c#winform编写上位机中实现动态坐标

Question

在串口接收到一组一组的横纵坐标值，想把每一组横纵坐标分开使用，在两个textbox控件中分别显示横纵坐标。但是发现并没有实时更新都是只是串口接收到的第一组数据
程序如下：

private void sp_DataReceived(object sender, SerialDataReceivedEventArgs e)
{

        byte[] ReceivedData = new byte[sp.BytesToRead];//创建接收字节数组

                    sp.Read(ReceivedData, 0, ReceivedData.Length);//读取所接收到的数据
                    receivedDatas.AddRange(ReceivedData);


                     textBox3.Text = (Convert.ToInt32(textBox3.Text) + ReceivedData.Length).ToString();
        if (checkBox2.Checked)

        {
            textBox1.Text = Class1.ByteTo16Str(receivedDatas.ToArray());

        }
        else
        {
            textBox1.Text = Encoding.Default.GetString(receivedDatas.ToArray());
            //让文本框获取焦点
            string a = Encoding.Default.GetString(receivedDatas.ToArray());
            string[] sArray = a.Split(',');
           // textBox15.Text = a;
            textBox15.Text = textBox15.Text +"\n"+sArray[0]; 
            textBox16.Text = textBox16.Text + "\n" + sArray[1];
          ![图片说明](https://img-ask.csdn.net/upload/201705/19/1495177633_459101.png)
            this.textBox15.Focus();
            //设置光标的位置到文本尾
            this.textBox15.Select(this.textBox1.TextLength, 0);
            //滚动到控件光标处
            this.textBox15.ScrollToCaret();
            this.textBox16.Focus();
            //设置光标的位置到文本尾
            this.textBox16.Select(this.textBox1.TextLength, 0);
            //滚动到控件光标处
            this.textBox16.ScrollToCaret();
            this.textBox1.Focus();
            //设置光标的位置到文本尾
            this.textBox1.Select(this.textBox1.TextLength, 0);
            //滚动到控件光标处
            this.textBox1.ScrollToCaret();
        }

        是需要timer控件还是怎么样可以实现呢？

Answer 1

textBox1.Text = Encoding.Default.GetString(receivedDatas.ToArray());
//让文本框获取焦点
string a = Encoding.Default.GetString(receivedDatas.ToArray());
string[] sArray = a.Split(',');
int len = sArray.Length
for(int i = 0 ;i<len; i +2){

textBox15.Text = textBox15.Text +"\n"+sArray[i];
textBox16.Text = textBox16.Text + "\n" + sArray[i+1];
后面内容不变
}
