如下代碼

  <Capabilities>
    <Capability Name="internetClientServer" />
    <Capability Name="privateNetworkClientServer" />
  </Capabilities>
