CSV data file to Combo Box

Hello - I'm new to VB.Net programming but I've learned a few tricks in this forum and on the tutorials.
I'm trying to get a CSV-formatted text file to populate a combo box. I have the code below working in a button to send the data to the output window. What do I need to do to get it to fill in the combo box instead? And can this data be filtered? For example, my data has a name and a color. Can I send only the data that includes the color "green" to the combo box?

Thanks in advance!
Brian
