port-scanning

Does C# provide an effective means of scanning the available COM ports? I would like to have a dropdown list in my application wherein the user can select one of the detected COM ports. Creating and populating the dropdown list is not a problem. I just need to know how to scan for the available COM ports using C#. I am using Microsoft Visual C# 2008 Express Edition. Thanks.

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
