优化逻辑
串口配置入库
新建数据表，sysconf。字段包含data，type，intime
串口配置type：comconf data：（json格式） { "port": "COM1", "baute": "9600", "devaddr": "3" }
开机启动自动打开串口
/// <summary>
/// 初始化加载
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void MainFrom_Load(object sender, EventArgs e)
{
DataTable dt = DB_SerAPI.GetComConfFromDB();
if (dt != null && dt.Rows.Count > 0)
{
Global.ComConfInfo = JObject.Parse(dt.Rows[0]["data"].ToString());
//打开串口
string comname = Global.ComConfInfo["port"].ToString();
//波特率
int baudrate = int.Parse(Global.ComConfInfo["baute"].ToString());
//打开串口
Global.Runport = ComPort.V_OpenPort8N1(comname, baudrate);
if (Global.Runport == null)
MessageBox.Show("打开串口失败");
}
else
MessageBox.Show("获取串口配置失败，请重新配置");
}
系统配置界面逻辑修改
using Newtonsoft.Json.Linq;
using System;
using System.Drawing;
using System.Windows.Forms;
namespace THSensor
{
public partial class Sysconf : Form
{
/// <summary>
/// 串口口配置类
/// </summary>
public Sysconf()
{
InitializeComponent();
}
/// <summary>
/// 打开串口
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button1_Click(object sender, EventArgs e)
{
try
{
if (Global.Runport.IsOpen)
{
Global.Runport.Close();
MessageBox.Show("串口已关闭");
this.button1.Text = "打 开 串 口";
this.button1.BackColor = Color.LightGreen;
}
else
{
//串口
string comname = this.comboBox1.Text;
//波特率
int baudrate = int.Parse(this.comboBox2.Text);
//入库
JObject confinfo = new JObject();
confinfo.Add("port",comname);
confinfo.Add("baute",baudrate);
confinfo.Add("devaddr",this.textBox1.Text);
DB_SerAPI.SetComConfToDB(confinfo.ToString());
//打开串口
Global.Runport = ComPort.V_OpenPort8N1(comname, baudrate);
if (Global.Runport != null)
{
MessageBox.Show("打开串口成功");
this.button1.Text = "关 闭 串 口";
this.button1.BackColor = Color.DarkGray;
}
else
MessageBox.Show("打开串口失败");
}
}
catch (Exception ex)
{
MessageBox.Show(ex.StackTrace +"\r\n"+ ex.Message);
}
}
/// <summary>
/// 加载函数
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void Sysconf_Load(object sender, EventArgs e)
{
//扫描串口
string[] comlist = ComPort.V_ScanPort();
if (comlist.Length < 1)
{
MessageBox.Show("没有扫描到串口，请检查硬件连接");
return;
}
else
{
foreach (string name in comlist)
{
this.comboBox1.Items.Add(name);
}
}
//波特率初始化
this.comboBox2.Items.Add("4800");
this.comboBox2.Items.Add("9600");
this.comboBox2.Items.Add("115200");
//默认
if (Global.ComConfInfo != null && Global.ComConfInfo.ContainsKey("port"))
{
this.textBox1.Text = Global.ComConfInfo["devaddr"].ToString();
this.comboBox2.Text = Global.ComConfInfo["baute"].ToString();
this.comboBox1.Text = Global.ComConfInfo["port"].ToString();
}
//判断是否打开串口
if (Global.Runport.IsOpen)
{
this.button1.Text = "关 闭 串 口";
this.button1.BackColor = Color.DarkGray;
}
else
{
this.button1.Text = "打 开 串 口";
this.button1.BackColor = Color.LightGreen;
}
}
}
}
以上，软件打开后，会自动的打开配置的串口。需要修改的时候，再进入串口配置修改。

实现窗口平铺显示
修改mianwin界面
增加代码
/// <summary>
/// 垂直平铺
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void 垂直平铺ToolStripMenuItem_Click(object sender, EventArgs e)
{
this.LayoutMdi(MdiLayout.TileVertical);
}
/// <summary>
/// 水平平铺
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void 水平平铺ToolStripMenuItem_Click(object sender, EventArgs e)
{
this.LayoutMdi(MdiLayout.TileHorizontal);
}
