Reading a delimited text file in C#

You can of course write your own string parsing code or you can take the easy way and add a reference to Microsoft.VisualBasic within your Visual Studio project and make use of the TextFieldParser

This little snippet loads the content of a delimited text file into a ListView

using Microsoft.VisualBasic.FileIO;
        
private void loadCSVFile(string filePath, string delimiter)
{
    TextFieldParser tfParser = new TextFieldParser(filePath);
    tfParser.TextFieldType = FieldType.Delimited;
    tfParser.SetDelimiters(delimiter);
    string[] curRow;
    ListViewItem lvi;
    while (!tfParser.EndOfData)
    {
        curRow = tfParser.ReadFields();
        lvi = listView1.Items.Add(curRow[0]);
        for (var ci = 1; ci < curRow.Length; ci++)
        {
            lvi.SubItems.Add(curRow[ci]);
        }
    }
    tfParser.Close();
    tfParser.Dispose();
}

Sometimes VB is your friend.

Usual caveats about production code (try/catch etc.)
