Parse/read csv file using C#

Download "A Fast CSV Reader":At first you have to import the external library. It's called A Fast CSV Reader, made by Sebastien Lorion. Download binaries from codeproject.com. It's shown there as well how to use it. I am going to show my example, maybe its more straight forward.

Add "A Fast CSV Reader" to your project:Your project, there are References. You can see them from Solution Explorer. Just add reference and from Browse tab select you downloaded dll file. Also add it with the using statement.

Using "A Fast CSV Reader":

Source code viewer
List<string> product_codes = new List<string>();
using(CsvReader csv = new CsvReader(new StreamReader(input_file_dir.Text), true))
{
    int fieldCount = csv.FieldCount;
 
    string[] headers = csv.GetFieldHeaders();
    while (csv.ReadNextRecord())
    {
        for (int i = 0; i < fieldCount; i++)
        {
            product_codes.Add(csv[i]);
        }
    }
}
