C#获取串口列表(可用于实现实时监控串口)

常用的两种方法
方法一：
view plaincopy to clipboardprint?
using Microsoft.Win32;

RegistryKey keyCom = Registry.LocalMachine.OpenSubKey("Hardware\\DeviceMap\\SerialComm");
if (keyCom != null)
{
string[] sSubKeys = keyCom.GetValueNames();
foreach (string sName in sSubKeys)
{
string sValue = (string)keyCom.GetValue(sName);
this.textBox1.Text = this.textBox1.Text + sValue + "\r\n";
}
}
using Microsoft.Win32;
RegistryKey keyCom = Registry.LocalMachine.OpenSubKey("Hardware\\DeviceMap\\SerialComm");
if (keyCom != null)
{
string[] sSubKeys = keyCom.GetValueNames();
foreach (string sName in sSubKeys)
{
string sValue = (string)keyCom.GetValue(sName);
this.textBox1.Text = this.textBox1.Text + sValue + "\r\n";
}
}
方法二：
view plaincopy to clipboardprint?
using System.IO.Ports;

foreach (string vPortName in SerialPort.GetPortNames())
{
this.textBox2.Text = this.textBox2.Text + vPortName + "\r\n";
}
