Script to load csv after build

Question

This code works to load up my csv file to load up the world components, but only in the editor when I hit "play" works fine. What it doesn't do, is if I make a build, it doesn't load from the csv file. I've seen things about Unity's Streaming Asset path yet I'm not sure how to apply that to my script I have here. Is that even what I need? How I make my csv file loadable after a build?

 basePath = Application.dataPath;
 basePath += "/Scenes/BoardCSV/Board.csv";
 width = height = 0;
 string[] rows = System.IO.File.ReadAllLines(basePath);
 foreach(string row in rows) {
     ++width;
     string[] columns = row.Split(',');
     foreach (string column in columns) {
         if (width == 1)
             ++height;
      }
 }

I fixed it. I used this Unity doc as my resource.

1. Created Resource Paths

It states that Mac and Windows builds have different locations for their resource folders. I used the branches mentioned in that doc by creating each folder individually to re-make each path for both Mac and Windows: alt text

2. Updated Code

Then I changed the code a bit to this:

  basePath = Path.Combine(Application.streamingAssetsPath, "Board.csv");
  width = height = 0;
  string[] rows = System.IO.File.ReadAllLines(basePath);
  foreach(string row in rows) {
      ++width;
      string[] columns = row.Split(',');
      foreach (string column in columns) {
          if (width == 1)
              ++height;
       }
  }

3. Added IO Header

Lastly, I had to add "using Unity.IO" as a header file.
