先看外观，包括选择串口号、波特率、清空接受框、保存等功能

本设计的主体如下

 //串口接收数据//private void Port_DataReceived(object sender, SerialDataReceivedEventArgs e)private void Port_DataReceived(object sender, SerialDataReceivedEventArgs e){while (this.SP != null){ Control.CheckForIllegalCrossThreadCalls = false;string dataRecive = SP.ReadExisting();//输出语句println（）//Console.WriteLine(dataRecive);//使用阻塞io暂停cmd窗口消失//Console.ReadLine();//方法1：// txtReceive.AppendText(DateTime.Now.ToString("yyy-MM-dd hhh:mm ->") + dataRecive);//方法2：//this.txtReceive.Text = this.txtReceive.Text + DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss ->") + dataRecive + "\n" ;this.txtReceive.Text = this.txtReceive.Text + dataRecive ;//不知道为什么加了时间，会断成两截if( dataRecive != null && dataRecive.Length>41){try{Con.Open();string query = "insert into [Table] values('" + DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss") + "', '" + dataRecive.Substring(0, 2) + "','" + dataRecive.Substring(3, 2) + "','" + dataRecive.Substring(6, 8) + "','" + dataRecive.Substring(6, 8) + "','" + dataRecive.Substring(6, 8) + "','" + dataRecive.Substring(33, 8) + "')";SqlCommand cmd = new SqlCommand(query, Con);cmd.ExecuteNonQuery();//MessageBox.Show("保存成功");Con.Close();}catch (Exception Ex){MessageBox.Show(Ex.Message);}}Debug.WriteLine(this.receive);//Debug一下结果//SqlConnection Con = new SqlConnection(@"Data Source=(localdb)\Projects;Initial Catalog=My;Integrated Security=True;Connect Timeout=30;Encrypt=False;TrustServerCertificate=False");同时保存入数据库                }
}

注意需要先链接数据库

 //函数：链接数据库
SqlConnection Con = new SqlConnection(@"Data Source=LAPTOP-3KOP5ILG;Initial Catalog=My;Integrated Security=True;Connect Timeout=30;Encrypt=False;TrustServerCertificate=False;ApplicationIntent=ReadWrite;MultiSubnetFailover=False"); //新建一个全局数据库对象，使用该对象来操作全局的,@""是连接字符串，用于获取/打开SQLserver

其中UWB信号需要的波特率为460800，在前端设计的时候编辑列

初始化串口控件和参数

//初始化串口控件和参数string[] portList = System.IO.Ports.SerialPort.GetPortNames();portList = this.GetDistinct(portList).ToArray();if (portList != null && portList.Length > 0){Array.Sort(portList);this.cboPortList.Items.Clear();this.cboPortList.Items.AddRange(portList);this.cboPortList.SelectedIndex = 0;}this.cboBaudRate.SelectedIndex = 10;this.cboDataBits.SelectedIndex = 2;this.cboParity.SelectedIndex = 0;this.cboStopBits.SelectedIndex = 0;
