convert string csv to List of objects

Question

I have the following sting

const string csv = "Foo1,Foo2,Foo3,Foo4,Foo5,Foo6,Ping Pong\n" +
                   "2016-02-29,1437.530029,1445.839966,1433.77002,1436.930054,34016300,1436.930054\n" +
                   "2016-02-25,1431.439941,1431.439941,1421.280029,1426.97998,78076500,1426.97998\n" +
                   "2016-02-24,1430.459961,1432.430054,1417.449951,1419.790039,29049900,1419.790039\n";

How I can convert it to List<Model> where

public class Model
{
    public string Foo1 { get; set; }
    public string Foo2 { get; set; }
    public string Foo3 { get; set; }
    public string Foo4 { get; set; }
    public string Foo5 { get; set; }
    public string Foo6 { get; set; }
    public string Ping_Pong { get; set; }
}

Note of the Ping Pong header in my orig csv

I tried to use CsvHelper but with no success as it is taking a stream rather then string and I failed trying to convert a parse

EDIT It does not matter for me if to use CsvHelper or not, in the end I want to convert the csv to List<Model>

How can I do this?

You can create an StringReader using csv variable:

var textReader = new StringReader(csv);

var csvr = new CsvReader(textReader);
var records = csvr.GetRecords<Model>();

If you want your own parser:

var lines = csv.Split(new char[] {'\n'}, StringSplitOptions.RemoveEmptyEntries).Skip(1);
List<Model> models = new List<Model>();

foreach (var item in lines)
{
    var values = item.Split(',');
    var model = new Model
    {
        Foo1 = values[0],
        Foo2 = values[1],
        Foo3 = values[2],
        Foo4 = values[3],
        Foo5 = values[4],
        Foo6 = values[5],
        Ping_Pong = values[6],
    };

    models.Add(model);
}

EDIT:

To resolve the header problem using CsvHelper you need create a map configuration class specifying the mappings between headers and properties:

public class ModelMap : CsvClassMap<Model>
{
    public ModelMap()
    {
        Map(m => m.Foo1);
        Map(m => m.Foo2);
        Map(m => m.Foo3);
        Map(m => m.Foo4);
        Map(m => m.Foo5);
        Map(m => m.Foo6);
        Map(m => m.Ping_Pong).Name("Ping Pong");
    }
}

Using like this:

var textReader = new StringReader(csv);

var csvr = new CsvReader(textReader);
csvr.Configuration.RegisterClassMap<ModelMap>();

var records = csvr.GetRecords<Model>();
