Reading, splitting, and displaying a multiline CSV file in C#

Question

All,

I\'m trying to write a testbed program that will eventually allow me to take a CSV .txt file and put its contents into a SQLite database file. There are hundreds o

This is how I would do it:

First, define a class to hold the output of your file:

public class MyData
{
    public MyData() { }

    public MyData(string[] values)
    {
        Time = new DateTime(long.Parse(values[0]));
        HlState = int.Parse(values[1]);
        HLX = double.Parse(values[2]);
        HLY = double.Parse(values[3]);
        HLZ = double.Parse(values[4]);
    }

    public DateTime Time { get; set; }
    public int HLState { get; set; }
    public double HLX { get; set; }
    public double HLY { get; set; }
    public double HLZ { get; set; }
}

Then modify you button event to populate a list of those objects

    private void btnLoad_Click(object sender, RoutedEventArgs e)
    {
        Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();
        dlg.FileName = "Document";
        dlg.DefaultExt = ".txt";
        dlg.Filter = "Text Documents (.txt)|*.txt";

        if (dlg.ShowDialog() == true)
        {
            fileName = dlg.FileName;
            OutputConsole.Text = " ";
            OutputConsole.Text = fileName;

            var output = new List();

            try
            {
                // First line skipped as we do not need headers.
                foreach (var line in File.ReadAllLines(filename).Skip(1))
                {
                    output.Add(new MyData(line.Split(",")));
                }

                OutputConsole.Text = string.Format("{0} lines read.", output.Lenght);
            }
            catch (System.IO.IOException ex)
            {
                //let user know there was an error reading file
            }

            // Do something with output

        }
    }

Now you have a collection output of objects each with a strong typed access to your values, which should easily populate into a DB
