load csv www

What type is csvFile? Can you post the declaration?

This is the complete script:

 using UnityEngine;
 using System.Collections;
 using System.Linq; 
 using System.Text;
 using System.IO;
 
 public class CSVReaderWeb : $$anonymous$$onoBehaviour 
 {
     public TextAsset csvFile; 
     public string csvText; 
     public string mat;
     public string model;
     public string price;
     int i ;
     int j;
     public int x;
     public int y;
     private bool Found$$anonymous$$at;
     private bool Found$$anonymous$$odel;
     string[,] grid;
     public string url;
     
     public void Awake()
     {}

     IEnumerator LoadCSV(){
         WWW www = new WWW (url);
         yield return www;
         csvText = www.text;
     }
 
      public void Start(){
 
         StartCoroutine (LoadCSV());
         grid = SplitCsvGrid(csvFile.text);
     }
     
     public void Update (){
         x = 0;
         y = 0;
         for (int i = 0; i < grid.GetUpperBound(0); i++) {
             if (grid [i, 0] == mat) {
                 x = i;
             }
         }
         
         for (int j = 0; j < grid.GetUpperBound(1); j++) {
             if (grid [0, j] == model) {
                 y = j;
             }
         }
 
         if (x == 0) {
             price = "$$anonymous$$at_null";
         } 
         else if (y == 0) {
             price = "$$anonymous$$odel_null";
         }
         else {
             price = grid [x, y];
         }
         
         
     }
     
 
 
     
     // splits a CSV file into a 2D string array
     static public string[,] SplitCsvGrid(string csvText)
     {
         string[] lines = csvText.Split("\n"[0]); 
         
         // finds the max width of row
         int width = 0; 
         for (int i = 0; i < lines.Length; i++)
         {
             string[] row = SplitCsvLine( lines[i] ); 
             width = $$anonymous$$athf.$$anonymous$$ax(width, row.Length); 
         }

             {
                 outputGrid[x,y] = row[x]; 
                 
                 // This line was to replace "" with " in my output. 
                 // Include or edit it as you wish.
                 outputGrid[x,y] = outputGrid[x,y].Replace("\"\"", "\"");
             }
         }
         
         return outputGrid; 
     }

                                                                                                             System.Text.RegularExpressions.RegexOptions.ExplicitCapture)
                 select m.Groups[1].Value).ToArray();
     }
 }

I would only read the CSV file from URL. Thanks.

public TextAsset csvFile;
