c# – 在Windows Phone 8中使用NFC共享文本

这是代码=>

接收者代码：

ProximityDevice device;
long subscribedMessageId;
private void receive_Click(object sender,RoutedEventArgs e)
    {
        device = ProximityDevice.GetDefault();
        if (device != null)
        {
            subscribedMessageId = device.SubscribeForMessage("Windows.SampleMessage",messageReceivedHandler);
        }
    }

    private void messageReceivedHandler(ProximityDevice sender,ProximityMessage message)
    {
        rtextbox.Text = message.DataAsString;
        device.StopSubscribingForMessage(subscribedMessageId);
    }

发件人代码：

ProximityDevice device;
long publishedMessageId;
private void send_Click(object sender,RoutedEventArgs e)
    {
        device = ProximityDevice.GetDefault();
        device.StopPublishingMessage(publishedMessageId);
        if (device != null)
        {
            publishedMessageId = device.PublishMessage("Windows.SampleMessage",textbox1.Text);
            textbox1.Text = "";
        }
    }

这两个代码都出现在不同的页面上.当用户分别单击发送或接收按钮时执行代码.

我是NFC新手,所以任何帮助将不胜感激.
