C# 串口助手开发

VS2012的注释与反注释快捷键

注释是(Ctrl+K, Ctrl+C)，实际操作，按住Ctrl键不放，先按K键，再按C键。相当于Ctrl+K加 Ctrl+C的组合键。

反注释是(Ctrl+K, Ctrl+U)。

//调试打印语句

Debug.WriteLine(indata);

获得可用的串口

1.

//获取所有的串口            string[] portlist = SerialPort.GetPortNames();            for (int i = 0; i < portlist.Length; i++)            {                this.comboBox1.Items.Add(portlist[i]);            }  

2.这个方法会出现“未将对象引用设置到对象的实例”，问题出在哪里了呢？

这种方法没行通!

 RegistryKey keycom = Registry.LocalMachine.OpenSubKey("Hardware\\DevinceMap\\SerialComm");            try            {                               string[] subkeys = keycom.GetValueNames();                                string[] str_key = new string[subkeys.Length];                for (int i = 0; i < subkeys.Length; i++)                {                   this.comboBox1.Items.Add(str_key[i]);                }            }            catch (Exception ex)            {                MessageBox.Show(ex.Message);                return;            }

3.错误 1 未能找到类型或命名空间名称“ManagementClass" 解决（VS2012)

这个主要是因为未添加引用，

选中工程，右键，添加引用选项，出现引用管理器对话框，如图

选中缺少的引用。

4.一段获得CPU硬件信息的代码

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows.Forms;using System.Management;namespace test{    public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();        }        public void GetInfo()        {            string cpuInfo = "";//cpu序列号              ManagementClass cimobject = new ManagementClass("Win32_Processor");            ManagementObjectCollection moc = cimobject.GetInstances();            foreach (ManagementObject mo in moc)            {                cpuInfo = mo.Properties["ProcessorId"].Value.ToString();                this.richTextBox1.AppendText("cpu序列号：" + cpuInfo.ToString() + "\r\n ");                            }            //获取硬盘ID              String HDid;            ManagementClass cimobject1 = new ManagementClass("Win32_DiskDrive");            ManagementObjectCollection moc1 = cimobject1.GetInstances();            foreach (ManagementObject mo in moc1)            {                HDid = (string)mo.Properties["Model"].Value;                this.richTextBox1.AppendText("硬盘序列号：" + HDid.ToString() + "\r\n ");            }            //获取网卡硬件地址              ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");            ManagementObjectCollection moc2 = mc.GetInstances();            foreach (ManagementObject mo in moc2)            {                if ((bool)mo["IPEnabled"] == true)                    this.richTextBox1.AppendText("MAC address\t{0}" + mo["MacAddress"].ToString() + "\r\n ");                mo.Dispose();            }        }        public string GetSerialPort()        {            string strPortInfo = " ";            ManagementClass mc = new ManagementClass("Win32_SerialPort");            ManagementObjectCollection moc = mc.GetInstances();            foreach (ManagementObject mo in moc)            {                strPortInfo = strPortInfo + mo["Name"].ToString() + "\r\n ";                           }            return strPortInfo;        }        private void button1_Click(object sender, EventArgs e)        {            string str = GetSerialPort();           // this.richTextBox1.AppendText("dddd");            this.richTextBox1.AppendText(str);            GetInfo();        }    }}

代码已测试，结果如图
