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 != )
{
//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 != )
comboBox_SPort.Items.Add(port);
}
}
//设置初始显示的值
comboBox_SPort.SelectedIndex = ;
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 = ;
serialPort.DataBits = ;
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[]; // C#创建数组的方法
buf[] = channel;
buf[] = level;
buf[] = (byte)''; if (serialPort != null && serialPort.IsOpen)
{
serialPort.Write(buf,,); // 向串口写入数据
}
}
}
} 文件"Form1.Designer.cs"里包含的函数"InitializeComponent();"
namespace TB528E4PSE_APP
{

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：
