VS上利用C#实现一个简单的串口程序记录
本篇就C#实现一个简单的串口程序做个简单记录
一、背景
工作上需要利用串口往下位机写入数据，VC太老，正好借此机会来熟悉一直很想接触的VS之C#。
感谢Tony托尼哥的串口通信代码，感谢梦真的C#的技术支持。
二、正文
1、项目架构：（以我现有的知识认知来说）
一共有3个文件：
a、”Program.cs”保存的是主程序入口。
b、”Form1.Designer.cs”图形控件的实现。
c、”Form1.cs”里面实现的既是用户逻辑。
典型代码结构如下:
最先运行文件"Program.cs"内的主程序 namespace TB528E4PSE_APP { static class Program { /// <summary> /// 应用程序的主入口点。 /// </summary> [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new VOUTCTRL());-----------------------| } | } | } | 然后接着运行"Form1.cs" 文件内的"VOUTCTRL()". | namespace TB528E4PSE_APP | { | public partial class VOUTCTRL : Form | { | SerialPort serialPort; | | public VOUTCTRL() <---------------------------------------| { //IntializeComponent()函数在"Form1.Designer.cs"里实现，
//功能是初始化图形界面 //在图形界面操作时，该代码会被VS自动更改 InitializeComponent(); Control.CheckForIllegalCrossThreadCalls = false; //获取串口 String[] serialPortArray = SerialPort.GetPortNames(); if (serialPortArray != null && serialPortArray.Length != 0) { //对串口进行排序 Array.Sort<String>(serialPortArray); foreach (String port in serialPortArray) { //添加到combox的item if (port != null && port.Length != 0) comboBox_SPort.Items.Add(port); } } //设置初始显示的值 comboBox_SPort.SelectedIndex = 0; serialPort = new SerialPort(); } private void button_SPort_Click(object sender, EventArgs e) { // 在图形界面编辑时，双击Button控件，该函数由VS自动生成 // 打开窗口 if (button_SPort.Text == "Open") { if (serialPort.IsOpen) serialPort.Close(); try { setPort(); serialPort.Open(); button_SPort.Text = "Close"; } catch (Exception ex) { MessageBox.Show("Uable to open this serial port!\n"); } } else { button_SPort.Text = "Open"; serialPort.Close(); } } private void trackBar_VOUT1_Scroll(object sender, EventArgs e) { // 在图形界面编辑时，双击trackBar类控件，该函数由VS自动生成 // 拖动trackBar_VOUT1控件实现的逻辑 /* 一些代码逻辑，就不详细贴了。 ... setSerialVOUT(_Channel_1, _LV0); ... */ } private void trackBar_VOUT2_Scroll(object sender, EventArgs e) { // 在图形界面编辑时，双击trackBar类控件，该函数由VS自动生成 // 拖动trackBar_VOUT2控件实现的逻辑 /* 一些代码逻辑，就不详细贴了。 ... setSerialVOUT(_Channel_2, _LV0); ... */ } private void setPort() // 初始化串口 { try { serialPort.PortName = (String)(comboBox_SPort.SelectedItem); serialPort.BaudRate = 115200; serialPort.DataBits = 8; serialPort.StopBits = StopBits.One; serialPort.Parity = Parity.None; } catch (Exception ex) { Console.WriteLine(ex); } } private void setSerialVOUT(byte channel, byte level) { byte[] buf = new byte[3]; // C#创建数组的方法 buf[0] = channel; buf[1] = level; buf[2] = (byte)\'0\'; if (serialPort != null && serialPort.IsOpen) { serialPort.Write(buf,0,3); // 向串口写入数据 } } } } 文件"Form1.Designer.cs"里包含的函数"InitializeComponent();" namespace TB528E4PSE_APP { partial class VOUTCTRL { /// <summary> /// 必需的设计器变量。 /// </summary> private System.ComponentModel.IContainer components = null; /// <summary> /// 清理所有正在使用的资源。 /// </summary> /// <param name="disposing">如果应释放托管资源，为 true；否则为 false。</param> protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); } #region Windows 窗体设计器生成的代码 /// <summary> /// 设计器支持所需的方法 - 不要 /// 使用代码编辑器修改此方法的内容。 /// </summary> private void InitializeComponent() { System.ComponentModel.ComponentResourceManager resources = \

至此，代码跟踪至此。
2、更改窗体在屏幕首次出现的位置
即当APP运行时，窗体会在电脑屏幕的哪个位置弹出。点击窗体->属性，
找到“startposition”，如下图：
注意以上图片包含的信息：Text选项，此处则可以表明窗体显示的信息。
3，更改窗体显示的图标。
即当APP运行时，窗体在Text旁边的图片，点击窗体->属性，
找到“Icon”，如下图：
4、如何发布程序：
点击项目栏“生成”，点击“发布”选项即可发布程序了，如下图：
生成的文件如下图：
点击后缀名为”.application”即可实现安装。
5、发布安装后，程序在桌面显示的图标，以及支持的”.NET frameworkXX.XX”设置。
在项目右击，选择属性，会跳出窗体”项目名.csproj”文件，
里面可进行相应设置，如下图：
