这一章我将继续上一章内容进一步完善我们的串口通信，并添加对话框的美观设计。
首先我们说一下双向通讯，上一章我们实现了单向接收功能，这里将说一下发射功能：
数据发送，总共有三种形式，发送字符串类，发送byte类，发送char类。要实现这三种，都必须调用串口写操作方法 SerialPort.Write（） ，该方法对于不同类型的发送，通过方法重载的方式定义了相应的方法：
- public void Write (string str); 发送字符串
- public void Write (byte[] buffer, int offset, int count); 发送byte类型
- public void Write (char[] buffer, int offset, int count); 发送char类型
本例程发送的是加密后的序列号码，所以只需调用 myPort.Write(output,0,output.Length); 方法即可。此外我们添加一个清空按键:
private void Btn2_Click(object sender, RoutedEventArgs e)
{
m_textBox1.Text = "";
m_textBox2.Text = "";
}
<Button Content="Clear" HorizontalAlignment="Right" VerticalAlignment="Bottom" Width="51" Margin="0,0,22,80" Click="Btn2_Click" Height="58"/>
同时为了美观对话框，我们加入之前定义好的按键动态效果模板来实现按键的动态效果，和加入对label字体格式，textbox背景颜色，以及对话框背景修改：

因为我们之前定义好的模板，我们直接调用即可，这些方法我们也可以运用到其他的设计中。这样做的目的是大大的缩短了我们设计的时间。
