Problème pour lire un csv dans un website

Bonsoir à tous,

J'essai désepèrement de charger un csv dans un GridView (site web) en C#.
J'ai réussi sans problème, dans une application windows form, à le faire.

Voici le code windows form (qui fonctionne bien donc):

using System.Data.OleDb;
 
namespace AfficheCsv
{
    public partial class Form1 : Form
    {
        private DataSet GetCVSFile(string pathfilename)
        {
            string path = Path.GetDirectoryName(pathfilename);
            string filename = Path.GetFileName(pathfilename);
            OleDbConnection ExcelConnection = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path + ";Extended Properties=\"text;HDR=Yes;FMT=Delimited\"");
            OleDbCommand ExcelCommand = new OleDbCommand(@"SELECT * FROM " + filename, ExcelConnection);
 
            OleDbDataAdapter ExcelAdapter = new OleDbDataAdapter(ExcelCommand);
 
            ExcelConnection.Open();
 
            DataSet ExcelDataSet = new DataSet();
            ExcelAdapter.Fill(ExcelDataSet, filename);
 
            ExcelConnection.Close();
            return ExcelDataSet;
        } 
 
        public Form1()
        {
            InitializeComponent();
            string pathfilename = @"D:\Mes Documents\Visual Studio 2005\WebSites\csv\restaurants.csv";
            DataSet ds = GetCVSFile(pathfilename);
 
 
            dataGridView1.AutoGenerateColumns = true;
            dataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells;
            dataGridView1.DataSource = ds.Tables[0];
        }
 
    }
}

et celui dans le site web :

    private DataSet GetCVSFile(string pathfilename)
    {
        string path = Path.GetDirectoryName(pathfilename);
        string filename = Path.GetFileName(pathfilename);
        OleDbConnection ExcelConnection = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path + ";Extended Properties=\"text;HDR=Yes;FMT=Delimited\"");
        OleDbCommand ExcelCommand = new OleDbCommand(@"SELECT * FROM " + filename, ExcelConnection);
 
        OleDbDataAdapter ExcelAdapter = new OleDbDataAdapter(ExcelCommand);
 
        ExcelConnection.Open();
 
        DataSet ExcelDataSet = new DataSet();
        ExcelAdapter.Fill(ExcelDataSet, filename);
 
        ExcelConnection.Close();
        return ExcelDataSet;
    } 
 
    protected void Page_Load(object sender, EventArgs e)
    {
        string pathfilename = Request.ServerVariables["APPL_PHYSICAL_PATH"] + @"\csv\restaurants.csv";
        DataSet ds = GetCVSFile(pathfilename);
 
        GridView1.AutoGenerateColumns = true;
        GridView1.DataSource = ds.Tables[0];
    }
}

dans ce cas tout s'exécute bien mais le GridView reste désepérement vide :(
