如何接收和使用从蓝牙到C＃的整数？ [英] How to receive and using integers from Bluetooth to C#?

问题描述

我正在使用Arduino将数字发送到我的笔记本电脑，而视觉工作室则使用数字并根据执行某项任务所需的数字。问题是我不断收到一条消息，说它无法将int类型转换为System.IO.Ports.SerialPorts。
如何围绕这个进行操作？

使用System; 
使用System.Collections.Generic;使用System.ComponentModel 
; 
使用System.Data; 
使用System.Diagnostics;使用System.Drawing 
; 
使用System.IO.Ports; 
使用System.Linq; 
使用System.Text; 
使用System.Threading.Tasks; 
使用System.Windows.Forms; 
 
 namespace bluetooth_test 
 {
 public partial class Form1：Form 
 {
 int count = 0; 
 public Form1（）
 {
 InitializeComponent（）; 
 serialPort1.PortName =" COM5" ;; 
 serialPort1.BaudRate = 9600; 
 
尝试
 {
 if（！serialPort1.IsOpen）
 serialPort1.Open（）; 
} 
 catch（Exception ex）
 {
 MessageBox.Show（ex.Message）; 
} 
 serialPort1.DataReceived + = new System.IO.Ports.SerialDataReceivedEventHandler（DataReceived）; 
 this.Width = 800; 
 this.Height = 600; 
} 
 
 private void DataReceived（object sender，System.IO.Ports.SerialDataReceivedEventArgs e）
 {
 // throw new NotImplementedException（）; 
 try 
 {
 
 SerialPort spl =（SerialPort）sender; 
 Console.Write（" Data" + count +"" + spl.ReadLine（）+" \ n"）; 
 count ++; 
 if（spl = 1）{} 
} 
 catch（Exception ex）
 {
 
} 
} 
 
 
} 
 
}

嗨Deon，

问题是由于以下代码：

尝试
 {
 SerialPort spl =（SerialPort）sender; 
 Console.Write（" Data" + count +"" + spl.ReadLine（）+" \ n"）; 
 count ++; 
  if（spl = 1）//由于此代码 
 {} 
} 

 

'sql'是 SerialPort 类型的一个实例，1是一个数字，所以你不能在等号的两边比较它们，请检查它。

你想在这做什么？

问候，

I am using Arduino to send numbers to my laptop, and visual studios to take the numbers and depending on what number it is to perform a certain task. The problem is I keep getting a message saying it cannot convert type int to System.IO.Ports.SerialPorts. How can I maneuver around this?

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Drawing;
using System.IO.Ports;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace bluetooth_test
{
    public partial class Form1 : Form
    {
        int count = 0;
        public Form1()
        {
            InitializeComponent();
            serialPort1.PortName = "COM5";
            serialPort1.BaudRate = 9600;
            
            try
            {
                if (!serialPort1.IsOpen)
                    serialPort1.Open();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
            serialPort1.DataReceived += new System.IO.Ports.SerialDataReceivedEventHandler(DataReceived);
            this.Width = 800;
            this.Height = 600;
        }

        private void DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
        {
            // throw new NotImplementedException();
            try
            {
               
                SerialPort spl = (SerialPort)sender;
                Console.Write("Data" + count + " " + spl.ReadLine() + "\n");
                count++;
                if (spl = 1) { }
            }
            catch (Exception ex)
            {

            }
        }

        
    }
    
}

Hi Deon,

The problem is due to the following code:

    try
    {
        SerialPort spl = (SerialPort)sender;
        Console.Write("Data" + count + " " + spl.ReadLine() + "\n");
        count++;
        if (spl = 1)//due to this code
        { }
    }

 

The 'sql' is an instance of the SerialPort type, and 1 is a number, so you can't compare them on both sides of the equal sign, please check it.

What do you want to do here?

Regards,

Frankie
