C# 串口通信的图形用户界面

我是C和Visual Studio的新手。我在Visual Studio 2013中构建了一个GUI，用于从菜单中选择COM端口。我想知道的是如何将其与串行端口通信连接起来

我应该使用另一个类进行串行通信吗？或者我可以在同一个班上做吗？如何编程

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.IO.Ports;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.IO;
namespace exo_new
{
public partial class rehab : Form
{
    public rehab()
    {
        InitializeComponent();
    }

    private void textBox1_TextChanged(object sender, EventArgs e)
    {

    }

    private void conndToolStripMenuItem_Click(object sender, EventArgs e)
    {

    }

    private void cOM1ToolStripMenuItem_Click(object sender, EventArgs e)
    {
        cOM1ToolStripMenuItem.Checked = true;
        cOM2ToolStripMenuItem.Checked = false;
        cOM3ToolStripMenuItem.Checked = false;
        cOM4ToolStripMenuItem.Checked = false;
        cOM5ToolStripMenuItem.Checked = false;
        cOM6ToolStripMenuItem.Checked = false;
        cOM7ToolStripMenuItem.Checked = false;
        cOM8ToolStripMenuItem.Checked = false;
        cOM9ToolStripMenuItem.Checked = false;
        cOM10ToolStripMenuItem.Checked = false;
    }

    private void cOM2ToolStripMenuItem_Click(object sender, EventArgs e)
    {
        cOM2ToolStripMenuItem.Checked = true;
        cOM1ToolStripMenuItem.Checked = false;
        cOM3ToolStripMenuItem.Checked = false;
        cOM4ToolStripMenuItem.Checked = false;
        cOM5ToolStripMenuItem.Checked = false;
        cOM6ToolStripMenuItem.Checked = false;
        cOM7ToolStripMenuItem.Checked = false;
        cOM8ToolStripMenuItem.Checked = false;
        cOM9ToolStripMenuItem.Checked = false;
        cOM10ToolStripMenuItem.Checked = false;
    }

您可以使用该类从.NET应用程序编程串行端口。该链接指向该类的MSDN文档，其中包括一个示例程序。如果您需要更多的帮助，那么您需要提供一些代码，更多地解释您想做什么，以及什么时候做。例如，用户单击按钮X，您希望发送消息Y

更新：感谢您迄今为止分享您的代码。以下是我将如何根据您开始的内容实施一个简单的解决方案：

public partial class rehab : Form
{
    private string portName = "COM1";
    private const int baudRate = 9600;

    public Form1()
    {
        InitializeComponent();

        //TODO: Simplify your UI by dynamically creating the COM port names.
        //      Get the list of available ports on the computer via the following:
        //var portNames = SerialPort.GetPortNames();

        // Call this to initially mark 'COM1' as checked.
        UpdatePortCheckmarks();
    }

    private void conndToolStripMenuItem_Click(object sender, EventArgs e)
    {
        var textToSend = this.textBox1.Text;

        // Use a try-catch block to log any exceptions that occur.
        try
        {
            // Use a using block to close and dispose of the serial port
            // resource automatically. Also, note that the SerialPort
            // constructor takes the port name and baud rate here.
            // There are also overloads that let you pass the number of
            // data bits, parity, and stop bits, if needed.
            using (var serialPort = new SerialPort(portName, baudRate))
            {
                // Open the port before writing to it.
                serialPort.Open();

                // Send the content of the textbox (with a newline afterwards).
                serialPort.WriteLine(textToSend);
            }
        }
        catch (Exception ex)
        {
            // You could also use MessageBox.Show. Console.WriteLine will
            // display errors in your debugger's output window.
            Console.WriteLine("ERROR: " + ex.ToString());
        }
    }

    private void cOM1ToolStripMenuItem_Click(object sender, EventArgs e)
    {
        portName = "COM1";
        UpdatePortCheckmarks();
    }

    private void cOM2ToolStripMenuItem_Click(object sender, EventArgs e)
    {
        portName = "COM2";
        UpdatePortCheckmarks();
    }

    // .. and so on for each additional port menu item (COM3 through COM10)

    // This method lets you share the code for updating the checkmarks on
    // the menu items, so your form code will be cleaner.
    private void UpdatePortCheckmarks()
    {
        cOM1ToolStripMenuItem.Checked = portName == "COM1";
        cOM2ToolStripMenuItem.Checked = portName == "COM2";
        cOM3ToolStripMenuItem.Checked = portName == "COM3";
        cOM4ToolStripMenuItem.Checked = portName == "COM4";
        cOM5ToolStripMenuItem.Checked = portName == "COM5";
        cOM6ToolStripMenuItem.Checked = portName == "COM6";
        cOM7ToolStripMenuItem.Checked = portName == "COM7";
        cOM8ToolStripMenuItem.Checked = portName == "COM8";
        cOM9ToolStripMenuItem.Checked = portName == "COM9";
        cOM10ToolStripMenuItem.Checked = portName == "COM10";
    }
}

我已经加入了一个“TODO”注释，作为如何进一步改进代码的建议，但这是可选的，如果您对此有任何疑问，这应该是一个新问题。

非常感谢您。用户从用户界面选择任何端口，该端口用于连接计算机。然后用户单击连接。信息会被发送的。非常感谢。我有一些问题要做。我将把它作为一个新问题发布。拉尔斯，我在这方面又遇到了一个问题。我应该把它作为新问题发布吗？当我选择一个COM端口，然后单击“连接”时，它会显示“找不到COM1”。即使我单击了COM2，它也会显示“COM1”。如果我提供的代码回答了您最初的问题，那么最好询问一个新的端口，并包含您现在拥有的更新代码。顺便说一句，我看到了你的另一个问题-不要以为人们会阅读你的其他问题来了解上下文！几乎没有人会花时间去做那件事
