Hi
I hope someone smarter than me can point me in the right direction.
I'm trying to build an SDK Addin that lets users ZoomTo their location of interest, by choosing items from Picklists and a Listbox (States, Meridian, PLSS). Were using REST JSON requests to populate the lists and get the ZoomTo Extents and so on.
But parsing the JSON has been difficult, especially to "reach into" the JSON Results string, and extract specific branches out of JSON Query Results. Say like to get the "features" branch; or the "Polygon" branch; on in my current case the "MultiPolygon"\ "coordinates" branch.
I've been resorting to build my own custom parsing routines in C# -- but figure that there must be a "better" way. Quicker and easier ways would be good too.
Once the "coordinates" are extracted they are converted in to CIM Polygons that get displayed, with a Flashing effect, in a Graphics Layer. That's all working -- for the Extent value boxes anyways.
So my general question is this:
"What is the best way to parse JSON Results (like in the following example) to get out the individual "coordinates" rings -- which will in turn get displayed as CIM Polygons?"
Thank you in advance for any tips, tricks, or insights, that you can provide.
