我正在将Arduino信息读入C#但是当我想通过按btnStop来停止阅读信息时,我总是得到" IOException未处理"为什么呢?
显示的错误在下面评论。 C#代码如下:
public Form1()
{
InitializeComponent();
}
private void btnStart_Click(object sender, EventArgs e)
{
serialPort1.PortName = txtPortName.Text;
serialPort1.BaudRate = 9600;
serialPort1.Open();
serialPort1.DataReceived += new SerialDataReceivedEventHandler(serialPort1_DataReceived);
serialPort1.DataReceived += serialPort1_DataReceived;
}
void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
try
{
Data = serialPort1.ReadLine(); //----->>>ERROR SHOWN HERE
this.Invoke(new EventHandler(displaydata_event));
}
catch (IOException ex5)
{
MessageBox.Show("ERROR:" + ex5);
}
}
void displaydata_event(object sender, EventArgs e)
{
txtData.AppendText(Data + "\n");
}
private void btnStop_Click(object sender, EventArgs e)
{
try
{
serialPort1.Close();
}
catch (IOException ex2)
{
txtData.AppendText("Close error: " + ex2 + "\n");
}
}
}
