  • 0

I am creating a batch file to remove virtual com ports created before using com0com. at the time of creation, the port names where renamed for example:

change CNCA2 portname=COM20

So when i want to remove i should use the original name like:

remove 2

which corresponds to the original portname CNCA2

So, what i m trying to do here is if the user chooses to remove Port COM20, how can get the
original name which is CNCxx ?

below is the sample of command i used:enter image description here

as u can see, when i write remove COM150 there is no change, so i need to get the corresponding name which is remove 2.

so from the c# application how can i get the corresponding name without manually using a list command?

Thanks.

    You could spawn a command prompt process that runs the list command and capture the output by redirecting stdout to a text file. Then read the results back from the file.

    From the example above, it should be relatively simple to parse the results and use them to create a Dictionary, so you can then easily look up the original name given the new name.
