动态获取本机可用串口，

[ltj1682]

其中Port_Option_tmi 一个[ToolStripMenuItem]，相当于文件-》打开的情况。
我要动态获取本机可用串口，
并添加为Port_Option_tmi的子菜单，只能单选。

C# code

#region 选择端口

private void GetSerialPort() //获取串口列表
{
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);
Port_Option_tmi.DropDownItems.Add(sValue, null, new EventHandler(NoPort_Click));
}
}
}

private void NoPort_Click(object sender, EventArgs e)
{
ToolStripMenuItem mi = (ToolStripMenuItem)sender;
for (int i = 0; i < Port_Option_tmi.DropDownItems.Count; i++)
{
//在这里写除去所有子菜单Checked代码
}
mi.Checked=true;

port = mi.Text;
Port_Main_ss.Text = port;
}
#endregion

获取本机串口有更简便方法：

string[] ports = System.IO.Ports.SerialPort.GetPortNames();

顶一下。

        {
            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);
                    SerialToolStripMenuItem.DropDownItems.Add(sValue, null, new EventHandler(NoPorts_Click));
                }
            }

            for (int i = 0; i < SerialToolStripMenuItem.DropDownItems.Count; i++)
            {
                if (SerialToolStripMenuItem.DropDownItems[i].Text == VariableLib.portName)
                {
                    ((ToolStripMenuItem)(SerialToolStripMenuItem.DropDownItems[i])).Checked = true;
                    SerialToolStripStatusLabel.Text = ((ToolStripMenuItem)(SerialToolStripMenuItem.DropDownItems[i])).Text;
                }
            }
        }
