C#通过注册表列出所有串口的实例

 

using Microsoft.Win32;RegistryKey hklm = Registry.LocalMachine;RegistryKey software = hklm.OpenSubKey("HARDWARE");RegistryKey no1 = software.OpenSubKey("DEVICEMAP");RegistryKey no2 = no1.OpenSubKey("SERIALCOMM");string[] linesplit = no2.GetValueNames();if(linesplit.Length <= 0){    MessageBox.Show("there is no COM");}else{    for (int i = 0; i < linesplit.Length; i++ )    {        cbxPort.Items.Add(no2.GetValue(linesplit[i]));    }}

假设已经有一个comboBox的控件，此时，cbxPort里就已经列出所有串口的名称。
