Moving a a json string into a VB.NET dropdownbox - json

Question

I receive the following json string from an API call, and I want to populate a VB.NET Dropdownbox with the 'Essd' + 'Frequency' in the Textfield (e.g. 'Common - 5.5 GHz') and 'Essd' in the Valuefield.
I have found lots of example here of simple one dimensional and jaggered, multi-dimensional, but nothing that manages a simple 2D Array.
I almost done my head trying to resolve this.
json String Below:
