I'm not in front of a computer with c# right now so I'm not able to fully try this.
What you're going to need to do @Jakob is the following:
- Write a parser that will download the file and store it in memory.
- For each section that you want to "parse" into a c# array (for example
zonearray), you need to setup bounds to begin searching and end searching the file. Example: We know that zonearray starts building the array the two lines after zonearray[i] = new Array(1); and ends on zonearray.sort().
- So with these bounds we can then zip through each line between and parse a C# array. This is simple enough I think that you can figure out. You'll need to keep track of sub-index as well remember.
- Repeat this 2-3 for each array you want to parse (
zonearray, roomarray..etc).
If you can't quite figure out how to code the bounds or how to parse the line and dump them into arrays, I might be able to write something tomorrow (even though it's a holiday here in Canada).
EDIT: It should be noted that you can't use some JSON parser for this; you have to write your own. It's not really that difficult to do, you just need to break it into small steps (first figure out how to zip through each line and find the right "bounds").
HTH
EDIT: I just spent ~20 minutes writing this up for you. It should parse the file and load each array into a List<string[]>. I've heavily commented it so you can see what's going on. If you have any questions, don't hesitate to ask. Cheers!
