Very simple C# CSV reader

You can try the some thing like the below LINQ snippet.

string[] allLines = File.ReadAllLines(@"E:\Temp\data.csv");

    var query = from line in allLines
                let data = line.Split(',')
                select new
                {
                    Device = data[0],
                    SignalStrength = data[1],
                    Location = data[2], 
                    Time = data[3],
                    Age = Convert.ToInt16(data[4])
                };

UPDATE: Over a period of time, things evolved. As of now, I would prefer to use this library http://www.aspnetperformance.com/post/LINQ-to-CSV-library.aspx

If there is only ever one line then do something like this:

using System;
using System.IO;

class Program
{
    static void Main()
    {
        String[] values = File.ReadAllText(@"d:\test.csv").Split(',');
    }
}

Here's a simple function I made. It accepts a string CSV line and returns an array of fields:

It works well with Excel generated CSV files, and many other variations.

    public static string[] ParseCsvRow(string r)
    {

        string[] c;
        string t;
        List<string> resp = new List<string>();
        bool cont = false;
        string cs = "";

        c = r.Split(new char[] { ',' }, StringSplitOptions.None);

        foreach (string y in c)
        {
            string x = y;


            if (cont)
            {
                // End of field
                if (x.EndsWith("\""))
                {
                    cs += "," + x.Substring(0, x.Length - 1);
                    resp.Add(cs);
                    cs = "";
                    cont = false;
                    continue;

                }
                else
                {
                    // Field still not ended
                    cs += "," + x;
                    continue;
                }
            }

            // Fully encapsulated with no comma within
            if (x.StartsWith("\"") && x.EndsWith("\""))
            {
                if ((x.EndsWith("\"\"") && !x.EndsWith("\"\"\"")) && x != "\"\"")
                {
                    cont = true;
                    cs = x;
                    continue;
                }

                resp.Add(x.Substring(1, x.Length - 2));
                continue;
            }

            // Start of encapsulation but comma has split it into at least next field
            if (x.StartsWith("\"") && !x.EndsWith("\""))
            {
                cont = true;
                cs += x.Substring(1);
                continue;
            }

            // Non encapsulated complete field
            resp.Add(x);

        }

        return resp.ToArray();

    }
