I have tried to use a thread and check the com count but i am unable to know which com is modem.

If there is any specific class for this pls help me fr the code asap???

推荐答案

实现这一目标的方法之一是打开com端口，如

one of the way to achieve this is open the com port like

SerialPort com = new SerialPort("com1");
com.Open();

你可以从i循环到250 com端口如果不成功会抛出异常

并且你可以处理它。

否则它将成功打开端口

your can loop from i to 250 com port if unsuccessful it will throw exception
and you can handle it.
other wise it will successfully open the port
