How to read columns of a tab delimited text file.

I need to read each column value of a tab delimited file.
The file is retrieved.
The column values are not returned.
What do I need to modify?
Thanks,

Source file:
Tab delimited

Date      OldExchange      OldSymbol      NewExchange      NewSymbol
20120315      OTCBB            REFGD      OTCBB            REFG
20120315      OTCBB            SRWY      OTCBB            SRWYD
20120309      OTCBB            ALDFF      AMEX            AXX
20120307      OTCBB            SRCPD      NASDAQ            SRCP

I need to get the column values of each column.

str1 = value of first column "20120315";
str2 = value of 2nd column "OTCBB";
etc.

This is what I have now:
 while ((line = sr.ReadLine()) != null)
        {
            values = line.Split(new char[] { ',' });
            values[values.Length - 1] = values[values.Length - 1].Trim(new char[] { '"' });

           
values[0];
//Returns values[0] as "20120315\tOTCBB\tREFGD\tOTCBB\tREFG"

values[1];
//error Index was outside the bounds of the array.

How do I return the actual column values?

Your logic is splitting on a comma, but you say its a tab-delimited file. Have you tried changing the delimiter for your split?

e.g.

...

values = line.Split(new char[] { '\t' });

...

here is another solution which looks like better and fast in parsing files(like csv)
http://www.codeproject.com/Articles/9258/A-Fast-CSV-Reader

Just see that you change the csv delimiter with \t.

Here is a simple solution:-
public List<string[]> parseCSV(string path)
{
  List<string[]> parsedData = new List<string[]>();

  try
  {
    using (StreamReader readFile = new StreamReader(path))
    {
      string line;
      string[] row;

      while ((line = readFile.ReadLine()) != null)
      {
        row = line.Split(new char[] { '\t' });
        parsedData.Add(row);
      }
    }
  }
  catch (Exception e)
  {
    throw;
  }

  return parsedData;
}

Here is code for you used '\t' as deliminator in Spilt method

using System;
using System.IO;

namespace ConsoleApplication3
{
    class Program
    {
        static void Main(string[] args)
        {
            //read from textfile1.txt
            using (StreamReader sr = new StreamReader("TextFile1.txt"))
            {
                string line = String.Empty;
                string[] values = null;

                while ((line = sr.ReadLine()) != null)
                {
                    values = line.Split(new char[] { '\t' });
                    values[values.Length - 1] = values[values.Length - 1].Trim(new char[] { '"' });
                    // and you will get all columns in values array as expected

                }
            }
        }
    }
}

If two more people come in and mention using tab instead of comma for the delimiter, does that mean I get a Yahtzee?

The tab delimiter '\t' resolved the issue. Additional detail was also helpful.
