有没有，如果已经打开/正在使用串行COM端口编程检查一个简单的方法？

通常情况下，我会用：

 尝试
{
    //打开端口
}
赶上（例外前）
{
    //处理异常
}
 

不过，我想以编程方式检查，所以我可以尝试使用其他COM端口或类似。

我需要类似的东西前段时间，来搜索设备。

我获得可用的COM端口的列表，然后简单地遍历他们，如果它没有引发异常我试图与设备进行通信。有点粗糙，但工作。

  VAR port名字= SerialPort.GetPortNames（）;

的foreach（在port名字VAR港）{
    //尝试为每个端口名，并打破第一个工作日
}
 

Is there an easy way of programmatically checking if a serial COM port is already open/being used?

Normally I would use:

try
{
    // open port
}
catch (Exception ex)
{
    // handle the exception
}

However, I would like to programatically check so I can attempt to use another COM port or some such.

I needed something similar some time ago, to search for a device.

I obtained a list of available COM ports and then simply iterated over them, if it didn't throw an exception i tried to communicate with the device. A bit rough but working.

var portNames = SerialPort.GetPortNames();

foreach(var port in portNames) {
    //Try for every portName and break on the first working
}
